2018-1-1 Except for the simultaneous leaching of manganese and silver from manganese–silver ores reported by Jiang et al., 2003, Jiang et al., 2004, in which sulfuric acid and hydrogen peroxide were used as additives, most reports treat the recovery of manganese and silver from their ore as two isolated processes without establishing relationships ...

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 produced in situ in the reduction stage.

2016-9-7 The mere presence of manganese in the ore is not invariably accompanied by refractoriness of the silver because the writer has known of an instance where ores of apparently similar composition and character and coming from adjacent mines behaved quite differently, one yielding only 50% of its silver

solution and manganese-silver minerals and solid solutions are leached by NaCN solutions with great difficulty. Although several laboratory tests have been successfully conducted on leaching of manganese with S02 solutions followed by leaching of silver with cyanide solutions (4, 10-11), the present study

A combined novel process was developed to extract valuable metals from manganese–silver ore. The preferential dissolution of manganese from the primary materials was achieved through reductive leaching in dilute sulfuric acid medium with sodium sulfite as the reductant.

Kinetics of silver leaching from a manganese-silver associated ore in sulfuric acid solution in the presence of H2O2 has been investigated in this article. It is found that sulfuric acid and hydrogen peroxide have significant effects on the leaching rate of silver. The reaction orders of H2SO4 and H2O2 were determined as 0.80 and 0.68, respectively.
