87-763: It was created on 1 July 2008 with the merging of the Swedish Nuclear Power Inspectorate and the Swedish Radiation Protection Authority . It employs 300 people and is located in Stockholm, with an annual budget of about 400 million Swedish krona . Its Director-General is Nina Cromnier . On the first of March 2022, the Swedish Radiation Safety Authority increased their readiness to handle an "radiological emergency" in

174-491: A matte for further refining. Hydrometallurgical techniques are also used. Most sulfide deposits have traditionally been processed by concentration through a froth flotation process followed by pyrometallurgical extraction. The nickel matte is further processed with the Sherritt-Gordon process . First, copper is removed by adding hydrogen sulfide , leaving a concentrate of cobalt and nickel. Then, solvent extraction

261-430: A 20-kronor note was introduced. All remaining one krona banknotes became invalid after 31 December 1987. All remaining five krona and ten krona banknotes became invalid after 31 December 1998. An exhaustive list of every banknote design since 1874 is not included, but the following five designs were or will be retired in 2016–2017. The oldest design began to be printed in 1985. A 20-kronor banknote (a new denomination)

348-399: A compound, nickel has a number of niche chemical manufacturing uses, such as a catalyst for hydrogenation , cathodes for rechargeable batteries, pigments and metal surface treatments. Nickel is an essential nutrient for some microorganisms and plants that have enzymes with nickel as an active site . Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It

435-464: A new series of coins with new sizes to replace the 1-krona and 5-kronor coins; the new coins arrived in October 2016. The design of the coins follows the theme of singer-songwriter Ted Gärdestad 's song, " Sol, vind och vatten " (English: "Sun, wind and water"), with the designs depicting the elements on the reverse side of the coins. This also included the reintroduction of the 2-kronor coin, while

522-407: A per capita basis, are reduced by 51% from the high in 2007 compared to 2018. Speculation about Sweden declaring all banknotes and coins invalid at some future date is widespread in the media with Björn Ulvaeus as a celebrity advocate of a cashless Sweden which he believes will result in a safer society because simple robbery will involve stealing goods that must be fenced. Nickel Nickel

609-401: A portrait of the singer Jenny Lind and on the reverse was a picture of a silver harp and its tonal range. The banknote became invalid after 31 December 2013. A more secure version with the same portrait was printed from 2006 to 2011 and became invalid after 30 June 2016. A 100-kronor banknote (3rd design since 1898) was printed 1986–2000 with a portrait of the botanist Carl Linnaeus and on

696-713: A public controversy regarding the problems of people with nickel allergy . An estimated 3.6 million tonnes (t) of nickel per year are mined worldwide; Indonesia (1,800,000 t), the Philippines (400,000 t), Russia (200,000 t), New Caledonia ( France ) (230,000 t), Canada (180,000 t) and Australia (160,000 t) are the largest producers as of 2023. The largest nickel deposits in non-Russian Europe are in Finland and Greece . Identified land-based sources averaging at least 1% nickel contain at least 130 million tonnes of nickel. About 60%

783-417: A reasonable smallest denomination coin was 1 öre. A 10 kr gold coin weighed 4.4803 grams with 900 fineness so that the fine weight was 4.03327 grams or exactly 1/248th of a kilogram. In 1902, production of gold coins ceased, and was briefly restarted in 1920 and 1925 before ceasing entirely. Due to metal shortages during World War I , iron replaced bronze between 1917 and 1919. Nickel-bronze replaced silver in

870-621: A significant percentage. According to Bank for International Settlements the last year Sweden was surpassed in cash on a per capita basis converted to United States dollars by the US in 1993, the Euro Area in 2003, Australia in 2007, Canada in 2009, United Kingdom and Saudi Arabia in 2013, South Korea in 2014, Russia in 2016, and Mexico in 2019. As of 2019 Sweden was still circulating more cash per person (converted to USD) than Argentina, Brazil, Turkey, India, Indonesia, and South Africa. The tables show

957-504: Is Ni with 28 protons and 50 neutrons. Both are therefore unusually stable for nuclei with so large a proton–neutron imbalance . Nickel-63 is a contaminant found in the support structure of nuclear reactors. It is produced through neutron capture by nickel-62. Small amounts have also been found near nuclear weapon test sites in the South Pacific. Nickel ores are classified as oxides or sulfides. Oxides include laterite , where

