Abstract: The contents of Fe， TiO₂ and Sc2O3 in a low-grade scandium-containing titanium iron ore in Gansu Province are 10.20%， 4.55% and 55.6 g/t， respectively. The magnetic iron accounted for only 17.90% of the total iron， the iron in the form of ilmenite accounted for 22.02% of the total iron， and the iron in the form of silicate accounted for 52.05% of the total iron. TiO2 in the form of ilmenite accounts for 69.01% of the total titanium， and TiO2 in titanomagnetite accounts for 3.52% of the total titanium. The remaining titanium mainly occurs in silicate minerals that are difficult to be enriched and recovered. The size of magnetite is mainly 0.5~0.04 mm， and the size of ilmenite is mainly 1~0.07 mm. They are closely intermingled with silicate minerals. Scandium is mainly found in dark calcium magnesium minerals （mainly amphibole）. In order to determine the exploitation and utilization technology of the ore， the beneficiation test was carried out. The results show that under the condition of 6~0 mm， the tailings of 29.82% can be removed by ZCLA. Then， under the grinding fineness of -0.074 mm accounted for 81%， the iron concentrate with TFe grade of 60.78%， recovery rate of 13.11%；the titanium concentrate with TiO₂ grade of 47.05%， recovery of 55.74% and the scandium concentrate with Sc₂O₃ grade of 99.0 g/t， recovery of 48.68% can be obtained by one roughing （135.4 kA/m） two cleaning （119.4 kA/m and 119.4 kA/m） low magnetic separation process， and the iron tailings are pre-enriched by one roughing （0.7 T） one cleaning（0.6 T） high gradient high intensity magnetic separation process， and the titanium concentrate with high intensity magnetic separation by sequential return process of one roughing， four cleaning， one scavenging.
