A stela and a statuette of the Egyptian pharaohs Senusret III and Amenemhet III have also been found. However, it is unclear when they first arrived at Ugarit. In the Amarna letters , messages from Ugarit c.  1350 BC written by Ammittamru I , Niqmaddu II , and his queen have been discovered. From

354-580: A chemical plant was begun, but construction was interrupted after the collapse of the Soviet Union . In the early 1990s mining in Lisakovsk was in a critical situation due to a sharp fall in demand for iron concentrate in the metallurgical industry in Kazakhstan and Russia . City authorities had to take extraordinary steps to maintain the economy and to develop new industries. By decision of

472-636: A "dark period" in ancient Egyptian history, spanned about 100 years after the end of the Old Kingdom from about 2181 to 2055 BC. Very little monumental evidence survives from this period, especially from the early part of it. The First Intermediate Period was a dynamic time when the rule of Egypt was roughly divided between two areas: Heracleopolis in Lower Egypt and Thebes in Upper Egypt. These two kingdoms eventually came into conflict, and

590-528: A 33% to 40% recovery of magnetite by weight, to produce a concentrate grading in excess of 64% iron by weight. The typical magnetite iron ore concentrate has less than 0.1% phosphorus , 3–7% silica , and less than 3% aluminium . As of 2019, magnetite iron ore is mined in Minnesota and Michigan in the United States , eastern Canada , and northern Sweden . Magnetite-bearing banded iron formation

In modern scholarship, the chronology of the Bronze Age Levant is divided into: The term Neo-Syria is used to designate the early Iron Age . The old Syrian period was dominated by the Eblaite first kingdom , Nagar and the Mariote second kingdom . The Akkadians conquered large areas of

826-696: A benchmark to be followed by the rest of the industry. Singapore Mercantile Exchange (SMX) has launched the world's first global iron ore futures contract, based on the Metal Bulletin Iron Ore Index (MBIOI) which uses daily price data from a broad spectrum of industry participants and independent Chinese steel consultancy and data provider Shanghai Steelhome's widespread contact base of steel producers and iron ore traders across China. The futures contract has seen monthly volumes over 1,500,000 t (1,500,000 long tons; 1,700,000 short tons) after eight months of trading. This move follows

944-536: A blast furnace more efficient. Others are added because they make the iron more fluid, harder, or give it some other desirable quality. The choice of ore, fuel, and flux determines how the slag behaves and the operational characteristics of the iron produced. Ideally, iron ore contains only iron and oxygen. In reality, this is rarely the case. Typically, iron ore contains a host of elements which are often unwanted in modern steel. Late Bronze Age The Bronze Age ( c.  3300  – c.  1200 BC )

1062-402: A permanence not enjoyed by manuscripts. These inscriptions can commonly be subdivided into four parts: a reference to the date and place, the naming of the event commemorated, the list of gifts given to the artisan in exchange for the bronze, and a dedication. The relative points of reference these vessels provide have enabled historians to place most of the vessels within a certain time frame of

1180-579: A power vacuum in Mesopotamia. At its beginning, Mitanni's major rival was Egypt under the Thutmosids . However, with the ascent of the Hittite empire, Mitanni and Egypt allied to protect their mutual interests from the threat of Hittite domination. At the height of its power during the 14th century BC, Mitanni had outposts centred on its capital, Washukanni , which archaeologists have located on

1298-424: A premium price. Due to the high density of hematite relative to associated silicate gangue, hematite beneficiation usually involves a combination of beneficiation techniques. One method relies on passing the finely-crushed ore over a slurry containing magnetite or other agent such as ferrosilicon which increases its density. When the density of the slurry is properly calibrated, the hematite will sink and

1416-453: A relatively low-grade ore, they are also inexpensive to collect, as they do not have to be mined. Because of this, companies such as Magnetation have started reclamation projects where they use iron ore tailings as a source of metallic iron. The two main methods of recycling iron from iron ore tailings are magnetizing roasting and direct reduction. Magnetizing roasting uses temperatures between 700 and 900 °C (1,292 and 1,652 °F) for

