sulphide gold ore processing

Biogenic sulphide for cyanide recycle and copper

Coppergold ore processing (higher copper values than gold values) generally involves flotation and smelting. In the latter case, gold credits are obtained from the smelting of the copper concentrate, and if gold reports to the flotation tailings, they may also require cyanidation. Biogenic sulphide for cyanide recycle and copper recovery

Sulphide Gold Recovery. Pre-concentration of coarse 350 500 micron sulphide-associated gold ore, using the InLine Pressure Jig, is required to reject gangue from the high value material. The IPJ, a classic pre-concentration device, is effective in gangue rejection prior to further processing of valuable gold-bearing material....
