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 ...
