A Process For Selective Separation Of Phosphate Minerals From Other Minerals Using Alkylimino Bismethylene Phosphonic Acid Based Depressant
Abstract: An improved method is disclosd for separation of phosphate minerals, particularly apatite [Ca10(PO4)6(F,OH)] from other minerals, particularly from high dolomite [(Ca,Mg)CO3] containing phosphate ores. The method consists of conditioning the aqueous pulp of the mineral mixture with the depressant at an acidic pH of 5.5 to 7. The aqueous pulp is further conditioned with a collector and is subjected to froth flotation. The impurities or unwanted minerals are collected in the froth phase, which are removed. The phosphate bearing minerals are retained in the flotation tailings. The depressant molecule used is a phosphonic acid compound of the formula. wherein x is between 2-12 carbons and R is a cation, typically hydrogen or an alkali metal. The collector is generally a fatty acid such as oleic acid.
