molybdenum flotation operations due to its natural flotation behavior (Kelebek, 1988; Cumming et al., 2000; Tingshu et al., 2011). Smit and Bhasin (1985) observed that if a twocomponent blend of a higher molecular weight of petroleum hydrocarbon and lower molecular weight diluent oil were used, the better results could be obtained rather than using single component of higher molecular weight ...

Abstract 2,3disulfanylbutanedioic acid (DMSA) was found to be a selective depressant in the flotation separation of copper– molybdenum sulfides. 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 ...
