Abstract

The present invention relates to an alternative process for the recovery of metals, such as copper and zinc, in addition to cyanide, from cyanide-bearing solutions present in gold and silver recovery mining processes in a more efficient way than at present. The process includes different membrane separation processes and the use of metal sulphide precipitation reactions, which is capable of generating marketable high-concentration metal sulphide products and of recovering cyanide in a concentrated solution more efficiently than current alternatives.
