Read MoreBench scale beneficiation studies were made on Idaho dolomitic phosphate rock using the TVA carbonate flotation process. The process used diphosphonic acid as a phosphate mineral depressant and fatty acid as a carbonate mineral collector. Silica was subsequently rejected as float using an amine collector, with phosphate product recovered as the sink fraction. Two
Read MoreFor effective beneficiation of phosphate rock, a surface conditioner must be added to the slurry prior to agglomeration. Effective surface conditioners include oleic acid, fatty acids, and high molecular weight organic acids. These surface conditioners activate the surface of the phosphates. For optimum results, the pH of the slurry should be ...
Read More1999-3-26 · The process of mining and beneficiation to produce one ton of commercial rock phosphate (32 % P2O5) requires approximately 0.9 GJ/tonne rock or 2.9 GJ/tonne P2O5. If the rock is calcined the total energy requirement is doubled (Ullmann, vol. A 19, 1991). References: BAT N° 4 (1995).
