    flotation separation of molybdenite from chalcopyrite

    Sep 01, 2020· Flotation recovery of molybdenite or chalcopyrite as a function of pH with or without L-cysteine (4 × 10 -4 mol/L), kerosene (2 × 10 -4 mol/L) and terpineol (20 mg/L). In the flotation separation of Cu-Mo sulphide ore, a depressant usually plays an important role

    four major flotation separation processes to separate

    This process is suitable for processing chalcopyrite which is easy to separate byflotationin the ore. It can separate copper fast and early when the grinding fineness is low. The difficult part of the ore can be recovered using the strong collector along with other minerals in the case of regrinding or no more grinding
