ABSTRACT:
This invention provides a novel and an improved hydrometallurgical method for recovering copper values from copper concentrates. The method essentially comprises the following steps:
A. forming an aqueous leach solution containing chloride or bromide ions in a predetermined concentration;
B. dispersing copper concentrates in such leach solution to form a slurry;
C. carrying out the leaching operation of the slurry at an elevated temperature and under an overpressure of oxygen so as to transform a major proportion of the copper values present in the concentrates into a solid basic copper sulphate;
D. separating the resulting leach residue containing the basic copper sulphate from the leach solution; and
E. recovering the copper values from the obtained leach residue.
The process is simple and efficient and can be carried out either batchwise or continuously.
