of manganese-rich rocks and sediments, manganese occurs ubiquitously at low levels in soil, water, air, and food. In the United States, most manganese ore is smelted to produce ferromanganese, which is a manganese-iron alloy (ATSDR, 1997). The latter is used primarily in the production of steel to improve stiffness, hardness, and strength.Web
