For instance, lime is a depressant for pyrite (FeS2) in the flotation separation of copper sulfides. Lime would normally be added to the grinding circuit of a copper concentrator some time before flotation is carried out, for oxidation of the pyrite and the pH regulating effect to take hold. ... Flotation of Gold and GoldBearing Ores.
Copper must be assisting gold flotation as deciphered from the superior floatability of auricupride [Cu 3 Au] and tetraauricupride [AuCu] relative to native gold. At the Kemess flotation plant depending on the ore type (milled in separate campaigns), the role of some surface modifiers changes.
