Flotation separation of copper sulphides from arsenicNov 01, 2014· Smith et al. (2012) reported some case studies by using pulp potential control to separate copper and arsenic. In one case, tennantite was floated from the other nontennantite copper minerals (bornite and chalcopyrite) between −200 and −130 mV (SHE). Arsenic recovery in this region was between 80% and 90% while the recovery of nontennantite copper minerals was about 30%.Cited by 25Copper Lead Concentrate SeparationOct 01, 2015· The separation of copperbearing from zinc sulphides is effected by twostage selective flotation, the zinc minerals being depressed and the copper minerals brought up in the first stage with reagents similar to those required in the lead flotation section of a leadzinc plant; the zinc sulphides are floated in the second stage in the ordinary way.

Enhancing the flotation recovery of copper minerals in

Jan 01, · Flotation is a physical and chemical separation process that utilizes the difference in surface properties of the valuable minerals and the unwanted gangue minerals (Wills, 2006). Recovery of materials during flotation can be explained by the following three mechanisms (i) selective attachment to air bubbles (true flotation); (ii) entrainment in water passing through froth; and (iii) physical entrapment between
