| Abstract: | A new direct-reverse flotation process was used to beneficiate the collophanite in Hunan Province,according to its low P2O5 grade only 15.11%,high MgO grade reaching 8.82% as well as fine particle size.Through tests of grinding,direct floation single factor,reverse flotation single factor,open test of direct-reverse flotation and close test of directreverse flotation,its final concentrate yield is 33.45%,P2O5 grade is 30.74%,P2O5 recovery is 63.48%,MgO grade is 1.05%,which reaches the second standard of aci... |
