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.
