Flotation concentrates can also be processed using hydrometallurgy in which the metal sulfide is dissolved (leached) into an aqueous solution (Bergy and Yianatos, 2001). Most oxide of copper minerals dissolves readily in sulfuric acid so that leaching is reasonably straight forward. A concentrated, pure copper sulfate solution suitable for

For copper, the Pourbaix diagram reported by Chander (1988)for the Cu–S–DTP − –H 2 O system shows that the best operating conditions for recovering copper found in the present work (Eh 0.27 V and pH 7.4) falls in the predominance area of CuDTP. This may serve as an example of the possible role of metalthiol compounds in the flotation behavior observed.

MEI Blog: Challenges in copper flotation - Barry A. Wills

Sep 10, 2011 · Until 1907 practically all the copper mined in the USA was from underground vein deposits, averaging 2.5% Cu, whereas flotation allowed the mining of porphyry deposits of only 0.6% grade. Nevertheless, the flotation of copper ores still presents challenges to the minerals engineer.

pyrite depression in the copper flotation - ewags

Flotation tests and Cryo XPS analyses in this study indicate that pyrite may be depressed in copper flotation with the addition of lime despite copper activation occurring on pyrite surface. The hydrophilic calcium and iron oxidation species may form on pyrite surface and be responsible for pyrite depression.
