Abstract:

The technology of direct electrochemical processing of copper sulfide concentrates was developed, providing the following processes: electric smelting of concentrates on matte, casting the last into anodes and their temperature control; electrolysis of sulfide copper-iron anodes, obtaining high-quality copper powder; crystallization of iron sulfates and extraction of elemental sulfur from anode sludge.
The proposed technology has a number of important advantages over existing pyrometallurgical methods, such as the environmental safety. The main steps of the proposed technology were tested in semi-industrial scale.

Keywords:
