ABSTRACT:
There is disclosed an improved process of beneficiating phosphate-containing ores. The process comprises stabilizing a hydrocarbon oil, normally used in a conditioning step to improve separation of the ore from the solid contaminants in a flotation step, upstream of the conditioning step. The oil is stabilized by conducting it to a pre-stabilization step wherein it is mixed with at least one fatty acid or saponified fatty acid and water to form a stable, homogeneous emulsion. The emulsion is then transferred to the conditioning step wherein it is mixed with the phosphate-containing ore.
