Keywords: Copper molybdenum separation, high copper low molybdenum, restrain of talc and other clay mineral, adsorption stripping agent, flocculation depressant

Technological difficulty: molybdenum entrainment in cooper concentrate, during copper molybdenum separation test, because of high copper low molybdenum and talc and other clay minerals entrainment, result in copper and molybdenum separation effect is poor, no molybdenum concentrate products.

Solution: by cooperatively using adsorption stripping agent and flocculation depressant, effectively inhibit talc, mica and other easy-floating gangue; (2) In the technology, make concentration and select discharge of a tailing, discharge the gangue minerals which are activated in the roughing process as soon as possible, to avoid the disrupting the flotation process; middlings centralized return, restrain and throw away as earlier as possible, let the gangue minerals discharged to the tailing.
