ABSTRACT:
This invention relates to apatite flotation reagents which can be used simultaneously with silica collectors in a coflotation process without problems of incompatibility between the apatite flotation reagent and the silica collectors. The apatite flotation reagent includes soya lecithin. The soya lecithin can be used as an apatite collector by itself or can be blended with a phosphate ester, preferably an ethylene oxide modified alcohol based phosphate ester. In an additional embodiment, the apatite flotation reagent can be solely comprised of a phosphate ester, preferably an ethylene oxide modified alcohol based phosphate ester.
