The high-magnetic titanium rough concentrate with TiO2 grade of only 11.91%is obtained by gravity separation-low intensity magnetic separation-high intensity magnetic separation from the iron tail-ings of an ilmenite concentrator in Xinjiang.In order to efficiently recover the low-grade high-magnetic tita-nium rough concentrate,the flotation test is carried out by using the self-developed new combined collector WY-1.The test results show that with sulfuric acid and water glass as the regulator,lead nitrate as the acti-vator,and WY-1 as the combined collector,a good index of TiO2 grade of 46.87%and recovery of 77.99%is obtained by the closed-circuit test of desulfurization,one roughing,one scavenging and three cleaning of low-grade high intensity magnetic rough concentrate.The new combined collector WY-1 has a good collect-ing effect on low-grade ilmenite,and can effectively improve the recovery rate of low-grade ilmenite re-sources.
