Flotation Reagents - Mineral Processing Metallurgy

Jun 08, 2016  The function of regulators is to modify the alkalinity or acidity in flotation circuits, which is commonly measured in terms of hydrogen ion concentration, or pH. Modifying the pH of a pulp has a pronounced effect on the action of flotation reagents and is one of the important means of making otherwise difficult separations possible.

Mineral Flotation - International Mining

Nov 01, 2011  The overall flotation circuit was not performing at optimal rate due to entrainment problems in the rougher cells when feed density increased from 45% to 55% solids, typically at 105 t/h. In anticipation of future production levels and as part of Stawell’s focus on operational excellence, it was decided to upgrade the flotation circuit.

Froth Flotation of Iron Ores

Jan 02, 2012  For depressant-kaolinite interactions, it was found that selective depression of hematite against kaolinite largely depends on strict pH control in iron ore flotation circuits and the level of ionic strength in iron ore flotation pulp. The presence of calcium and magnesium is particularly detrimental to kaolinite removal from iron ore[32].
