The Importance of pH in Flotation
To have a positive control over flotation, it is necessary to be able to determine which and to what degree it is. A cheap way to take this measurement, LITMUS stone or a pH METER is used. This is a very important measurement for the flotation operator. Some minerals like Iron pyrite will not float well in an alkaline flotation circuit.
Effect of pH on Copper Flotation Recovery VS Mass Pull
An example of testing the effect of pH on rougher flotation on pit samples and the results are presented. Since this is only an example, it needs reminding that not all ores will respond the same. Here, rougher flotation is most Selective at a pH of 9.5 as pH levels in the 9 to 10 range yielded 1% to 2% better recoveries. Mineralogy data also supports this and shows between 3% and 10% of the ...
Effect of Collector and pH on Pyrite Fe Selectivity ...
Even at optimum pH 6, over dosage of collector will negate flotation selectivity and recover copper as well as iron/lead/zinc. Also note how “letting go” of pH from 6 to 7 may have the similar effect on recovery as adding more collector and will less selectively recover more copper as well as iron/lead/zinc.
pH Ranges for Sequential Cu Pb Zn Flotation | Separation
By modifying Flotation pH to create kinetic/speed differences between the metals and achieve sequential flotation and take full advantage of the hydrophobic nature of each mineral, it is best to first lower the pH and see about recovering copper.

Effects of Soluble Metals Flotation
Most of the soluble minerals were present as sulphates. The next step was to determine the effect, on flotation, of the various sulphates. Sodium and potassium sulphates, when added to fresh tests in the proportion indicated in the analysis, yielded a 13 oz. tailing and a 650 oz. concentrate; thus producing a marked increase in the grade of concentrate without detrimental effect on the tailing.

Effects of Eh and pH on the oleate flotation of iron oxides
Many published articles relating to the effect of pH on oleate flotation of iron oxides. • Very few examine the effects of Eh as well as pH. • Low pH and low Eh are detrimental to the oleate flotation of iron oxides. • Iron oxide flotation corresponds to region of ferric oleate stability.
