Recovery of Silver, Gold, and Lead From a Complex Sulfide

cover gold, silver, and byproduct lead from a complex lead-zinc sulfide ore. A ferric chloride (FeCI3 ) preleach, at 40° C in 6 h, extracted about 50 pct of the zinc and formed insoluble silver and lead chlorides. Subsequent acid thiourea leaching, for 1 to 3 h at 40° C, extracted about 85 pct of the gold and silver. Lead chloride was solubilized from

sulphate), so that it is possible to achieve a high extent of leaching of the gold and silver. After bioleaching of the ore and chloride leaching of the lead sulphate, the thiosulphate leaching of gold and silver from the remaining residue was carried out (with the addition of catalyst, activator and lixiviant). The thiosulphate leaching of gold and silver takes place according to the following reactions: 4Au0 + 8S 2

Extraction Of Silver Mineral Processing & Metallurgy

Ore containing a great deal of lead— especially if the roasting was so conducted that a large part of it remained as sulphate of lead, which is not soluble in the leaching water—will give in the beginning of the leaching with the solvent a precipitate of silver with some lead ; afterwards, however, the silver diminishes, so that the precipitate of lead finally appears free of silver

Cyanidation of gold ores containing copper, silver, lead

Diagnostic leaching has been also proved to be very useful as an analytical tool for establishing the distribution of gold within different mineral phases of an ore (Celep et al., 2009). It was reported that pre-leaching successfully overcame the effect of pyrite and pyrrhotite on cyanide consumption and the gold leaching kinetics, but it had no beneficial effect when chalcopyrite was present