1534-481: A small administrative town) appears on a tablet from the reign of Sargon of Akkad in the 23rd century BC. The Amorite dynasty established the city-state of Babylon in the 19th century BC. Over a century later, it briefly took over the other city-states and formed the short-lived First Babylonian Empire during what is also called the Old Babylonian Period . Akkad, Assyria, and Babylonia used

1652-616: A source of iron ore. Prior to the industrial revolution, most iron was obtained from widely-available goethite or bog ore , for example, during the American Revolution and the Napoleonic Wars . Historically, much of the iron ore utilized by industrialized societies has been mined from predominantly hematite deposits with grades of around 70% Fe. These deposits are commonly referred to as "direct shipping ores" or "natural ores". Increasing iron ore demand, coupled with

1770-606: A switch to index-based quarterly pricing by the world's three largest iron ore miners— Vale , Rio Tinto , and BHP —in early 2010, breaking a 40-year tradition of benchmark annual pricing. Iron is the most abundant element on earth but not in the crust. The extent of the accessible iron ore reserves is not known, though Lester Brown of the Worldwatch Institute suggested in 2006 that iron ore could run out within 64 years (that is, by 2070), based on 2% growth in demand per year. Geoscience Australia calculates that

1888-418: A time of under 1 hour to produce an iron concentrate (Fe 3 O 4 ) to be used for iron smelting. For magnetizing roasting, it is important to have a reducing atmosphere to prevent oxidization and the formation of Fe 2 O 3 because it is harder to separate as it is less magnetic. Direct reduction uses hotter temperatures of over 1,000 °C (1,830 °F) and longer times of 2–5 hours. Direct reduction

2006-655: A typically titanium -bearing magnetite, often with vanadium . These ores form a niche market, with specialty smelters used to recover the iron, titanium, and vanadium. These ores are beneficiated essentially similarly to banded iron formation ores, but usually are more easily upgraded via crushing and screening . The typical titanomagnetite concentrate grades 57% Fe, 12% Ti, and 0.5% V 2 O 5 . For every one ton of iron ore concentrate produced, approximately 2.5–3.0 tons of iron ore tailings will be discharged. Statistics show that there are 130 million tons of iron ore tailings discharged every year. If, for example,

According to the U.S. Geological Survey's 2021 Report on iron ore, India is estimated to produce 59,000,000 t (58,000,000 long tons; 65,000,000 short tons) of iron ore in 2020, placing it as

2242-472: Is 175% higher than the corresponding level last year. In comparison with January–May 2009 iron ore (in kind) increased by 0.8%, bauxite by 9.5%, and zinc ore extraction increased 4.5 times. The share of mining citywide was 75.9%. The manufacturing industry in January–May 2010 produced products to 1307 million tenge, which is lower than the corresponding period last year by 4.6%. 80.1% of manufacture by volume

2360-511: Is a high-volume, low-margin business, as the value of iron is significantly lower than base metals. It is highly capital intensive, and requires significant investment in infrastructure such as rail in order to transport the ore from the mine to a freight ship. For these reasons, iron ore production is concentrated in the hands of a few major players. World production averages 2,000,000,000 t (2.0 × 10 long tons; 2.2 × 10 short tons) of raw ore annually. The world's largest producer of iron ore

2478-639: Is an argument to be made that the Bronze Age never properly ended in China, as there is no recognisable transition to an Iron Age. Together with the jade art that precedes it, bronze was seen as a fine material for ritual art when compared with iron or stone. Bronze metallurgy in China originated in what is referred to as the Erlitou period, which some historians argue places it within the Shang. Others believe

A few iron ore deposits, notably in Chile , are formed from volcanic flows containing significant accumulations of magnetite phenocrysts . Chilean magnetite iron ore deposits within the Atacama Desert have also formed alluvial accumulations of magnetite in streams leading from these volcanic formations. Some magnetite skarn and hydrothermal deposits have been worked in

