    Four Major Flotation Separation Processes to Separate ...

     · Chalcopyrite is a widely distributed copperiron sulfide mineral, often containing trace amounts of gold, silver and other minerals, and is the main coppercontaining mineral. With the deepening of mining, low grade polymetallic refractory chalcopyrite has become an important source of copper ore. Now, let's know the common chalcopyrite flotation processes together.

  • APPENDIX

    APPENDIX

    Chalcopyrite is made up of copper ( amu), iron ( amu) and sulphur ( amu), therefore the atomic mass of chalcopyrite (CuFeS 2) is: CuFeS 2 = Cu + Fe + 2S CuFeS 2 = + + (2 x ) amu CuFeS 2 = amu Thus, stoichiometric chalcopyrite contains percent copper, percent iron and percent sulphur. Hence, the conversion factor (f Ch) to convert the ...

    The majority of chalcopyrite remains in the sulfur flotation tailings and can be readily recovered by flotation with different flotation reagents. When amyl xanthate is used, 85% of chalcopyrite can be recovered with a copper grade of % in a singlestage froth flotation. The chalcopyrite flotation concentrate can be sent back to chloride leaching circuits.

    In flotation, the size of mineral particles is one of the most important parameters: when the size becomes fine, collision efficiency of the particles and air bubbles becomes low, causing low flotation recovery. To improve the collision efficiency and flotation kinetics, agglomeration using the emulsified oil of finely ground chalcopyrite (D50 = mu;m) was carried out before flotation.
