Operating Practices In The Beneficiation Of Major Porphyry

Apr 01, 1998 The presence of clay in the ore reduces the flotation rate of copper in all cases and increases copper losses in the tailings. Recent research work 10 on the high-clay Escondida ore revealed that the rate of copper flotation in the laboratory was much greater than that of the operating plant. This effect is shown in Figure 2.

The presence of shale, the source of carbonaceous matter in the ore, has also a negative effect on flotation and pyrometallurgical processes. The presence of clay minerals and organic carbon in shale makes the production of high quality flotation concentrates, without excessive loss of copper and other metals in the flotation tailing, difficult.
