  • Contains more than 35% commercially exploitable manganese


Manganese (Mn) is a hard silver-white metal and an allotropic metal, meaning its crystal structure changes with temperature. Only ores containing more than 35% manganese are considered commercially exploitable. Impurities include oxides of other metals such as iron, which are reduced along with manganese during melting. non-metallic elements such as phosphorus, sulfur and arsenic; and metallic “gum oxides” such as silica, alumina, lime, and magnesia, which, with the exception of silica, generally remain in the slag after smelting. Manganese is mainly mined in South Africa, Australia, China, Gabon, Brazil, India, Kazakhstan, Ghana, Ukraine and Malaysia.
