A kind of low-grade ilmenite from Gansu province with Fe grade of 12.23% and TiO2 grade of 3.80% was studied.In view of the occurrence state and percentage of Fe and Ti in the ore and acute shortage of water in the mining area,a combined technical solution of "pre-concentration for tailing discarding by dry medium-intensity magnetic separation-iron separation by fine grinding and low-intensity magnetic separation-titanium separation by combination of high-intensity magnetic separation with flotation" was designed.The effects of relevant factors(ground particle size and magnetic induction intensity,etc.) on test results were investigated.Based on the optimal technical condition,a full process of closed-circuit test was carried out.The obtained iron concentrate had a Fe grade of 60.57% and titanium concentrate had a TiO2 grade of 46.15%,and the recovery rates of Fe and Ti reached 35.14% and 66.19% respectively,realizing efficient and comprehensive recovery of iron and titanium resources in the ore.
