    Abstract:

    Copper ore deposit Veliki Krivelj belongs to porphyry copper ore with low copper grade. The main copper mineral is chalcopyrite and minor chalcocite, but the principal sulphide mineral is pyrite. Testing ore samples had low copper contents about 0.25% Cu. The classical flotation scheme by collector xanthates does not offer satisfy results on copper recovery and concentrate grade. An extensive investigation on laboratory conditions with collectors type tiono carbamates led to good results on flotation recovery and concentrate grade as well as a little bit in energy saving in grinding process. The obtained results will be presented in the paper in shorter form.
