    ration of copper and zinc minerals from pyrite 2. However, with selective reagents in copper flotation, amount of sphaler-ite and fine-ground pyrite grows in the zinc flotation cycle, which mutilates flotation process. It is known that zinc cycle of copperzinc ore flotation uses xanthate modifications that are not selective relative to pyrite.

    The Adsorption Of Cu Species Onto Pyrite Surface And Its

    The adsorption of Cu species onto pyrite surface and its effect on flotation were investigated by using microflotation tests, first-principle calculations, and XPS surface analysis. The results indicated that the flotation of pyrite appears to be activated with CuSO sub 4 sub only at alkaline pH, while being depressed at acidic and neutral pH. The adsorption of copper ions on pyrite surface ...

    The Depression Of Pyrite In Selective Flotation By

    Pyrite is a gangue mineral widely associated with valuable minerals. It is problematic to deal with in differential flotation because it easily reports to flotation concentrates. Pyrite may float due to natural or self-induced hydrophobicity or collector-induced hydrophobicity. Its flotation can also be enhanced by the activation of copper or ...
