Manganese isotopic contents are typically combined with chromium isotopic contents and have found application in isotope geology and radiometric dating . Mn–Cr isotopic ratios reinforce the evidence from Al and Pd for the early history of the Solar System . Variations in Cr/ Cr and Mn/Cr ratios from several meteorites suggest an initial Mn/ Mn ratio, which indicate that Mn–Cr isotopic composition must result from in situ decay of Mn in differentiated planetary bodies. Hence, Mn provides additional evidence for nucleosynthetic processes immediately before coalescence of

This geographical entity likely constituted a component of the ancient Khijjinga territory, which had its headquarters at Khijjinga Kota, now identified as modern Khiching . It evolved into an independent state during the early half of the 12th century A.D., under the rulership of Jyoti Bhanja. Preceding the reign of Jyoti Bhanja, Kendujhar's territorial jurisdiction encompassed solely
10112-655: The famed king cobra , plus banded krait and tricarinate hill turtle . There is also a mugger crocodile breeding programme in nearby Ramtirtha. The Chandaka Elephant Sanctuary is a 190 km protected area near the capital city, Bhubaneswar. However, urban expansion and over-grazing have reduced the forests, driving the herds of elephants to migrate away, as well as increasing human-elephant conflicts—which sometimes results in injury and death (on both sides). Some elephants have died in conflicts with villagers, while some have died during migration after being accidentally electrocuted by power lines or even hit by trains. Outside
10240-491: The form of ferrocene ( Fe(C 5 H 5 ) 2 ). When conducted under an atmosphere of carbon monoxide , reduction of Mn(II) salts gives dimanganese decacarbonyl Mn 2 (CO) 10 , an orange and volatile solid. The air-stability of this Mn(0) compound (and its many derivatives) reflects the powerful electron-acceptor properties of carbon monoxide. Many alkene complexes and alkyne complexes are derived from Mn 2 (CO) 10 . In Mn(CH 3 ) 2 (dmpe) 2 , Mn(II)

The embrittlement decreases at higher manganese concentrations and reaches an acceptable level at 8%. Steel containing 8 to 15% of manganese has a high tensile strength of up to 863 MPa. Steel with 12% manganese was discovered in 1882 by Robert Hadfield and is still known as Hadfield steel (mangalloy) . It
10880-503: The manganese ore to manganese oxide (MnO), which is a leachable form. The ore then travels through a grinding circuit to reduce the particle size of the ore to between 150 and 250 μm, increasing the surface area to aid leaching. The ore is then added to a leach tank of sulfuric acid and ferrous iron (Fe ) in a 1.6:1 ratio. The iron reacts with the manganese dioxide (MnO 2 ) to form iron hydroxide (FeO(OH)) and elemental manganese (Mn). This process yields approximately 92% recovery of
11008-460: The manganese. For further purification, the manganese can then be sent to an electrowinning facility. In 1972, the CIA 's Project Azorian , through billionaire Howard Hughes , commissioned the ship Hughes Glomar Explorer with the cover story of harvesting manganese nodules from the sea floor. That triggered a rush of activity to collect manganese nodules, which was not actually practical until
11136-633: The metal, but that is uncertain. By the mid-18th century, the Swedish chemist Carl Wilhelm Scheele used manganese dioxide to produce chlorine . First, hydrochloric acid , or a mixture of dilute sulfuric acid and sodium chloride was made to react with manganese dioxide, and later hydrochloric acid from the Leblanc process was used and the manganese dioxide was recycled by the Weldon process . The production of chlorine and hypochlorite bleaching agents

Manganese is part of the iron group of elements, which are thought to be synthesized in large stars shortly before the supernova explosion. Mn decays to Cr with a half-life of 3.7 million years. Because of its relatively short half-life, Mn
11648-501: The mountaintops appear to be sharply ridged or peaked, however they have extensive tablelands on their summits.

It also extended from Mayurbhanj in the east to the perimeters of the States of Bonai , Pal-lahara , and Dhenkanal in
12032-524: The ocean from river inputs. Surface dMn concentrations can also be elevated biologically through photosynthesis and physically from coastal upwelling and wind-driven surface currents. Internal cycling such as photo-reduction from UV radiation can also elevate levels by speeding up the dissolution of Mn-oxides and oxidative scavenging, preventing Mn from sinking to deeper waters. Elevated levels at mid-depths can occur near mid-ocean ridges and hydrothermal vents. The hydrothermal vents release dMn enriched fluid into

The invention of the Leclanché cell in 1866 and the subsequent improvement of batteries containing manganese dioxide as cathodic depolarizer increased the demand for manganese dioxide. Until the development of batteries with nickel–cadmium and lithium, most batteries contained manganese. The zinc–carbon battery and the alkaline battery normally use industrially produced manganese dioxide because naturally occurring manganese dioxide contains impurities. In

The state also has bamboo forests (10,518 km ) and tidal areas of mangrove swamp (221 km ). The state
15488-482: Was a large consumer of manganese ores. Scheele and others were aware that pyrolusite (mineral form of manganese dioxide) contained a new element. Johan Gottlieb Gahn isolated an impure sample of manganese metal in 1774, which he did by reducing the dioxide with carbon . The manganese content of some iron ores used in Greece led to speculations that steel produced from that ore contains additional manganese, making

16000-412: Was the eighth year of his reign. According to his own edicts , in that war about 100,000 people were killed, 150,000 were captured and more were affected. The resulting bloodshed and suffering of the war is said to have deeply affected Ashoka. He turned into a pacifist and converted to Buddhism. By c. 150 BCE, Emperor Kharavela , who was possibly a contemporary of Demetrius I of Bactria , conquered
16128-572: Was used for British military steel helmets and later by the U.S. military. Manganese is used in production of alloys with aluminium. Aluminium with roughly 1.5% manganese has increased resistance to corrosion through grains that absorb impurities which would lead to galvanic corrosion . The corrosion-resistant aluminium alloys 3004 and 3104 (0.8 to 1.5% manganese) are used for most beverage cans . Before 2000, more than 1.6 million tonnes of those alloys were used; at 1% manganese, this consumed 16,000 tonnes of manganese. Manganese(IV) oxide
16256-414: Was used in the original type of dry cell battery as an electron acceptor from zinc, and is the blackish material in carbon–zinc type flashlight cells. The manganese dioxide is reduced to the manganese oxide-hydroxide MnO(OH) during discharging, preventing the formation of hydrogen at the anode of the battery. The same material also functions in newer alkaline batteries (usually battery cells), which use
16384-438: Was used to decolorize glass. This female magnes was later called magnesia , known now in modern times as pyrolusite or manganese dioxide . Neither this mineral nor elemental manganese is magnetic. In the 16th century, manganese dioxide was called manganesum (note the two Ns instead of one) by glassmakers, possibly as a corruption and concatenation of two words, since alchemists and glassmakers eventually had to differentiate
