PROCESS FOR RECOVERY OF COPPER FROM ARSENIC-BEARING AND/OR ANTIMONY-BEARING COPPER SULPHIDE CONCENTRATES |
摘要 |
A process for the extraction of copper from a feed material comprising at least one of arsenic and antimony-bearing copper sulphide minerals is provided. The process includes fine-grinding the feed material and after fine-grinding, subjecting the feed material to pressure oxidation in the presence of surfactant and a halogen to produce a product slurry. The process also includes subjecting the product slurry to liquid/solid separation to obtain a pressure oxidation filtrate and solids comprising at least one of a compound of arsenic and a compound of antimony, and recovering copper from the pressure oxidation filtrate. |
