Gold and Base Metal Recovery from a Massive Sulfide Ore.
Ch 17 in Advances in Gold and Silver Processing SME/AIME 1990 :161-178
A procedure was developed by the U.S. Bureau of Mines for recovering gold, silver, cobalt, copper, and zinc from a massive sulfide ore by a hydrometallurgical process. The procedure consists of (1) oxygen pressure leaching, (2) iron, arsenic, and copper removal from the leach solution by precipitation, (3) selective extraction of cobalt and zinc from solution, (4) electrodeposition of the cobalt and zinc from the strip liquor, and (5) cyanidation of the pressure leach residue to recover gold and silver. The results are discussed in terms of efficiency of metal recovery, and conclusions are drawn as to possible benefits and broad applications of the process.
