The process mineralogy and separation feasibility of an ilmenite ore from Xinjiang were comprehensively studied to recover iron and titanium resources from the gravity separation concentrate. The process mineralogy results show that the valuable minerals therein include ilmenite, manganese-bearing ilmenite, titanium-bearing magnetite and magnetite, while the gangue minerals therein are predominantly tremolite, riebeckite, garnet and sphene. After one stage of grinding, iron minerals were collected with one stage of low intensity magnetic separation. Then, two stages of high intensity magnetic separation were adopted to recover titanium minerals. The titanium rough concentrate was treated by a flotation for desulfurization and a flotation process consisting of one stage of roughing, one stage of scavenging and four stages of cleaning. The whole process produced an iron concentrate grading 63.93% TFe at 69.11% recovery, presenting a good separation index, and a titanium concentrate was obtained with grade of 32.59% TiO2 at 28.04% recovery. It is found that low TiO2 content and high content of iron-bearing silicate gangue minerals are the main factors affecting the ilmenite beneficiation indicators.
