Extraction of gold using cyanide NZQA
2015-8-24 Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble. To make gold soluble sodium cyanide (NaCN) is

The Chemistry of the Extraction of Gold SAIMM
2011-5-29 THE CHEMISTRY OF THE EXTRACTION OF GOLD Cu(CN);- and Cu(CN)!-. The insoluble gold cyanide compound AuCN precipitates from acidic solutions of aurocyanide ions as follows: Au(CN); + H+ = AuCN + HCN. (15.2) This reaction takes place readily in strongly acidic solution and slowly in weak acid solutions (pH 2 to 3).