5900-776: The 6th century BC attests to knowledge of iron smelting, yet bronze continues to occupy the seat of significance in the archaeological and historical record for some time after this. W. C. White argues that iron did not supplant bronze "at any period before the end of the Zhou dynasty (256 BC)" and that bronze vessels make up the majority of metal vessels through the Eastern Han period , or to 221 BC. The Chinese bronze artefacts generally are either utilitarian, like spear points or adze heads, or "ritual bronzes" , which are more elaborate versions in precious materials of everyday vessels, as well as tools and weapons. Examples are

8142-533: The country's " economic demonstrated resources " of iron currently amount to 24 gigatonnes , or 24,000,000,000 t (2.4 × 10 long tons; 2.6 × 10 short tons). Another estimate places Australia's reserves of iron ore at 52,000,000,000 t (5.1 × 10 long tons; 5.7 × 10 short tons), or 30% of the world's estimated 170,000,000,000 t (1.7 × 10 long tons; 1.9 × 10 short tons), of which Western Australia accounts for 28,000,000,000 t (2.8 × 10 long tons; 3.1 × 10 short tons). The current production rate from

8260-584: The depletion of high-grade hematite ores in the United States, led after World War II to the development of lower-grade iron ore sources, principally the use of magnetite and taconite . Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite , massive hematite, and pisolitic ironstone deposits. The origin of iron can be ultimately traced to its formation through nuclear fusion in stars, and most of

8378-425: The development of trade networks. A 2013 report suggests that the earliest tin-alloy bronze was a foil dated to the mid-5th millennium BC from a Vinča culture site in Pločnik , Serbia , although this culture is not conventionally considered part of the Bronze Age; however, the dating of the foil has been disputed. West Asia and the Near East were the first regions to enter the Bronze Age, beginning with

8496-733: The discovery of the Europoid Tarim mummies in Xinjiang has caused some archaeologists such as Johan Gunnar Andersson , Jan Romgard, and An Zhimin to suggest a possible route of transmission from the West eastwards. According to An Zhimin, "It can be imagined that initially, bronze and iron technology took its rise in West Asia, first influenced the Xinjiang region, and then reached the Yellow River valley, providing external impetus for

8614-651: The fall of the monarchy. The name "Israel" first appears c.  1209 BC , at the end of the Late Bronze Age and the very beginning of the Iron Age, on the Merneptah Stele raised by the Egyptian pharaoh Merneptah . The Arameans were a Northwest Semitic semi-nomadic pastoral people who originated in what is now modern Syria (Biblical Aram ) during the Late Bronze and early Iron Age. Large groups migrated to Mesopotamia, where they intermingled with

8732-474: The first to develop writing . According to archaeological evidence, cultures in Mesopotamia , which used cuneiform script, and Egypt , which used hieroglyphs , developed the earliest practical writing systems. Bronze Age civilisations gained a technological advantage due to bronze's harder and more durable properties than other metals available at the time. While terrestrial iron is naturally abundant,

8850-534: The form of burial mounds and stone walls. These findings characterize the basic life-support systems and religious ideas of Indo-Iranian tribes that lived in the steppe zone of the Upper Pritobolya in the mid-second millennium BC. The collection of the Lisakovsk city museum, which houses the bulk of the finds, includes more than 200 ceramic vessels, 30 pieces of gold jewelry in the form of rings, more than 40 bronze ornaments (rings, bracelets, ornaments of

8968-442: The gangue is separated during the beneficiation process and is removed as tailings . Taconite tailings are mostly the mineral quartz , which is chemically inert. This material is stored in large, regulated water settling ponds. The key parameters for magnetite ore being economic are the crystallinity of the magnetite, the grade of the iron within the banded iron formation host rock, and the contaminant elements which exist within

9086-800: The groundwater table). Brazil is the second-largest producer of iron ore after Australia, accounting for 16% of the world's iron ore production. After a somewhat sluggish production volume 2010-2020, partly due to the Mariana dam disaster in 2015 and the Brumadinho dam disaster in 2019, which halted the production at the two involved mines, production has increased steadily since 2021, when Brazil produced 431,000,000 t (424,000,000 long tons; 475,000,000 short tons). In 2022 it increased to 435,000,000 t (428,000,000 long tons; 480,000,000 short tons) and in 2023 to 440,000,000 t (430,000,000 long tons; 490,000,000 short tons). The Brazilian production

