Investigation On Flotation Separation Of Chalcopyrite From

(1) Chalcopyrite (CuFeS2) Chalcopyrite (including Cu 34.57%) is the most common copper mineral in China's copper mines, has good buoyancy. Chalcopyrite is not easily oxidized, and it can maintain natural floatability for a long time in neutral and weakly alkaline pulps. However, in a strongly alkaline (pH>10) slurry, since the surface is eroded by OH-, a hydrophilic iron …

On the other hand, chalcopyrite is cathodically polarized upon contact with pyrrhotite. The lower floatability of the chalcopyrite might be attributable to the formation of iron hydroxide from cathodic decomposition. Pulp potentials in the flotation separation decreased when either iron powder or mild steel filings was used.
