The titanium-magnetite ores keep an important place among complex iron-containing ores. Utilization of these ores, comprising ores of Kopanskoe deposit, in steel industry is a serious problem, requiring for its solving enrichment resulting in obtaining iron-vanadium and ilmenite concentrates. A principal flow-chart of titanium-magnetite ores enrichment with obtaining conditional iron-vanadium and ilmenite concentrates elaborated. Results of flotation tests of non-magnetic fraction of Kopanskoe deposit titanium-magnetite ores, which is difficult for concentration. Application of flotation process for Kopanskoe deposit titaniummagnetite ores enrichment, which is difficult for concentration, enables not only to improve the enrichment indices, but considerably simplify the process chain of the plant equipment by excluding a big number of gravitational facilities. It was shown, that ilmenite and rutile flotation is successfully carried out in an acidic environment with the use of oleic acid, kerosene, sodium fluoride, sulfuric acid, foam activator VKP. The elaborated reagent complex provides obtaining conditional ilmenite concentrate. As a result of enrichment by application the elaborated magnetic flotation technology, iron-vanadium concentrate with a mass fraction of iron equal to 63.4 % and titanium dioxide – 4.5 % as well as ilmenite concentrate with a mass fraction of titanium dioxide equal to 45.2% obtained. The elaborated technology can be used for titanium-magnetite ores of Medvedevskoe, Kusinskoe, Chernorechenskoe deposits.
