Manganese: Manganese may be proved as follows: A few grains of powdered ore are placed in a test-tube, with three or four drops of sulfuric acid. Two or three grains of granulated lead or litharge being dropped in, the color will become pink should manganese be in the ore.
Exposure to manganese dust occurs primarily in mining, ore-crushing, and metallurgical operations for iron, steel, ferrous and nonferrous alloys. Manufacturing of dry-cell batteries, anti-knock gasoline additives, pesticides (e.g. maneb), pigments, dyes, inks and incendiary devices can also lead to occupational manganese exposure.
Although manganese is an essential nutrient, exposure to high levels via inhalation or ingestion may cause some adverse health effects. It has been suggested that these adverse health effects, especially neurologic effects, are occurring on a "continuum of …dysfunction" that is dose-related (Mergler et al. 1999). In other words, mild or ...

Most manganese is mined in open pit or shallow underground mines. More than 80% of the high-grade manganese ore (>35% manganese) is mined in South Africa, and also Australia, Brazil, Gabon, and, India, and, more recently, China, and the Commonwealth of Independent States (CIS).
Manganese-rich ore resources are mainly concentrated in South Africa, Gabon, Brazil and Australia. For example, the Kalahari mine in South Africa has a manganese ore grade of 30-50 percent, the Groote Eylandt mine in Australia has a manganese ore grade of 40-50 percent, and India, Kazakhstan and Mexico are medium-grade manganese resource countries.
General description This Spectroquant Manganese Reagent Test allows the accurate quantification of the concentration of all manganese ion species in aqueous samples.

The genetic types and classification of manganese-ore deposits with model examples of manganese-ore deposits on the base of isotope data, geochemistry, and geology structure were suggested: sedimentary-diagenetic deposits of sedimentary-rock basins (Nikopol manganese-ore basin, Ukraine; ...
Polymetallic nodules, also called manganese nodules, are rock concretions on the sea bottom formed of concentric layers of iron and manganese hydroxides around a core. As nodules can be found in vast quantities, and contain valuable metals, deposits have been identified as having economic interest.
For low manganese levels in the body (manganese deficiency): For preventing manganese deficiency in children, total parenteral nutrition containing 2-10 mcg or up to 50 mcg of elemental manganese ...

The problem involved in Manganese Ore Processing deals with the production of acceptable specification grades of manganese concentrates at a maximum recovery of the total manganese from ores having variable characteristics. The flowsheet provides for both gravity and flotation with a maximum recovery of the manganese values in a coarse size in the most economical manner by the use of jigs …
Manganese is a chemical element with the symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron.Manganese is a transition metal with important industrial alloy uses, particularly in stainless steels.
Manganese (Mn) is a hard, gray metal that is frequently used in the production of steel. Workers may be harmed from exposure to manganese through the breathing of manganese fumes or dusts. Continued exposure can damage the lungs, liver, and kidneys. Exposure to manganese dust or fumes can also lead to a neurological condition called manganism.
