mechanisms of phosphate depression flotation

Mg2+ and Ca2+ ions also affectflotation of phosphateores with fatty acids. In this case, thedepression mechanismis not caused by precipitating magnesium hydroxides on the mineral surface but by precipitation of collector insoluble salts, and the same ions are responsible fordepressionin both cases
