Assessment of water quality effects on flotation of

2014-10-15  For each flotation test, one kg of the crushed ore has been subjected to wet grinding in ball mill for obtaining granulometry of d 80 of 74 μm and flotation pulp with specific gravity of 1200 g/L. The ore has been initially subjected to talc pre-flotation during 3 min followed by copper–cobalt bulk rougher for 30 min.The talc pre-flotation has been carried out with 200 g/t sodium silicate ...

Assessment of water quality effects on flotation of

Thiosulphate presence depending on concentration promotes or hinders cobalt and copper flotation. Abstract Results from lab scale flotation show that when process water was re-used copper and cobalt recovery from an oxidized ore decreased respectively with 25% and 30% at the rougher stage bringing lower grade concentrate as well.

2015-4-10  Furthermore, the discharging of contaminated water of the open pit to this river could affect the river water quality. Copper, manganese and zinc were the most abundant metals in the concentrator plant water samples, respectively (Fig. 10c). Due to lime addition, it is clear that a large portion of metals is removed from the processing water to the sludge as hydroxide precipitates.
