Recovery and separation of phosphorus as dicalcium
a low-grade (2.0 wt% P) iron-rich (19.7 wt% Fe) phosphate ore. The process combines leaching using dilute sulfuric acid (0.29 M) and selective precipitation using calcium oxide. During selective precipitation, ethylenediaminetetraacetic acid (EDTA) is used as a stabilizing agent to prevent iron and phosphorus co-precipitation.

This paper studied the effect of Ca 2+, Mg 2+, SO 42- and PO 43- on the reverse flotation of phosphate ore through the single factor experiment. The experimental results show that Ca 2+, Mg 2+ and PO 43- have less effect on the flotation performance, and that a certain amount of PO 43- in the ore pulp can reduce the dosage of acid and improve ...
