    Effect of Copper Sulfate on Zinc Sphalerite Flotation

    Copper sulfate, when used as an activator in flotation of sphalerite, forms an invisible but physically detectable film of cupric sulfide on the surface of the sphalerite particles, as evidenced by increased electric conductivity, by chemical metathesis, and by the ability to deactivate with solutions of alkali cyanides, which are known as solvents of copper sulfides.
