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).
