Experimental Research of Fluorite Flotation Separation

Abstract:

Grade of fluorite in this test is 30.95%,containing CaCO3 0.86%. On the base of much experiment research, such as grinding fineness test, pH test, agent dosage test and so on, the optimum conditions were: grinding fineness for first stage is -0.074mm 65%,pH=9, sodium silicate 0.8 kg/t and oleic acid 0.7 kg/t . The result of tests showed that the grade of CaF2 concentrate, recovery and productivity are 95.38%, 63.42% and31.20% by adopting a circuit of one rough flotation and seven concentrating with grinding fineness -0.043mm90.3%.