1044-411: Is $ 0.045 (90% of the face value). In the 21st century, the high price of nickel has led to some replacement of the metal in coins around the world. Coins still made with nickel alloys include one- and two- euro coins , 5¢, 10¢, 25¢, 50¢, and $ 1 U.S. coins , and 20p, 50p, £1, and £2 UK coins . From 2012 on the nickel-alloy used for 5p and 10p UK coins was replaced with nickel-plated steel. This ignited

1131-427: Is a chemical element ; it has symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal . Pure nickel is chemically reactive, but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel

1218-417: Is a 3d 4s energy level, specifically the 3d ( F) 4s F, J  = 4 level. However, each of these two configurations splits into several energy levels due to fine structure , and the two sets of energy levels overlap. The average energy of states with [Ar] 3d 4s is actually lower than the average energy of states with [Ar] 3d 4s . Therefore, the research literature on atomic calculations quotes

1305-486: Is a legally-enforced method of rounding off change, up or down, to the nearest unit of physical currency, while retaining the öre as pricing and accounting unit. It was required in conjunction with the phaseout of smaller coins, as follows: In 1971 the 2-kronor coin ceased production. In 1972 the sizes of the 5-öre and 5-kronor coins were reduced. In 1991, aluminium-brass (" Nordic gold ") 10-kronor coins were introduced; previous 10-kronor coins are not legal tender. In

1392-725: Is a new nickel mine in Michigan's Upper Peninsula . Construction was completed in 2013, and operations began in the third quarter of 2014. In the first full year of operation, the Eagle Mine produced 18,000 t. Nickel is obtained through extractive metallurgy : it is extracted from ore by conventional roasting and reduction processes that yield metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on impurities. Traditionally, most sulfide ores are processed using pyrometallurgical techniques to produce

1479-501: Is a volatile, highly toxic liquid at room temperature. On heating, the complex decomposes back to nickel and carbon monoxide: This behavior is exploited in the Mond process for purifying nickel, as described above. The related nickel(0) complex bis(cyclooctadiene)nickel(0) is a useful catalyst in organonickel chemistry because the cyclooctadiene (or cod ) ligands are easily displaced. Nickel(I) complexes are uncommon, but one example

1566-703: Is currently being set in place by the International Seabed Authority to ensure that these nodules are collected in an environmentally conscientious manner while adhering to the United Nations Sustainable Development Goals . The one place in the United States where nickel has been profitably mined is Riddle, Oregon , with several square miles of nickel-bearing garnierite surface deposits. The mine closed in 1987. The Eagle mine project

1653-601: Is found in Earth's crust only in tiny amounts, usually in ultramafic rocks , and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron , a reflection of the origin of those elements as major end products of supernova nucleosynthesis . An iron–nickel mixture is thought to compose Earth's outer and inner cores . Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel

1740-605: Is gained from the people and all the major parties. Therefore, the timing is now at the discretion of the Social Democrats . He added, the request of Mona Sahlin , former leader of the Social Democratic Party, for deferral of a new referendum until after the 2010 mandate period should be respected. As of 2014 , support for Swedish membership of the euro among the general population is low. In September 2013, support fell as low as 9%. The only party in

1827-470: Is greater than both Fe and Fe , more abundant nuclides often incorrectly cited as having the highest binding energy. Though this would seem to predict nickel as the most abundant heavy element in the universe, the high rate of photodisintegration of nickel in stellar interiors causes iron to be by far the most abundant. Nickel-60 is the daughter product of the extinct radionuclide Fe (half-life 2.6 million years). Due to

1914-575: Is in laterites and 40% is in sulfide deposits. Also, extensive nickel sources are found in the depths of the Pacific Ocean , especially in an area called the Clarion Clipperton Zone in the form of polymetallic nodules peppering the seafloor at 3.5–6 km below sea level . These nodules are composed of numerous rare-earth metals and are estimated to be 1.7% nickel. With advances in science and engineering , regulation

2001-455: Is now Syria have been found to contain as much as 2% nickel. Some ancient Chinese manuscripts suggest that "white copper" ( cupronickel , known as baitong ) was used there in 1700–1400 BCE. This Paktong white copper was exported to Britain as early as the 17th century, but the nickel content of this alloy was not discovered until 1822. Coins of nickel-copper alloy were minted by Bactrian kings Agathocles , Euthydemus II , and Pantaleon in

