Coarse chalcopyrite recovery in a universal froth flotation machine
An interpretation of the observed behaviour is that the chalcopyrite in the ore is softer than the quartz in which the mineral is embedded. Thus the ore will break preferentially along grain boundaries involving the soft ore. For large particles, the concentration of soft particles is low, and the grains behave like pure quartz. ...
