Recovery of Silver, Gold, and Lead From a Complex

caustic cyanide, gold and silver extrac­ tion is usually low with complex sulfide gold-silver ores. A procedure to extract silver from sulfide ores with FeC13 was patented by Hey in 1922 (6). Considera­ ble work was completed by-Wong (7) to re­ cover lead from a galena concentrate with a combined FeC13-NaCl leach solution.

Rcovery of gold in pyritic ores - Mine Engineer.Com

2013-1-13  Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery. The fine coating of a iron compound definitely appears to be a key component of the inability of cyanide to efficiently leach low grade pyritic ores. Perhaps there is some room here for a pretreatment, to ...
