The impact of water quality on flotation performance pH Eh DO and dissolved species in recycle water streams eg thickener overflow decant tailings dam return contributing to a circuit water are also shown in Table I TDS and TOC levels may also be raised by reagent addition for pH control eg lime and recycled organics eg

A detailed study was conducted to evaluate the effect of particle size pH flotation time collector type and addition on efficiency of tennantite flotation It was shown that maximum copper recovery of 953 was obtained at pH 123 by was suggested to grind up to 6572 of 0074 mm to achieve the optimum recovery of copper and high

Effect of Eh and pH on the flotation of enargite using seawater Highlights•Enargite flotation in seawater is depressed at reducing and oxidizing conditions•Calcium and magnesium interact with enargite not only by physical means but also through chemical interactions at high Eh•The depressing effect of calcium is stronger than the depressing effect of magnesium on enargite flotation at

Another important parameter whic h has a remarkable effect on the flotation of sulphide minerals is pH It is It is established that xanthates decompose in acidic environment and hence resulting

ABSTRACT Flotation was proved to be effective for decarburization and removal of dioxins from hospital solid waste HSW incinerator fly ash but weathering makes it difficult The effects of three types of surfactants including nonionic Tween 80 anionic SDS and cationic CTAB at different pulp pH values on the flotation performance of weathered HSW incinerator fly ash were investigated

The pH was monitored as the flotation pH 3 The watermineral mixture was then transferred into the microflotation cell and floated with N 2 at an average flow rate of 25 cm 3 for 20 seconds The final pH was measured to ensure that no appreciable change had occurred during flotation 64 Results and Discussion 64a Effect of pH on the
