Introduction. Southern Africa is endowed with a large variety of minerals concentrated in commercially exploitable ore deposits. The historically low cost of electrical energy and labour, and the vision of pioneers such as the late Dr H.J. van der Bijl (Basson, Curr, and Gericke, 2007; SAAE, undated), led to the development of a strong pyrometallurgical industry.
[سؤال0183;Mineralogical investigations have also revealed that Manganese occurs in the minerals as higher oxides, mainly pyrolusite (MnO 2).Since MnO 2 is stable in direct acid or alkali dissolution, the possible reduction of the insoluble tetravalent manganese(IV) to soluble bivalent manganese(II) is necessary to recover manganese from its ores. The reduction of manganese[سؤال
