FLOTATION SEPARATION OF PENTLANDITE FROM PYRRHOTITE USING SULFUR DIOXIDE-AIR CONDITIONING A flotation process for the selective beneficiation of sulfide ore. In brief, the ore is slurried, conditioned with sulfide reagent, thickened and ground, conditioned with xanthate, floated and conditioned with lime, sulfur dioxide and air to depress pentlandite and promote chalcopyrite and pyrrhotite flotation. The chalcopyrite is promoted by use of cyanide and control of redox potential. |
