Copper Flotation Leaching

RECOVERY OF COPPER FROM OXIDE COPPER ORE BY

Most important copper beneficiation techniques are froth flotation, gravity separation, and acid leaching processes. Usually sulphide copper ores are processed by froth flotation whereas oxide copper ores are treated with acid leaching processes globally.

Copper LPF Leach Precipitation and Flotation Process

May 16, 2016Copper is got into solution by standard leaching methods. The residue is reground, given froth flotation to recover the sulphide copper, and then refloated for its pyrite. This pyrite is calcined, producing SO2, which after reaction to H2SO4 is used for leaching. The ash is reduced with coal to yield finely divided iron.

Leaching behaviour and mechanical properties of copper

Different mixtures with the copper flotation waste portion ranging from 2.5 to 12.5% by weight of the mixture were tested for copper leachability. The results show that as cement replacement materials especially clinoptilolite had clear effects on the mechanical properties.

Leaching characteristics of copper flotation waste before

Copper flotation waste from copper production using a pyrometallurgical process contains toxic metals such as Cu, Zn, Co and Pb. Because of the presence of trace amounts of these highly toxic metals, copper flotation waste contributes to environmental pollution. In this study, the leaching character

Dec 01, 2006Leaching of Cu, Zn and Pb metal ions decreased as the level of SiO 2 increased. While Cu release from vitrified copper flotation waste was 5.2 mg/L, Cu release from vitrified copper flotation waste with addition of 20% and 60% SiO 2 was 1.3 and 0.3 mg/L, respectively. Similar results were determined for Zn and Pb release.
