Selective depression effect in flotation separation of ...

2015-9-1  The flotation results suggest that a low dosage of DMSA has a strong depression effect on chalcopyrite in the pH range between 4 and 12. At pH 6, the recoveries of molybdenum are up to 85%, 75%, and 80% while those of chalcopyrite are 15%, 5%, and 20% respectively when flotation tests are carried out with single minerals, mixed minerals and molybdenum-bearing copper concentrates.

REACTIONS IN CUBANITE AND CHALCOPYRITE

2007-4-22  Chalcopyrite, CuFeSz, and cubanite, CuFe"Ss, are prominent phases in the central portion of the Cu-Fe-S phase system; both compounds, especially chalcopyrite, are important ores of gopper. CuFeSz is tetragonal at low temperatures (chalcopyrite) but during heating it reacts first to cubic intermediate solid solution (iss) and

For this reason, the separation of molybdenite from chalcopyrite has always been a challenging task, and efforts are now being carried out to synthesize selective reagents that can depress chalcopyrite efficiently during flotation of molybdenite . In most cases, where the molybdenite is only an economical mineral, depressants are usually required to depress the floatability of chalcopyrite

Lime use and functionality in sulphide mineral

2019-11-1  Richardson and Walker (1985) showed that the flotation of chalcocite, bornite, chalcopyrite and pyrite with potassium ethyl xanthate is controlled by the conditioning redox potential (Eh). The active surface entities were found to be metal xanthates for chalcocite and bornite, dixanthogen for pyrite, metal xanthate for initial flotation of chalcopyrite and dixanthogen for full flotation.
