separating molybdenite from chalcopyrite

Flotation separation of molybdenite from chalcopyrite

Sep 01, 2020· The flotation test results indicated that chalcopyrite and molybdenite had high recoveries of more than 90% and 80%, respectively, in the tested pH range of 4–12; thus, it would be considerably difficult to separate chalcopyrite from molybdenite

Flotation separation of molybdenite from chalcopyrite

Jun 15, 2020· To further confirm that ferrate can selectively depress chalcopyrite, thereby resulting in the separation of chalcopyrite from molybdenite, flotation tests were performed on the mineral mixtures (see Fig. 1(c)). In the presence of ferrate, the trend observed was the same as that of single-mineral flotation, but the flotation recovery of copper was slightly higher than

potential in chalcopyrite-molybdenite separation. The potentials were reported with reference to the standard Ag/AgCl electrode. The results demonstrated that the flotation of chalcopyrite was large only when the potential exceeded 100 mV [9-11]. Based on thermodynamics, it is expected that dixanthogen will form at potentials greater than 100
