Experimental Study on Low Temperature Flotation Recovery of Apatite from a Magnetic Tailings

Abstract

An experimental research on comprehensive recovery of associated apatite from certain iron tailings in China was carried out. The phosphorus flotation is realized at low temperature through the application of the new, more efficient AW series collector. The test results showed that the concentrate whose P2O5 grade was 33.50%,recovery was 92.18% was obtained for the tailings whose P2O5 grade was 3.05% by one roughing under the pulp temperature of 15°C, thus realizing an effective recovery of apatite from the tailings.
