; accepted 28 June 2016 Abstract: This work focuses on the organic depressant, disodium bis(carboxymethyl) trithiocarbonate (DBT), as a selective depressant in copper-molybdenum sulfide flotation... be considered as a cleaner option in commercial Cu-Mo flotation separation circuits. Key words: copper-molybdenum sulfide ore; disodium bis(carboxymethyl) trithiocarbonate; depressant; flotation separation......
flotation reagent, polyaspartic acid (PAPA), was tested as a potential selective depressant in the flotation separation of chalcopyrite and Cu-activated sphalerite. The depression mechanism of PAPA...; flotation separation; depressant; polyaspartic acid 1 Introduction Chalcopyrite (CuFeS2) and sphalerite (ZnS) are the main copper and zinc minerals found in complex sulfide ores, and they are closely......
