    Jul 01, 2004· However, if theflotationrecoveries of gold andsulfideare unsatisfactory, reverseflotationof the carbonate minerals is a possible alternative. In this study, calcite and dolomite were used as representative carbonate minerals, and pyrite and chalcopyrite as representativesulfideminerals to study the feasibility of the reverseflotation.

    Apr 01, 2019· Abstract. Theflotation separation of molybdenite from copper sulfide minerals (mostly chalcopyrite) typically relies on the use of toxic inorganic depressants such as cyanides and sodium sulfide/hydrosulfide. In this work, a nontoxic, biodegradable and cost-effective derivative of the natural polysaccharide chitosan, O-Carboxymethyl chitosan (O-CMC), is investigated as an alternative …
