Mechanisms of bulk flotation and segregation of copper cobalt

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

    Sep 28, 2021 Abstract The M ssbauer emission spectroscopy has been used to study the mechanisms of grain-boundary diffusion and grain-boundary segregation of 57Co in polycrystalline Nb. It is shown that Co atoms diffuse along the grain boundaries of niobium by the interstitial mechanism. The relative intensity of spectral lines as a function of temperature has been analyzed. The grain

    Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt minerals. Cobalt depression can be enhanced by small cyanide dosages. If the cobalt is found with chalcopyrite, bulk flotation can be carried out with xanthate at pH 10, and separation made at pH 4 with an amine and combinations of fatty acid to recover the cobalt minerals