2088-434: Is now known as the mineral nickeline (formerly niccolite ), a nickel arsenide . In 1751, Baron Axel Fredrik Cronstedt tried to extract copper from kupfernickel at a cobalt mine in the village of Los, Sweden , and instead produced a white metal that he named nickel after the spirit that had given its name to the mineral. In modern German, Kupfernickel or Kupfer-Nickel designates the alloy cupronickel . Originally,

2175-412: Is one of only four elements that are ferromagnetic at or near room temperature; the others are iron, cobalt and gadolinium . Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature. The unit cell of nickel is a face-centered cube ; it has lattice parameter of 0.352 nm, giving an atomic radius of 0.124 nm. This crystal structure

2262-469: Is produced by the silicon burning process and later set free in large amounts in type Ia supernovae . The shape of the light curve of these supernovae at intermediate to late-times corresponds to the decay via electron capture of Ni to cobalt -56 and ultimately to iron-56. Nickel-59 is a long-lived cosmogenic radionuclide ; half-life 76,000 years. Ni has found many applications in isotope geology . Ni has been used to date

2349-407: Is required to join the eurozone and therefore must convert to the euro once the convergence criteria are met. Notwithstanding this, on 14 September 2003, a consultative Swedish referendum was held on the euro, in which 56% of voters were opposed to the adoption of the currency, out of an overall turnout of 82.6%. The Swedish government has argued such a course of action is possible since one of

2436-572: Is stable to pressures of at least 70 GPa. Nickel is hard, malleable and ductile , and has a relatively high electrical and thermal conductivity for transition metals. The high compressive strength of 34 GPa, predicted for ideal crystals, is never obtained in the real bulk material due to formation and movement of dislocations . However, it has been reached in Ni nanoparticles . Nickel has two atomic electron configurations , [Ar] 3d 4s and [Ar] 3d 4s , which are very close in energy; [Ar] denotes

2523-446: Is the tetrahedral complex NiBr(PPh 3 ) 3 . Many nickel(I) complexes have Ni–Ni bonding, such as the dark red diamagnetic K 4 [Ni 2 (CN) 6 ] prepared by reduction of K 2 [Ni 2 (CN) 6 ] with sodium amalgam . This compound is oxidized in water, liberating H 2 . It is thought that the nickel(I) oxidation state is important to nickel-containing enzymes, such as [NiFe]-hydrogenase , which catalyzes

2610-479: Is used as the cathode in many rechargeable batteries , including nickel–cadmium , nickel–iron , nickel–hydrogen , and nickel–metal hydride , and used by certain manufacturers in Li-ion batteries . Ni(IV) remains a rare oxidation state and very few compounds are known. Ni(IV) occurs in the mixed oxide BaNiO 3 . Unintentional use of nickel can be traced back as far as 3500 BCE. Bronzes from what

2697-455: Is used chiefly in alloys and corrosion-resistant plating. About 68% of world production is used in stainless steel . A further 10% is used for nickel-based and copper-based alloys, 9% for plating, 7% for alloy steels, 3% in foundries, and 4% in other applications such as in rechargeable batteries, including those in electric vehicles (EVs). Nickel is widely used in coins , though nickel-plated objects sometimes provoke nickel allergy . As

2784-412: Is used to separate the cobalt and nickel, with the final nickel content greater than 86%. A second common refining process is leaching the metal matte into a nickel salt solution, followed by electrowinning the nickel from solution by plating it onto a cathode as electrolytic nickel. The purest metal is obtained from nickel oxide by the Mond process , which gives a purity of over 99.99%. The process

2871-469: The Riksbank in denominations of 1 krona and 5, 10, 50, 100 and 1,000 kronor. The 1 krona was only initially issued for two years, although it reappeared between 1914 and 1920. In 1939 and 1958, 10,000-kronor notes were issued. Production of the 5-kronor note ceased in 1981, although a coin had been issued since 1972. With the introduction of a 10-krona coin in 1991, production of 10-kronor notes ceased and

