manganese "manganese deposits" "manganese minerals" "manganese ores" "Mn deposits" Manganese. Manganese is the ninth or tenth most abundant element in the Earth's crust . Most of its industrial use is in steel making with a much lesser amount going into the production of batteries. It is very similar to iron in its chemical properties.

The modern name "manganese" was derived from the 16 th century name for manganese dioxide, manganesum. The pigments from several colored manganese oxides, such as manganese dioxide, have been used by men since the Stone Age, as is the case in the Gargas cave paintings. These have been dated as 24,000 to 30,000 years old.

Manganese often results in a dense black stain or solid. For these reasons, it is recommended that drinking water have no more than 0.3 mg/L (or 0.3 parts per million) of iron and less than 0.05 mg/L of manganese. The U.S. Environmental Protection Agency has also set a Health Advisory for manganese of 0.3 mg/L.

The average manganese soil concentrations in the United States is 40–900 mg/kg; the primary natural source of the manganese is the erosion of crustal rock. Its presence in soil results in vegetable and animal foods reliably containing varying amounts of the mineral. As an essential nutrient, manganese …

The mining of manganese ore was a very important economic activity in Arkansas between 1849 and 1959. The region around Batesville (Independence County)—including about 100 square miles located in northwestern Independence County, southeastern Izard County, and northeastern Stone County—has produced more than ninety-eight percent of the manganese ore shipped from Arkansas. A second …

Manganese ores is confined to different rock types, belonging to both Khondalite and Charnockite groups, where they are dispersed throughout the country rocks as small lenses, pockets, veins and irregular bodies of varying dimensions. Quartz, garnet, clay, limonite and apatite are the common gangue minerals in the Manganese ores.

Manganese X Energy Corp. intends to provide a secure ethically sourced manganese supply by exploring and developing its manganese rich deposit near Woodstock New Brunswick, the Battery Hill Project. The Fraser Institute has recently called New Brunswick one of the best mining jurisdiction in Canada, a country known to be mining friendly.

Elemental manganese readily combines with oxygen, carbon, and silicon to form a long list of manganese minerals. Manganese ores generally contain 25 to 45 percent manganese, mostly in oxide (or hydroxide) and carbonate minerals. Such ores are widespread, but most of the world's supply is from a small number of manganese mining districts.

Manganese rock by composition is represented by two subgroups of the chemical and biochemical group of sedimentary rocks (Frolov, 1964a,b)—carbonate and oxide (manganolites). Manganolites represent sedimentary rocks and ores, the predominant component of which are oxides and hydroxides of manganese (Geologicheskii slovar', 1973.

Manganese steel is commonly used in the mining industry (cement mixers, rock crushers, crawler treads for tractors), rail industry (railway switches and crossings), window bars in prisons, safes, bullet-proof cabinets, anti-drill plates, metal recycling, and other high impact environments like inside a shot peening machine.

Austenitic manganese steel – steel alloyed with more than 10% manganese – is work-hardening. That means that high impacts – like those in a crushing chamber for example – cause the formation of a extremely hard surface layer that is two to three times harder than the rest of the alloy If impacted enough, this results in a hard exterior layer backed by a softer core.
