The effect of surface potential on the flotation of chromite

Abstract The flotation of chromite from “slime fraction” of the gravity circuit of Kemi concentrator, Finland was studied. The main gangue minerals are chlorite, tremolite and talc. Amines or fatty acid collectors are normally used for this sort of mineral composition. Theoretically, a sufficient selectivity should be expected in the region where the surface charge of chromite is opposite ...
