Two-stage leaching of manganese and silver from manganese–silver ores ...
Abstract The development of a hydrometallurgical process to recover manganese and silver from manganese–silver ores is reported. Insoluble manganese(IV) was reduced to soluble manganese(II) in an aqueous medium with calcium sulfide (CaS) as the reductant, and the resultant residue was then leached by a sulfuric acid solution. Thiosulfate (S2O32 −) was
