The flotation of chalcopyrite and sphalerite from copper and copper-zinc ores has been achieved without using,
Approximately 76% of the copper was recovered with a concentrate grade of 22.5% within the first minute of the collectorless flotation. At the end of the 10 min flotation, 90% copper recovery and 10.8% concentrate grade were achieved.INFLUENCE OF FROTHER TYPE AND DOSE ON COLLECTORLESS,,Influence of frother type and dose on collectorless flotation of copper-bearing shale 549 minutes and after this time only the aqueous solution of,The collectorless flotation of sphalerite,The flotation of sphalerite has been demonstrated without the use of collectors. The effect of redox potential, pH, and copper-activation have been investigated in tests using samples of pure mineral.

10.05.2005· As mentioned above, although there is some dispute, it is generally thought that collectorless flotation of certain sulphide minerals require an oxidising environment. All flotation machines can be arranged to provide an oxidising environment required by the reaction to render the sulphide mineral particles hydrophobic.Collectorless Flotation of Sulphide Minerals:,Collectorless flotation is reviewed from the viewpoint of classical oxidation studies through to modern electrochemical, surface chemical and spectroscopic investigations coupled with flotation studies.
