Cyanide Leaching Chemistry Gold Cyanidation
Cyanide Leaching Chemistry Gold Cyanidation. Previous Next View Larger Image. The reactions that take place during the dissolution of gold in cyanide solutions under normal conditions have been fairly definitely established. Most agree that the overall cyanide equation for leaching and cyanidation of gold is as follows: 4 Au + 8 NaCN + O2 + 2 H20 = 4 NaAu(CN)2 + 4 NaOH. Cyanide Leaching ...

Thiosulfate leaching of gold—A review .
Thiosulfate leaching can be considered a nontoxic process, the gold dissolution rates can be faster than conventional cyanidation and, due to the decreased interference of foreign cations, high gold recoveries can be obtained from the thiosulfate leaching of complex and carbonaceoustype ores. In addition, thiosulfate can be cheaper than cyanide.
