摘要：

An outline of a hydrometallurgical method employed for the processing of a copper sulphide concentrate is presented. It consists in leaching the concentrate with acid ferric sulphate solution, followed by electrolysis of the copper with simultaneous anodic regeneration of the leaching agent in electrolysers with diaphragms. Each operation, concentrate leaching, high-temperature crystallization of excess leaching agent in the form of FeSO4·H2O and diaphragm electrolysis, are discussed and described. The basic feature of the process is the double regeneration of the leaching agent which makes it possible to decrease the ferric ion concentration in recycled solutions to about 50% of the stoichiometric amount resulting from the leaching reactions. Electrolytic copper of more than 99.95% purity is obtained as a product. The method eliminates environmental pollution and solutions with high metal concentrations are circulated in a closed system. © 1979.
