Flotation Results. Figure 2 shows the effect of grinding fineness on recovery rate of copper. It is observed that a rise of the proportion of the grinding fineness of −0.074 mm from 60 to 80% obviously increased the copper recovery, then decreased when it exceeded 80%. This is because the initial appearance was dissociation fragmentation ...