9204-685: The headwaters of the Khabur River . Eventually, Mitanni succumbed to the Hittites and later Assyrian attacks, eventually being reduced to a province of the Middle Assyrian Empire . The Israelites were an ancient Semitic-speaking people of the Ancient Near East who inhabited part of Canaan during the tribal and monarchic periods (15th–6th centuries BC), and lived in the region in smaller numbers after

9322-636: The higher temperature required for smelting, 1,250 °C (2,280 °F), in addition to the greater difficulty of working with it, placed it out of reach of common use until the end of the 2nd millennium BC. Tin's lower melting point of 232 °C (450 °F) and copper's moderate melting point of 1,085 °C (1,985 °F) placed both these metals within the capabilities of Neolithic pottery kilns , which date to 6000 BC and were able to produce temperatures of at least 900 °C (1,650 °F). Copper and tin ores are rare since there were no tin bronzes in West Asia before trading in bronze began in

9440-450: The iron and carbon smelting must be kept in an oxygen-deficient (reducing) state to promote the burning of carbon to produce CO and not CO 2 . The inclusion of even small amounts of some elements can have profound effects on the behavioral characteristics of a batch of iron or the operation of a smelter. These effects can be both good and bad, some catastrophically bad. Some chemicals are deliberately added, such as flux, which makes

9558-413: The iron from the oxygen, a stronger elemental bond must be presented to attach to the oxygen. Carbon is used because the strength of a carbon-oxygen bond is greater than that of the iron-oxygen bond at high temperatures. Thus, the iron ore must be powdered and mixed with coke , to be burnt in the smelting process. Carbon monoxide is the primary ingredient of chemically stripping oxygen from iron. Thus,

9676-895: The iron is thought to have originated in dying stars that are large enough to explode as supernovae . The Earth's core is thought to consist mainly of iron, but this is inaccessible from the surface. Some iron meteorites are thought to have originated from asteroids 1,000 km (620 mi) in diameter or larger. Banded iron formations (BIFs) are sedimentary rocks containing more than 15% iron composed predominantly of thinly-bedded iron minerals and silica (as quartz ). Banded iron formations occur exclusively in Precambrian rocks, and are commonly weakly-to-intensely metamorphosed . Banded iron formations may contain iron in carbonates ( siderite or ankerite ) or silicates ( minnesotaite , greenalite , or grunerite ), but in those mined as iron ores, oxides ( magnetite or hematite ) are

9794-423: The magnetite concentrate. The size and strip ratio of most magnetite resources is irrelevant, as a banded iron formation can be hundreds of meters thick, extend hundreds of kilometers along strike , and can easily come to more than three billion or more tonnes of contained ore. The typical grade of iron at which a magnetite-bearing banded iron formation becomes economic is roughly 25% iron, which can generally yield

9912-476: The magnetite-bearing BIF or other rocks which form its main source, or protolith rock, but are considerably cheaper to mine and process as they require less beneficiation due to the higher iron content. However, DSO ores can contain significantly higher concentrations of penalty elements, typically being higher in phosphorus, water content (especially pisolite sedimentary accumulations), and aluminium ( clays within pisolites). Export-grade DSO ores are generally in

10030-399: The main iron ore producers ( BHP Billiton , Rio Tinto , and Vale S.A. ) and Japanese importers. In 2006, Chinese company Baosteel began handling negotiations for the importer side. The Chinese government replaced Baosteel with China Iron and Steel Association as lead negotiator in 2009. Traditionally, the first deal reached between these the major producers and the major importers sets

10148-410: The mine tailings contain an average of approximately 11% iron, there would be approximately 1.41 million tons of iron wasted annually. These tailings are also high in other useful metals such as copper , nickel , and cobalt , and they can be used for road-building materials like pavement and filler and building materials such as cement, low-grade glass, and wall materials. While tailings are

