The effective separation of apatite and dolomite is always the focus of phosphate ore flotation research.The effect of citric acid (CA) on the flotation reaction of apatite and dolomite was studied. The flotation behavior of these two minerals was evaluated through micro-flotation experiment. The results of micro-flotation experiment Fig. 8 also shows that the recovery of dolomite decreases from pH 4 (40%), to 7 (16%) to 10 (8%). For monazite, the maximum floatability was achieved at pH 7. The amount of floated monazite was 6%, 32% and 10% at pH 4, 7 and 10, respectively, comparable to flotation with benzohydroxamic acid.Flotation studies of monazite and dolomite ScienceDirect

Improving flotation separation of apatite from dolomite

The results from flotation experiments illustrated that PAMS effectively depressed the dolomite flotation whereas it exhibited weak influences on the floatability of apatite. It was also found that the reagent scheme of 14 mg/L PAMS and 100 mg/L NaOl could effectively remove dolomite from apatite at pH 9.00.For dolomite, in the presence of CaCl 2, the solubility of metal ions was increased, especially for Ca 2+. The Ca and Mg sites exposed on the dolomite surface, increased the NaOL adsorption, thus, enhancing the dolomite flotation. However, the formation of Ca(H 2 PO 4) 2 species on fluorapatite surface inhibit its flotation.Effects of common ions on the flotation of fluorapatite and dolomite
