SYSTEM AND METHOD FOR ABOVE-ATMOSPHERIC LEACHING OF METAL SULFIDES |
摘要 |
A system and method for improving leach kinetics and recovery during above-atmospheric leaching of a metal sulfide is disclosed. In some embodiments, the method may comprise the steps of: (a) producing a metal sulfide concentrate [34] via flotation; (b) moving the produced metal sulfide concentrate [34] to at least one chamber [22a] of at least one reactor such as an autoclave [20]; (c) leaching the produced metal sulfide concentrate in said at least one chamber [22a] in the presence of oxygen [82] at a pressure and/or temperature above ambient, and in the presence of partially-used [25] and/or or new [92] grinding media within the at least one chamber [22a]. Systems [10] and apparatus [20, 200] for practicing the aforementioned method are also disclosed. |
