Abstract

The technological scheme of processing the off-balance copper sulphide ore was considered, including separation of the rough flotation copper concentrate followed by roasting, sulfuric acid leaching. The modes were worked out for solution processing by extraction and for producing cathode copper.

Keywords

Processing scheme, pellets, copper concentrate, roasting, leaching.
