分金(银)渣氰化工艺的改进

Improvement of the cyanide leaching process of the residue of gold(silver) containing

根据对分金 (银 )渣中金、银物相组成的分析结果 ,对分金 (银 )渣氰化工艺进行了相应的改进 ,消除了铅对金氰化浸出的不利影响 ,并延长了银的浸出时间 ,从而显著提高了金、银的浸出率。

After the treatment of copper anode slime,the gold(silver)contained in the residue must be separated through analyzing the gold and silver content of the residue,the cyanide leaching process of the residue was improved, and the adverse influence of the lead on the leaching of gold was eliminated, the leaching time of the silver was also prolonged, so the cyanide leaching rates of gold and silver were increased markedly.
