Hydrometallurgical Processing of Manganese Ores: A Review

The production of manganese alloy from manganese ore is an energy intensive process and therefore, apart from manganese ore, power plays an important role in the production of ese alloy. There are basically two mangan processes for the manufacturing of the alloy using either one of high, medium or low grade ore, viz; Blast fur-nace and submerged electric arc furnace [SEAF]. When manganese ore ...
