ore flotation complex

The optimum potential range of the chalcopyrite electrode was +50 to +150 mV (vs. SHE) in the copper flotation of the complex sulphide ore types studied. The optimum potential of the sphalerite composite electrode in the zinc flotation of the three ore types was that obtained using full aeration.

May 12, 2020 Abstract. Froth flotation is the most effective industrial method used to separate fine-grained minerals. The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation. In this review, studies on the interactive effect among minerals on the flotation of iron ores, magnesite ores, and scheelite ores …

Investigations into the Recovery of Platinum Group

In the flotation of platinum group minerals (PGMs) it has generally been assumed that they will behave similarly to base metal sulfides and thus sulfide reagent regimes are generally used in such flotation plants. However the tellurides and arsenides of platinum and palladium contribute about 50% of the PGMs present in the Platreef ore, located in the northern limb of the Bushveld Complex of ...
