Abstract
A copper/molybdenum separation system uses sea water in the roughing circuit and desalinated water in cleaning circuit. In both roughing circuit and cleaning circuit, hydrophobic engineered media are used to recover the mineral particles of interest. The cleaning circuit includes a molybdenum loading stage configured to contact the conditioned pulp with the engineered media in an agitated reaction chamber, and load the hydrophobic molybdenite on the engineered media.
Claims23
A copper/molybdenum processing system comprising
- a roughing circuit and
- a cleaning circuit, wherein the roughing circuit comprises a sulfide separation stage arranged to receive a slurry comprising a ground ore product and sea water, the ground ore product comprising copper sulfide minerals and molybdenum sulfide minerals, wherein the cleaning circuit comprises a copper/molybdenum separation stage arranged to receive bulk sulfide concentrate mixed with desalinated water, the bulk sulfide concentrate comprising the copper sulfide minerals and the molybdenum sulfide minerals recovered in the roughing circuit.
