采用电积和部分酸化交替的方法处理金矿贫液产出的高浓度铜氰溶液，有效地回收了铜、锌和氰．经过４～５次电积－部分酸化循环，高浓度钢氰化物溶液中铜浓度由３０ｇ／ｌ降至４．５ｇ／１，从阴极获得了平均含铜７１％的黄铜（Ｃｕ－Ｚｎ合金）或含铜９８．６％的粗铜，平均阴极电流效率为６８％。氰则以ＮａＣＮ溶液得到回收。铜的回收率为９９．２％，氰的回收率为９０％。电积液可循环使用，无废液排放。 The electrowinning and partial acidification alternation methods were used to treat the high concentrations of copper cyanide solution produced from the gold lean solution, thus effectively recovering copper, zinc and cyanide. After 4 to 5 cycles of electrowinning-partial acidification, the copper concentration in the high-concentration steel cyanide solution dropped from 30 g / l to 4.5 g / l, and the average copper content of 71% was obtained from the cathode (Cu-Zn alloy ) Or 98.6% blister copper with an average cathode current efficiency of 68%. Cyanide is then recovered as a NaCN solution. The recovery of copper was 99.2% and the recovery of cyanide was 90%. Electrolyte can be recycled, no waste discharge.
