Manganese metallurgy review. Part I: Leaching of ores

2016-1-5  Metallurgical grade manganese ores (N40% Mn) areusually processed into suitable metallic alloy forms bypyrometallurgical processes, which are very similar to ironpyrometallurgical processes. Ferro-manganese is a com-monly used alloy. In its production process, a mixture ofmanganese ore, reductant (a form of carbon) and flux(CaO) are smelted at above 1200 °C to enable reductionreactions and alloy formation. Standard grade ferroman-ganese contains more than 76% Mn and about 7% C, andcan be produced either in a blast furnace or in an electricfurnace (Yucel and Ari, 2001). High carbon ferro-manganese can be made by three different practices:blast furnace, discard slag electric furnace, and highmanganese slag electric furnace. Medium carbon ferro-manganese can be produced by a de-carbonation processor through a redox reaction between silicon in thesilicomanganese alloy and manganese
