the gold industry has been seeking alternative reagents for leaching gold from low-grade ores for the past 25 years. the cost and transport of cyanide, the poor recovery of gold from carbonaceous ores, the lack of selectivity of cyanide towards copper minerals and the cost of waste treatment are real factors which can make cyanide unattractive in some circumstances.

hello all, i work in a cil plant, processing oxide ore with more and more intrusion of sulphides (fresh ore body). the plant is designed for oxide ore but we noticed that at a certain blending, the transitional ore could be processed. a high consumption of cyanide and low gold extractions are related to the presence of oxide copper minerals
