Jul 18, 2013· Interpretation and implications of pulp potentials in the flotation of sulfide minerals are presented. Mechanisms of sulfide flotation are reviewed in terms of the mixed potential model for both self-induced and collector-induced flotation. The effects of galvanic interactions among different minerals and grinding media on flotation are summarized.

There is a huge difference between the solution potential, Eh, which is dominated by the oxygen reduction reaction, and the pulp potential, Ep, which is indicative of the readiness of the sulphide minerals for flotation. Eh is easily measured using platinum sensing electrode. Ep can be measured using a gold sensing electrode or a mineral electrode.

In mineral flotation, rheological problems have limited the efficient upgrading of low-grade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.

In this research, selective flotation of Mo from the Sungun Cu-Mo concentrate was evaluated in different operating conditions. It was found that the addition of 16 kg/t Na2S into flotation pulp and aeration decreased rapidly the initial oxidized- reduction potential (ORP) of the pulp from +228mV to -597 mV (with reference to standard Ag/AgCl electrode) and increasing the amount of Na2S by 50kg ...

Apr 25, 2014· Froth flotation is a widely used process of particle separation exploiting differences in surface properties. It is important to point out that overall flotation performance (grade and recovery) is a consequence of the quality and quantity of the solid particles collected from the pulp phase, transported into the froth phase, and surviving as bubble-particle aggregates into the overflow.

The pulp redox potential, which is correlated to pulp pH and dissolved oxygen by the relation: (1) Eh = 1.23 + 0.015 log P O 2-0.059 pH also plays a role in the oxidative reactions at the surface of minerals and the complexation with collectors.

This study explores the flotation behavior of chalcopyrite in the presence of different concentrations of sodium sulfide (Na2S·9H2O) at pH 12 under controlled potential conditions. It was observed that the flotation of chalcopyrite is not depressed completely when the pulp potential is low, even at high concentrations of sodium sulfide, i.e., 10−1–10−2 mol/L.

Feb 23, 2020· A smart selection of grinding media not only effectively reduces the grinding cost but also optimizes the flotation response of valuable sulfide minerals. This review highlights the influences of grinding media on pulp chemical properties (dissolved oxygen, pulp potential, pH, and ion concentration), particle size distribution, surface morphology and species, and crystal structure of …

Pulp density describes the mass of mineral in unit volume of liquid available, usually expressed as a % (w/v). This term has most meaning in experimental systems where relatively small amounts of crushed or ground ore are suspended with continuous agitation in a large volume of liquid medium, as in laboratory scale tests of direct leaching by ...
