Based on research status of comprehensive utilization of titanium rich blast furnace slag(BF slag)in Pangang,the technical approach of "Fe recycling by magnetic separation-dealuminizing by activation-Ti leaching by acidolysis "was proposed to recycle valuable elements including Fe,Al,and Ti in the slag.Mineral phases and iron occurrence in the Ti-bearing BF slag were analyzed by means of XRD and metallographic microscope.The technologies of single low-intensity magnetic separation and staged grinding and low-intensity magnetic separation were adopted respectively for iron recycling.The results show that the main mineral phases of the BF slag are perovskite,diopside and spinel,and metallic iron existing as globularity mostly distributes in the diopside.Except grinding cost saving,the utilization of the staged grinding and low-intensity magnetic separation also boosts an iron concentrate of 63.5% with a recovery rate of total iron at 64.2%,which creates favorable conditions for subsequent dealuminizing and Ti leaching.