10266-617: The native Akkadian (Assyrian and Babylonian) population. The Aramaeans never had a unified empire; they were divided into independent kingdoms all across the Near East. After the Bronze Age collapse, their political influence was confined to Syro-Hittite states, which were entirely absorbed into the Neo-Assyrian Empire by the 8th century BC. The Mesopotamian Bronze Age began c.  3500 BC and ended with

10384-408: The numerous large sacrificial tripods known as dings ; there are many other distinct shapes. Surviving identified Chinese ritual bronzes tend to be highly decorated, often with the taotie motif, which involves stylised animal faces. These appear in three main motif types: those of demons, symbolic animals, and abstract symbols. Many large bronzes also bear cast inscriptions that are the bulk of

10502-698: The origins of agriculture. Foothill regions and glacial melt streams supported Bronze Age agro-pastoralists who developed complex east–west trade routes between Central Asia and China that introduced wheat and barley to China and millet to Central Asia. The Bactria–Margiana Archaeological Complex (BMAC), also known as the Oxus civilisation, was a Bronze Age civilisation in Central Asia, dated c.  2400  – c.  1600 BC , located in present-day northern Afghanistan , eastern Turkmenistan , southern Uzbekistan and western Tajikistan , centred on

10620-509: The past as high-grade iron ore deposits requiring little beneficiation . There are several granite-associated deposits of this nature in Malaysia and Indonesia . Other sources of magnetite iron ore include metamorphic accumulations of massive magnetite ore such as at Savage River , Tasmania , formed by shearing of ophiolite ultramafics . Another, minor, source of iron ores are magmatic accumulations in layered intrusions which contain

10738-588: The point of origin of a cultural enigma termed the Seima-Turbino Phenomenon . It is conjectured that changes in climate in this region c.  2000 BC }}, and the ensuing ecological, economic, and political changes, triggered a rapid and massive migration westward into northeast Europe, eastward into China, and southward into Vietnam and Thailand across a frontier of some 4,000 mi (6,000 km). This migration took place in just five to six generations and led to peoples from Finland in

10856-480: The principal Indian producers of iron ore. World consumption of iron ore grows 10% per year on average with the main consumers being China, Japan, Korea, the United States, and the European Union. China is currently the largest consumer of iron ore, which translates to be the world's largest steel producing country. It is also the largest importer, buying 52% of the seaborne trade in iron ore in 2004. China

10974-481: The principal iron mineral. Banded iron formations are known as taconite within North America. The mining involves moving tremendous amounts of ore and waste. The waste comes in two forms: non-ore bedrock in the mine ( overburden or interburden locally known as mullock), and unwanted minerals, which are an intrinsic part of the ore rock itself ( gangue ). The mullock is mined and piled in waste dumps , and

11092-429: The quartz is left behind when the resultant powder is passed under a magnetic separator. Generally, most magnetite banded iron formation deposits must be ground to between 32 and 45 μm (0.0013 and 0.0018 in) in order to produce a low-silica magnetite concentrate. Magnetite concentrate grades are generally in excess of 70% iron by weight and usually are low in phosphorus, aluminium, titanium, and silica and demand

11210-447: The rare finds is an idol of anthropomorphic form. The excavations of a Kurgan leader "demonstrate the complex cosmogonic idea, inherent in the architectural design of the mound. The city administration supports research archeologists around the city. As a logical extension of this work it is considering the establishment of a "Tumar" eco-cultural center as the pilot complex of tourist, educational, and ethnographic objects. According to

11328-531: The region laid the foundations for astronomy , mathematics, and astrology . The following dates are approximate. The Bronze Age in the Near East can be divided into Early, Middle and Late periods. The dates and phases below apply solely to the Near East, not universally. However, some archaeologists propose a "high chronology", which extends periods such as the Intermediate Bronze Age by 300 to 500–600 years, based on material analysis of

11446-473: The regional Bronze Age is the name given to the period in the 3rd millennium BC when Egyptian civilisation attained its first continuous peak of complexity and achievement—the first of three "Kingdom" periods which marked the high points of civilisation in the lower Nile Valley (the others being the Middle Kingdom and New Kingdom ). The First Intermediate Period of Egypt , often described as