2958-703: The Riksdag formally decided to enact the law to abolish 50-öre coins as legal tender. Under that law, the final date payments could be made with 50-öre coins was 30 September 2010. Remaining 50-öre coins could be exchanged at banks until the end of March 2011. After the launch of the current coin series in 2016, all the old kronor coins have been invalid since 2017. They cannot be used for payments, nor can they be exchanged for legal tender at any bank, and are instead instructed to be recycled as metal. Jubilee and commemorative coins have been minted, and those since 1897 are also legal tender. In 1874, notes were introduced by

3045-496: The Riksdag that supports Swedish entry in the euro (as of 2015) is the Liberal Party . Sweden is a wealthy country and in the 1970s and 1980s the value of banknotes and coins per capita was one of the highest in the world. In 1991, the largest banknote worth 10,000kr that was in circulation since 1958 was declared invalid and no longer was legal tender. For a discussion of the financial and banking crisis that hit Sweden in

3132-467: The arsenide niccolite . Identified land-based resources throughout the world averaging 1% nickel or greater comprise at least 130 million tons of nickel (about the double of known reserves). About 60% is in laterites and 40% in sulfide deposits. On geophysical evidence, most of the nickel on Earth is believed to be in Earth's outer and inner cores . Kamacite and taenite are naturally occurring alloys of iron and nickel. For kamacite,

3219-522: The gold standard , with the krona/krone defined as 1 ⁄ 2480 of a kilogram of pure gold. The mutual equivalence of all three currencies ended in World War I when their convertibility to gold was suspended. While their gold parities remained during most of the interwar period, these currencies were generally quoted at varying market rates. On 11   September 2012, the Riksbank announced

3306-484: The metal aquo complex [Ni(H 2 O) 6 ] . The four halides form nickel compounds, which are solids with molecules with octahedral Ni centres. Nickel(II) chloride is most common, and its behavior is illustrative of the other halides. Nickel(II) chloride is made by dissolving nickel or its oxide in hydrochloric acid . It is usually found as the green hexahydrate, whose formula is usually written NiCl 2 ·6H 2 O . When dissolved in water, this salt forms

3393-479: The metal aquo complex [Ni(H 2 O) 6 ] . Dehydration of NiCl 2 ·6H 2 O gives yellow anhydrous NiCl 2 . Some tetracoordinate nickel(II) complexes, e.g. bis(triphenylphosphine)nickel chloride , exist both in tetrahedral and square planar geometries. The tetrahedral complexes are paramagnetic ; the square planar complexes are diamagnetic . In having properties of magnetic equilibrium and formation of octahedral complexes, they contrast with

3480-476: The 10, 25 and 50 öre in 1920, with silver returning in 1927. Metal shortages due to World War II again led to changes in the Swedish coinage. Between 1940 and 1947, the nickel-bronze 10, 25 and 50 öre were again issued. In 1942, iron again replaced bronze (until 1952) and the silver content of the other coins was reduced. In 1962, cupronickel replaced silver in the 10-öre, 25-öre and 50-öre coins. In 1968,

3567-530: The 10, 25, 50 öre and 1 krona and 2 kronor were in silver, and the 10 and 20 kronor were in gold. Gold 5-kronor coins were added in 1881. In 1873 the Scandinavian Monetary Union currency was fixed so that 2,480 kronor purchased 1 kg of gold. In 2017 the price of gold is 365,289 kronor per kg. So one öre in 1873 bought as much gold as 1.47 kronor in 2017. So if it is reasonable to have the smallest denomination coin 1 krona today, in 1873

3654-473: The 10,000-kronor banknotes a new 1,000-kronor banknotes (of the 4th design / without foil strips) was printed from 1989 to 1991 with a portrait of Gustav Vasa and on the reverse a harvest picture from Olaus Magnus 's Description of the Northern Peoples from 1555. Circulation peaked at over 48 million in 2001. On 15 March 2006, the Riksbank introduced a new, more secure 1,000-kronor banknote with

3741-563: The 2-kronor switched to cupronickel and the 1-krona switched to cupronickel-clad copper (it was replaced entirely by cupronickel in 1982). Nonetheless, all previous mintages of the 1-krona (since 1875) and 2-kronor (since 1876) were still legal tender until 2017, though 2-kronor coins were extremely rarely seen in circulation as they have not been issued since 1971. The 2-kronor coins contained 40% silver until 1966, which meant they had been for several years worth much more than face value, so most have been bought and melted down by arbitrageurs , and

