Abstract: There is a variety kinds of minerals in ilmenite gravity concentrate from Sichuan Panxi Area, metallic minerals mainly including ilmenite, titanomagnetite, gangue minerals mainly including titanaugite, chlorite. Dissemination size of ilmenite is fine, as well as gangue minerals, most of gangue minerals containing iron elements and easy to be slime. To high efficiently separation the ilmenite, beneficiation experiment was conducted. The results show that good separation indexes can be obtained through the technological process of stage grinding-low intensity magnetic removal iron-flotation concentrating titanium-high intensity magnetic separation and extraction. The ore sample was ground to -0.074 mm accounting for 55%， and ferromagnetic iron ore is removed under the condition of magnetic field intensity of low intensity magnetic separation 96 kA/m. Low intensity magnetic tailings are used to separate ilmenite in flotation with sulfuric acid as pH adjuster， sodium carboxymethyl cellulose （CMC） as inhibitor， sodium oleate as collector. The obtained flotation rough concentrate is classified by 0.038 mm， oversize product was ground to -0.074 mm passing 80%. It is combined with the undersize product to remove the -0.014 mm fine mud. Then four cleaning processes are applied on the sand setting. By the closed-circuit flotation test， the flotation indexes of 42.86% titanium grade and 59.79% recovery were obtained. Furthermore， the indexes of closed-circuit concentrate were obtained with 46.77% titanium dioxide grade and 54.38% recovery through high-intensity magnetic separation， which realized the effective recovery of ilmenite resources and can provide the technical assistance for plant development.