11564-654: The rise of the Mesopotamian civilisation of Sumer in the mid-4th millennium BC. Cultures in the ancient Near East practised intensive year-round agriculture; developed writing systems ; invented the potter's wheel , created centralised governments (usually in the form of hereditary monarchies ), formulated written law codes, developed city-states , nation-states and empires; embarked on advanced architectural projects; and introduced social stratification , economic and civil administration, slavery , and practised organised warfare, medicine, and religion. Societies in

11682-539: The rise of the Shang and Zhou civilizations." According to Jan Romgard, "bronze and iron tools seem to have traveled from west to east as well as the use of wheeled wagons and the domestication of the horse." There are also possible links to Seima-Turbino culture , "a transcultural complex across northern Eurasia", the Eurasian steppe, and the Urals. However, the oldest bronze objects found in China so far were discovered at

11800-407: The rock must be comminuted to enable efficient magnetic separation to provide a high-purity magnetite concentrate. This determines the energy inputs required to run a milling operation. Mining of banded iron formations involves coarse crushing and screening, followed by rough crushing and fine grinding to comminute the ore to the point where the crystallized magnetite and quartz are fine enough that

11918-446: The seaborne trade, with 72% of the market. BHP, Rio and Vale control 66% of this market between them. In Australia , iron ore is won from three main sources: pisolite " channel iron deposit " ore derived by mechanical erosion of primary banded-iron formations and accumulated in alluvial channels such as at Pannawonica, Western Australia ; and the dominant metasomatically altered banded iron formation -related ores such as at Newman ,

12036-464: The seventh largest global center of iron ore production, behind Australia, Brazil, China, India, Russia, and South Africa. Producers of iron ore in Ukraine include Ferrexpo , Metinvest , and ArcelorMittal Kryvyi Rih . In 2014, mines in the United States produced 57,500,000 t (56,600,000 long tons; 63,400,000 short tons) of iron ore with an estimated value of $ 5.1 billion. Iron mining in

12154-451: The seventh-largest global center of iron ore production, behind Australia, Brazil, China, Russia, South Africa, and Ukraine. India's iron ore production in 2023 was 285,000,000 metric tonnes and was the fourth largest producer in the world. According to the U.S. Geological Survey's 2021 Report on iron ore, Ukraine is estimated to have produced 62,000,000 t (61,000,000 long tons; 68,000,000 short tons) of iron ore in 2020, placing it as

12272-706: The socket, which could be associated with the Seima-Turbino visual vocabulary of southern Siberia. The metallurgical centres of northwestern China, especially the Qijia culture in Gansu and Longshan culture in Shaanxi , played an intermediary role in this process. Iron use in China dates as early as the Zhou dynasty ( c.  1046  – 256 BC), but remained minimal. Chinese literature authored during

12390-517: The southern Korean Peninsula gradually adopted bronze production ( c.  700–600 BC ) after a period when Liaoning-style bronze daggers and other bronze artefacts were exchanged as far as the interior part of the Southern Peninsula ( c.  900–700 BC ). The bronze daggers lent prestige and authority to the personages who wielded and were buried with them in high-status megalithic burials at south-coastal centres such as

12508-474: The surviving body of early Chinese writing and have helped historians and archaeologists piece together the history of China, especially during the Zhou dynasty. The bronzes of the Western Zhou document large portions of history not found in the extant texts that were often composed by persons of varying rank and possibly even social class. Further, the medium of cast bronze lends the record they preserve

12626-401: The table aside. The major constraint to economics for iron ore deposits is not necessarily the grade or size of the deposits, because it is not particularly hard to geologically prove enough tonnage of the rocks exist. The main constraint is the position of the iron ore relative to market, the cost of rail infrastructure to get it to market, and the energy cost required to do so. Mining iron ore

