Copper Sulfate In Gold Flotation

Effect of Copper Sulfate on Zinc Sphalerite Flotation

As an example of the beneficial effect of copper sulfate in the activation of zinc sphalerite toward flotation, the series of results shown in Fig. 1 is of interest. These represent rougher tests on a sample of heavy pyritic ore. The particular sample in question contained about 5.6% zinc as marmatite; and was treated in a circuit made alkaline with lime, using pine oil as a frother and ...