3828-543: The 2nd century BCE, possibly out of the Chinese cupronickel. In medieval Germany, a metallic yellow mineral was found in the Ore Mountains that resembled copper ore. But when miners were unable to get any copper from it, they blamed a mischievous sprite of German mythology, Nickel (similar to Old Nick ), for besetting the copper. They called this ore Kupfernickel from German Kupfer 'copper'. This ore

3915-647: The Kingdom of Sweden . It is one of the currencies of the European Union . Both the ISO code "SEK" and currency sign "kr" are in common use for the krona; the former precedes or follows the value, the latter usually follows it but, especially in the past, it sometimes preceded the value. In English, the currency is sometimes referred to as the Swedish crown , as krona means " crown " in Swedish. The Swedish krona

4002-643: The Nazi era, and the association is that Hitler liked his music. The Riksbank replied saying that it is "unfortunate that the choice of design is seen as negative", and stated that it is not going to be changed. Dagens Nyheter journalist Björn Wiman went further in his criticism, condemning the Riksbank for selecting Nilsson at all for the 500-kronor banknote. He brings up an example from Nilsson's 1995 autobiography, where she described Mauritz Rosengarten from Decca using antisemitic jokes about greed. To see where Swedish krona ranks in "most traded currencies", read

4089-453: The Riksbank announced the names of the persons whose portraits would decorate the new series of banknotes that would be introduced in 2015. This would also include a new 200-kronor banknote. These are: On 24   April 2012, the Riksbank announced the base for the new designs of the banknotes, based on Göran Österlund's entry titled Cultural Journey . The first banknotes, the 20, 50, 200, and 1,000 krona, were issued on 1 October 2015 with

4176-504: The United States, the term "nickel" or "nick" originally applied to the copper-nickel Flying Eagle cent , which replaced copper with 12% nickel 1857–58, then the Indian Head cent of the same alloy from 1859 to 1864. Still later, in 1865, the term designated the three-cent nickel , with nickel increased to 25%. In 1866, the five-cent shield nickel (25% nickel, 75% copper) appropriated the designation, which has been used ever since for

4263-501: The alloy is usually in the proportion of 90:10 to 95:5, though impurities (such as cobalt or carbon ) may be present. Taenite is 20% to 65% nickel. Kamacite and taenite are also found in nickel iron meteorites . Nickel is commonly found in iron meteorites as the alloys kamacite and taenite . Nickel in meteorites was first detected in 1799 by Joseph-Louis Proust , a French chemist who then worked in Spain. Proust analyzed samples of

4350-454: The article on the Foreign exchange market . The exchange rate of the Swedish krona against other currencies has historically been dependent on the monetary policy pursued by Sweden at the time. Since the Swedish banking rescue , a managed float regimen has been upheld. The weakest the krona has been relative to the euro was 6 March 2009 when one euro bought 11.6465 SEK. The strongest

4437-469: The complete argon core structure. There is some disagreement on which configuration has the lower energy. Chemistry textbooks quote nickel's electron configuration as [Ar] 4s 3d , also written [Ar] 3d 4s . This configuration agrees with the Madelung energy ordering rule , which predicts that 4s is filled before 3d. It is supported by the experimental fact that the lowest energy state of the nickel atom

4524-517: The current 10-kronor coin remained the same. The new coins also have a new portrait of the king in their design. One of the reasons for a new series of coins was to end the use of nickel (for allergy reasons). Vending machines and parking meters have to a fairly high degree stopped accepting coins and accept only bank cards or mobile phone payments . Between 1873 and 1876, coins in denominations of 1, 2, 5, 10, 25, and 50 öre and 1, 2, 10, and 20 kronor were introduced. The 1, 2 and 5 öre were in bronze,

4611-484: The divalent complexes of the heavier group 10 metals, palladium(II) and platinum(II), which form only square-planar geometry. Nickelocene has an electron count of 20. Many chemical reactions of nickelocene tend to yield 18-electron products. Many Ni(III) compounds are known. Ni(III) forms simple salts with fluoride or oxide ions. Ni(III) can be stabilized by σ-donor ligands such as thiols and organophosphines . Ni(III) occurs in nickel oxide hydroxide , which