12744-781: The two known as the Chalcolithic . The final decades of the Bronze Age in the Mediterranean basin are often characterised as a period of widespread societal collapse known as the Late Bronze Age collapse ( c.  1200  – c.  1150 BC ), although its severity and scope is debated among scholars. An ancient civilisation is deemed to be part of the Bronze Age if it either produced bronze by smelting its own copper and alloying it with tin , arsenic , or other metals, or traded other items for bronze from producing areas elsewhere. Bronze Age cultures were

12862-602: The two mines shut down. There have also been iron ore mines in Utah and Alabama ; however, the last iron ore mine in Utah shut down in 2014 and the last iron ore mine in Alabama shut down in 1975. Iron ores consist of oxygen and iron atoms bonded together into molecules. To convert it to metallic iron, it must be smelted or sent through a direct reduction process to remove the oxygen. Oxygen-iron bonds are strong, and to remove

12980-570: The upper Amu Darya (Oxus River). Its sites were discovered and named by the Soviet archaeologist Viktor Sarianidi (1976). Bactria was the Greek name for the area of Bactra (modern Balkh ), in what is now northern Afghanistan, and Margiana was the Greek name for the Persian satrapy of Marguš , the capital of which was Merv in present-day Turkmenistan. A wealth of information indicates that

13098-403: The west to Thailand in the east employing the same metalworking technology and, in some areas, horse breeding and riding. However, recent genetic testings of sites in south Siberia and Kazakhstan ( Andronovo horizon) would rather support spreading of the bronze technology via Indo-European migrations eastwards, as this technology had been well known for quite a while in western regions. It

13216-535: The written East Semitic Akkadian language for official use and as a spoken language. By that time, the Sumerian language was no longer spoken, but was still in religious use in Assyria and Babylonia, and would remain so until the 1st century AD. The Akkadian and Sumerian traditions played a major role in later Assyrian and Babylonian culture. Despite this, Babylonia, unlike the more militarily powerful Assyria,

13334-513: Was Egypt's most prosperous time and marked the peak of Egypt's power. The later New Kingdom, comprising the Nineteenth and Twentieth dynasties (1292–1069 BC), is also known as the Ramesside period , after the eleven pharaohs who took the name of Ramesses. Elam was a pre-Iranian ancient civilisation located east of Mesopotamia. In the Middle Bronze Age, Elam consisted of kingdoms on

13452-575: Was a historical period characterised principally by the use of bronze tools and the development of complex urban societies, as well as the adoption of writing in some areas. The Bronze Age is the middle principal period of the three-age system , following the Stone Age and preceding the Iron Age . Conceived as a global era, the Bronze Age follows the Neolithic , with a transition period between

13570-678: Was adopted in 1995. The emblem depicts a blue sky with the sun. Beneath it runs a fox - the symbol of the city. Under the fox is a dark brown stripe, blended with the frame. The emblem symbolizes the ground, fertile, rich in various minerals. Zip code - 111200 Schools of the city Lisakovsk constantly working 7 schools. 52°32′N 62°30′E  /  52.533°N 62.500°E  / 52.533; 62.500 Iron ore Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron

13688-475: Was buried in the Novoilinovsky-2 burial ground. The rider has a significant advantage over the infantryman. There may be another explanation: These elite fulfilled the function of mediating conflicts within the collective, and therefore had power and high social status. Metaphorically, this kind of elite can be called Sheriffs of the Bronze Age"  said Igor Chechushkov. The coat-of-arms of Lisakovsk

13806-466: Was founded by non-native Amorites and often ruled by other non-indigenous peoples such as the Kassites , Aramaeans and Chaldeans , as well as by its Assyrian neighbours. For many decades, scholars made superficial reference to Central Asia as the "pastoral realm" or alternatively, the "nomadic world", in what researchers call the "Central Asian void": a 5,000-year span that was neglected in studies of

13924-527: Was the western neighbour of the Middle and New Hittite Kingdoms , at times a rival and, at other times, a vassal. The Assuwa league was a confederation of states in western Anatolia defeated by the Hittites under the earlier Tudhaliya I c.  1400 BC . Arzawa has been associated with the more obscure Assuwa generally located to its north. It probably bordered it, and may have been an alternative term for it during some periods. In Ancient Egypt ,
