  • Carbonate Phosphate Separation by Flotation

    Selective fatty acid flotation of carbonate gangue from sedimentary apatites was achieved under acidic pH’s without a specific apatite depressant and without conditioning the pulp with the collector. Concentrates (35-38% P2O5, 0.8-1% MgO) with high recoveries (80-85%) were produced from Indian and Chinese dolomitic ores. The calcareous and/or dolomitic-siliceous phosphate ores of South ...
