ABSTRACT:
The amount of carbonate mineral impurities is reduced in aqueous phosphate rock slurry by (a) conditioning the slurry with an effective amount of CO.sub.2, (b) adding an effective amount of an anionic collector to the slurry and (c) subjecting the slurry to a froth flotation process whereby the carbonate mineral impurities are concentrated in the froth. The CO.sub.2 acts to depress flotation of phosphate minerals relative to the carbonate mineral impurities.
