The Effect of Ca²⁺, Mg²⁺, SO₄^2- and PO₄^3- on Phosphate Ore Flotation

Abstract:

In the process of recycling phosphate ore processing wastewater, the accumulation of inorganic ions and the flotation reagents have a great influence on the flotation performance when they reach to a certain concentration. This paper studied the effect of Ca²⁺, Mg²⁺, SO₄^2- and PO₄^3- on the reverse flotation of phosphate ore through the single factor experiment. The experimental results show that Ca²⁺, Mg²⁺ and PO₄^3- have less effect on the flotation performance, and that a certain amount of PO₄^3- in the ore pulp can reduce the dosage of acid and improve the flotation result. SO₄^2- has a significant effect on the reverse flotation of phosphate ore and the concentration of SO₄^2- should be controlled under 1 g/L in the backwater utilization.
