extraction process of copper and cobalt before flotation

extraction process of copper and cobalt before flotation

for the extraction of copper and cobalt from sulfides-bearing ores. After obtaining a sulfide concentrate containing a sufficient grade of cobalt and copper by flotation, a thermal process (roasting) is applied to the concentrate to transform most of the cobalt and copper sulfide to a soluble sulfate, while iron

    A New Process for Cobalt Nickel Separation

    A New Process for Cobalt – Nickel Separation By D.L. Jones 1, ... For sulphide ores, there is another alternative; if the ore can be concentrated by flotation, matte smelting is used instead of leaching. This combination of flotation and smelting effectively ...

    Solvent extraction of Cu, Mo, V, and U from leach

    Aug 03, 2017 Flotation tailings from copper production are deposits of copper and other valuable metals, such as Mo, V and U. New hydrometallurgical technologies are more economical and open up new possibilities for metal recovery. This work presents results of the study on the extraction of copper by mixed extractant consisting p-toluidine dissolved in toluene. The possibility of simultaneous liquid

  • Flotation and Tailing Discarding of Copper Cobalt Sulfide

    Flotation and Tailing Discarding of Copper Cobalt Sulfide

    The mineral composition of copper–cobalt ores is more complex than that of copper sulfides, and it is also difficult to discard tailing efficiently in primary flotation for the fine-grained disseminated of ore. In this work, a mineral liberation analyzer (MLA) was employed to study the characteristics of minerals. As a significant mineralogical characteristic, the liberation degree of useful
