An Approach to Beneficiation of Apatite Ore of Purulia

Direct flotation Direct flotation of apatite involves the interaction of grind variation as well as reagents optimisation. Different reagents like emulsified oleic acid is used for flotation of apatite, but it has affinity for iron minerals also. Starch is used for suppression of iron minerals and caustic soda as pH modifier. Sodium silicate was used as depressant for siliceous material. In

Effect of calcium concentration on calcite .

In apatite flotation, the Ca 2+ and Mg 2+ ions reacted with the apatite collector (rice bran oil soap), forming insoluble soaps of rice oils, reducing the collector level in the system. Based on these results, limited ion concentrations 20 mg/L Ca 2+ and 30 mg/L Mg 2+ were proposed to ensure the quality of recirculating water without impairing the flotation process.
