  • Flotation of lowgrade phosphate oreScienceDirect

    In the light of the above, lowgrade phosphorites P 2 O 5 below 2025% must be concentrated prior to their industrial enrichment. The techniques generally applied for this purpose are: calcination, when the ore has low or average carbonate content, and flotation, when the ore has a high carbonate content and siliceous gangue.
