Improved gold and silver extraction from a refractory 2011/1/1& 0183;& 32;Cyanide leaching of the ore consistently resulted in low extraction of gold 49% and silver 18% confirming the refractory nature of the ore. Alkaline sulphide treatment of the ore under suitable conditions was shown to leach out up to 85% Sb, which remarkably improved the extraction of silver from < 18% up to 90% Ag in the subsequent cyanidation step.Cited by: 74Gold Extraction - an overview ScienceDirect TopicsThe effect of pH value on gold extraction for various ore types is shown in Figure 28.4.Greatly increasing pH value has a beneficial effect on gold extraction for both oxide and sulfide ores and stabilizes ∼pH 9.5–10.0, whereas for some carbonaceous ores, pH value the recovery of gold from sulphide oresSulphide Gold Ore Treatment by Leaching and Flotation Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return.
