Molybdenum Recovery
Molybdenum is commonly recovered as a by-product from copper-molybdenum porphyry deposits.
Regrinding
Copper-molybdenum concentrate is reground to P80 = 20-38 microns to liberate molybdenite from copper sulphide minerals.
Selective Flotation
Copper minerals are depressed using sodium sulphide while molybdenite is floated. Multiple cleaning stages produce >48% Mo grade concentrate.
