ABSTRACT:
A process for beneficiating phosphate containing ores, wherein promoter reagents are added to the ore slurry prior to the addition of collectors and depressants for flotation of the carbonate and silica components. The promoters aid in increasing the rejection of the magnesium present during carbonate and silica flotation steps and recovery of phosphates, so that acceptably low magnesium levels for phosphoric acid production can be achieved in a phosphate concentrate in a single rougher stage. Preferred promoters include sodium carbonate and ammonium hydroxide.
