gold cyanidation procedures

2016/8/8The dispersal of free cyanide in gold leach operations predicts its catastrophic effect. 18 A case was presented in Ecuador where SSGM using mercury amalgamation and cyanidation yielded 9–10 tons of gold/annum, resulting in annual releases of around 0.65 19 Otherwise, the dissolution process would be prolonged unduly due toCoarse gold is usually removed ahead of cyanidation by gold traps, blankets or other standard methods and is treated separately. Otherwise, the dissolution process would be prolonged unduly due to the concentration of coarse gold in the grinding circuit, and the danger of high gold cyanidation residues would always be present.

Effects of Potassium Nitrate (Sa ltpetre) On Gold Cyanidation* showed that saltpetre could be used as an oxidant for gold cyanidation. After using saltpetre as an oxidant in cyanide leaching, Au recovery of approximately 99% was realised whiles approximately 98% recovery was obtained from cyanide leaching involving hydrogen peroxide and atmospheric air as oxidants.
