Oxide Copper Ore Flotation

May 04, 2021 Effect of ZnO SDS nanoparticle concentration on oxide ore flotation recovery. The effect of modified ZnO SDS nanoparticle concentration on the recovery of copper ore flotation was investigated. For this purpose, experiments were performed with different volumes of SDS modified ZnO nanoparticles (2.25, 4.5, and 7. 5 ml)

Feb 26, 2017 Oxide Copper Flotation. Flotation of oxide copper ores finds its most wide use in the Congo and Rhodesia sections of Africa. Malachite is the copper mineral recovered by Flotation in these areas. Flotation of these ores presents both mechanical and metallurgical problems which, by careful analysis by the metallurgists in charge, have been overcome

The traditional method applied for the flotation of copper oxide or mixed ores is sulphidisation, which was first developed with industrial success on Pb–Zn oxide ores in Australia (Crozier, 1991). The method involves multistage addition of sodium sulphide (Na 2 S), sodium hydrogen sulphide (NaHS), or ammonium sulphide (NH 4) 2

Flotation is suitable for copper-oxide ores with relatively complex ore properties and composition. Flotation methods for copper-oxide minerals tend to be divided into direct flotation and sulfidization flotation , , . In direct flotation, minerals are floated by direct addition of collectors and frothing reagents without activating agents or

Jul 25, 2013 The various copper occurrences in an ore are referred to in the industry as “Acid Soluble”, “Oxide Copper” or “Non-sulfide” copper on the basis of chemical analysis, thereby leaving no room for the possibility that much of this “Acid soluble” copper may not be present as well defined oxide minerals and that they may not even be amenable for flotation either with oxide collectors or with sulfidization-xanthate flotation
