• Cobalt Flotation Recovery

    The major cobalt source in the ore is the mineral siegenite. Separation and concentration of siegenite by froth flotation is complicated by the mineralogy of the ore. The siegenite is often present as an intimate replacement intergrowth with chalcopyrite (fig. 1), sphalerite, galena (fig. 2), and the iron sulfides, pyrite and marcasite. Current ...

  • Sulfide Ores - an overview ScienceDirect Topics

    Common minerals that accompany pentlandite are pyrrhotite, Fe 8 S 9, and chalcopyrite, CuFeS 2. Cobalt and platinum-group elements are also present, either dissolved in the pentlandite or present as distinct minerals. Sulphide ores that are mined for nickel and cobalt typically contain 1.5%–3% Ni and 0.05%–0.1% Co.

    Sulfide minerals are floated using mostly xanthates, dithiophosphates, and other thio compounds as collectors. The mineral-collector interactions and the selectivity in separating individual sulfide minerals from each other and from the rest of the nonsulfide particles can be controlled by a careful adjustment of pH and oxidizing, reducing, and complexing additives.
