The influence of Ce3+ in the sodium oleate system on the flotation of fluorite and calcite was investigated by flotation test, zeta potential measurement, solution chemistry study and X-ray photoelectron spectroscopy analysis. The results reveal that in the sodium oleate system, Ce3+ with a low concentration exists on fluorite surface in the form of CeF3·0.5H2O(s) under acidic and neutral conditions, therewith, fluorite can be activated to generate more active sites for the adsorption of sodium oleate. Meanwhile, Ce3+ can be adsorbed onto calcite in the form of Ce2 (CO3)3·8H2O(s). There are more active sites generated as well, but calcite may be depressed as the hydrophilic nature of Ce2 (CO3)3·8H2O(s) and the spatial site barrier effect of crystalline water hinder the adsorption of sodium oleate. In alkaline pulp, Ce3+ is mostly precipitated to form Ce(OH)3(s) and depresses both fluorite and calcite as Ce(OH)3 (s) can consume sodium oleate and reduce its adsorption on both minerals.
