Control of pH is one of the most widely applied methods for the modulation of mineral flotation In this study the effect of pH on potential in solution and sulphur minerals flotation is discussed with various electrodes The electrodes were platinum gold chalcopyrite pyrite and galena In solution potentials were linearly dependent on pH with a different slope for each electrode.Water quality had no effect on the collectorless flotation of chalcopyrite which was very strong in excess of 96 copper recovery but all three lower quality waters had a detrimental effect on the recovery of bornite compared to that obtained in distilled water The depressant effect was so strong that the little recovery achieved in these.

PH was varied in the moly flotation in roughers while attempting to maintain a eH in the low 500 mV The results of the test shows that the best recoveries of moly are achieved at pH values of 9 and below The copper recoveries appear to get activated at these low pH values but the copper recovery is sufficiently low (below 40 ) that an effective separation will happen.Nov 19 2013 The role of pH solid content water chemistry and ore mineralogy on the galvanic interactions between chalcopyrite and pyrite and low alloy steel balls were investigated in the grinding of Sarcheshmeh porphyry copper sulfide ore All these factors strongly affect the galvanic current between the minerals and the steel during the grinding process.
