WO2000015346A1 Collectorless flotation Google Patents

The present invention relates to a process for improving the recovery of valuable sulphide minerals. The process involves determining an Eh range within which the valuable sulphide mineral may be recovered by flotation without the need of a collector. The slurry is then subjected to flotation in a pneumatic cell (50) at such a speed that the slurry remains within the Eh range during flotation.

Collectorless Flotation of Sulphide Minerals: Mineral

Collectorless flotation is reviewed from the viewpoint of classical oxidation studies through to modern electrochemical, surface chemical and spectroscopic investigations coupled with flotation studies. Sulphide minerals apparently oxidize through a continuum of metal deficient sulphides of decreasing metal content through to elemental sulphur.

Collectorless flotation MIM Holdings Limited

The collectorless flotation of chalcopyrite requires that the flotation occurs in a neutral or slightly oxidising environment. Previous studies have shown that freshly fractured flotation of chalcopyrite increased when the redox potential (Eh) was in the neutral or slightly oxidising region. The flotation process also requires that the

Effects of Xanthate on Flotation Kinetics of Chalcopyrite

However, in this paper, even though two minerals have similar particle size compositions (as seen in Figure 1), the collectorless flotation process of chalcopyrite, rather than talc, is found to conform to the classical first-order kinetics model. Therefore, aside from size composition, the morphology of the particle also has a certain effect
