Experimental Study on the Recovery of Apatite from Ore Tailings in Hebei

Abstract:

On the basis of study on the ore property of magnetic ores containing apatite,The experiment results show that a magnetic concentrate having a recovery of 58.04%,a concentrate containing 60.38%Fe and yield of 10.90% after by means of two-stages magnetic separation at a grinding fineness of 75%-200 mesh of the first stage , grinding fineness of 85%-200 mesh of the second stage After the first magnetic separation. Based conditional experiment and open-circuit test, under a grinding fineness of 50%-200 mesh, through a flotation flowsheet of "one-stage rough flotation, three-stage cleaning and one-stage cleaning" with the first magnetotail ,a apatite concentrate with P2O5 33% , The yield of apatite was 10.90% , the recovery of apatite reaches to 85% and can be obtained in which the total iron content is lower than 2%.
