The effect of copper sulphate addition on the recovery of chromite in the flotation of UG2 ore
, 2003 Chromite and talc are two major gangue minerals in platinum bearing UG2 ore processed from the Bushveld Complex in South Africa. During flotation, talc is effectively depressed by the addition of depressants. Chromite, on the other hand, is considered to
