[PDF] Selective depression effect in flotation separation ...

Abstract 2,3-disulfanylbutanedioic 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 ...
