Flotation separation of copper sulphides from arsenic

Nov 01, 2014· Other researchers such as Fornasiero et al. (2000) and Byrne et al. (1995) also used pre-oxidation to separate copper sulphide minerals from arsenic minerals, but they found that arsenic minerals were more oxidised resulting in depression in the flotation of copper sulphide minerals.

flotation in order to separate and concentrates copper sulfide minerals from gangue minerals. Leaching time was in a range of 20 to 240 min, while the initial H2SO4 concentration in the leaching solution varied from 0.05 M to 0.3 M. The particle size was 90% –74 μm; stirring velocity 300 rpm, while the phase ratio was S:L = 1:2.

The process involves a series of flotation known as the differential flotation. In the flotation of copper-zinc massive sulfide ores, flotation properties of copper and zinc are determined by the nature and composition of the ore. Copper zinc massive sulfide is even regarded as the most complex ore and consequently the most difficult to treat.

Srdjan M. Bulatovic, in Handbook of Flotation Reagents, 2007 Processing characteristics of a massive sulfide ore. When using a conventional flotation reagent scheme and flowsheet, only a few of these ores respond (i.e. lime + NaCN + collector), giving extremely poor metallurgical results. The majority of these ores require a specific treatment process to achieve satisfactory metallurgical results.