4698-408: The early 1990s see the article History of Sweden (1991–present) and Swedish banking rescue . Unlike the United States, which by policy never declares issued money invalid, Sweden and most other European countries have a date when older series of banknotes or older coin designs are invalid and are no longer legal tender. Invalid old banknotes of any age can, however, be deposited in the Riksbank, and

4785-701: The earth's crust exists as oxides, economically more important nickel ores are sulfides, especially pentlandite . Major production sites include the Sudbury region , Canada (which is thought to be of meteoric origin), New Caledonia in the Pacific , Western Australia , and Norilsk , Russia. Nickel is one of four elements (the others are iron , cobalt , and gadolinium ) that are ferromagnetic at about room temperature. Alnico permanent magnets based partly on nickel are of intermediate strength between iron-based permanent magnets and rare-earth magnets . The metal

4872-479: The ground state configuration as [Ar] 3d 4s . The isotopes of nickel range in atomic weight from 48  u ( Ni ) to 82 u ( Ni ). Natural nickel is composed of five stable isotopes , Ni , Ni , Ni , Ni and Ni , of which Ni is the most abundant (68.077% natural abundance ). Nickel-62 has the highest binding energy per nucleon of any nuclide : 8.7946 MeV/nucleon. Its binding energy

4959-544: The krona has been relative to the euro was on 13 August 2012 when one euro bought 8.2065 SEK. The weakness in the euro was due to the crisis in Greece which began in July 2012 and fear of further spreading to Italy and Spain. The average exchange rate since the beginning of 2002 when the euro banknote and coins were issued and 1 March 2017 was 9.2884 SEK/EUR. According to the 1994 accession treaty (effective 1 January 1995), Sweden

5046-750: The large deposits in the Sudbury Basin in Canada in 1883, in Norilsk -Talnakh in Russia in 1920, and in the Merensky Reef in South Africa in 1924 made large-scale nickel production possible. Aside from the aforementioned Bactrian coins, nickel was not a component of coins until the mid-19th century. 99.9% nickel five-cent coins were struck in Canada (the world's largest nickel producer at

5133-784: The long half-life of Fe , its persistence in materials in the Solar System may generate observable variations in the isotopic composition of Ni . Therefore, the abundance of Ni in extraterrestrial material may give insight into the origin of the Solar System and its early history. At least 26 nickel radioisotopes have been characterized; the most stable are Ni with half-life 76,000 years, Ni (100 years), and Ni (6 days). All other radioisotopes have half-lives less than 60 hours and most these have half-lives less than 30 seconds. This element also has one meta state . Radioactive nickel-56

5220-416: The metals at a profit. The United States Mint , anticipating this practice, implemented new interim rules on December 14, 2006, subject to public comment for 30 days, which criminalized the melting and export of cents and nickels. Violators can be punished with a fine of up to $ 10,000 and/or a maximum of five years in prison. As of September 19, 2013, the melt value of a US nickel (copper and nickel included)

5394-467: The monarch is also inscribed on many of the coins. A new 5-kronor coin was designed in 1974, at a time when there were political efforts to abandon the monarchy and the young inexperienced king. The monarchy remained, but the 5-kronor was not given a portrait. Coins minted before 1974 have the same size, but contain the portrait of King Gustav VI Adolf and his royal motto. Cash rounding (Swedish: öresavrundning ), commonly called Swedish rounding ,

5481-450: The most valuable banknotes in the world. The first design featuring the Head of Mercury was printed in 1939 and became invalid after 31 December 1987.

The parties to the union were the Scandinavian countries, where the name was krona in Sweden and krone in Denmark and Norway , which in English literally means "crown". The three currencies were on

5655-509: The only source for nickel was the rare Kupfernickel. Beginning in 1824, nickel was obtained as a byproduct of cobalt blue production. The first large-scale smelting of nickel began in Norway in 1848 from nickel-rich pyrrhotite . The introduction of nickel in steel production in 1889 increased the demand for nickel; the nickel deposits of New Caledonia , discovered in 1865, provided most of the world's supply between 1875 and 1915. The discovery of

In this process, nickel is treated with carbon monoxide in the presence of a sulfur catalyst at around 40–80 °C to form nickel carbonyl . In a similar reaction with iron, iron pentacarbonyl can form, though this reaction is slow. If necessary, the nickel may be separated by distillation. Dicobalt octacarbonyl
