Effects of Ca2+, Mg2+, SO42- and PO43- on the flotation behavior and surface properties of dolomite and fluorapatite were studied by performing tests of pure mineral flotation, Zeta potential and contact angle. The results show that dissolved ions can significantly change the floatability, surface electricity property and surface wettability of these two minerals. Ca2+, Mg2+, SO42- and PO43- can reduce their contact angles, weaken their hydrophobicity and decrease the flotation recovery. Ca2+ and Mg2+ can increase, while SO42- and PO43- can decrease the Zeta potential of dolomite and fluorapatite. These results can be used as reference for removal of harmful ions in phosphorite ore processing.
