Abstract
A process for at least one of (1) recovering at least one first metal other than manganese from a first ore containing reducible manganese, and (2) recovering at least one second metal from a second ore containing the second metal and at least one metal sulfide of a metal other than the second metal and manganese; the process comprising at least one of: (A) contacting the first ore with an aqueous composition and a material containing at least one metal sulfide in the presence of a metal redox couple more positive than about +0.1 versus the standard hydrogen electrode, W. M. Latimer convention, at conditions effective to (1) chemically reduce at least a portion of the manganese, (2) oxidize at least a portion of the metal and/or the sulfide from the metal sulfide, and (3) at least partially liberate the first metal from the first ore, and recovering the first metal from the first ore; and (B) contacting the second ore with an aqueous composition and at least one reducible manganese-containing material in the presence of a metal redox couple more positive than about +0.1 versus the standard hydrogen electrode, W. M. Latimer convention, at conditions effective to (1) chemically reduce at least a portion of the manganese, (2) oxidize at least a portion of the metal and/or the sulfide from the metal sulfide, and (3) at least partially liberate the second metal from the second ore, and recovering the second metal from the second ore.
