Despite the plants of the Ural region have significant mining capacities, they are buying raw materials from other regions, therefore the task of wastes minimization is a perspective of supporting their raw materials base. A technology was proposed to increase the quality of titanium-magnetite concentrate, comprising dividing of the ore into two technological grades – a rich and a poor ones following separate crushing and concentration of the grades at separate sections. Due to this technological scheme, the ore is divided into easy-concentrated and hard-concentrated grades at the concentration stage, but not at the stages of preparation to development, mining, transporting and crushing. The advantage of the new technology is the relative simplicity of equipment modernization, since the technological scheme of the ore processing is modified only at the concentration plant. Under laboratory conditions, an iron-vanadium concentrate with iron content of 67.1% and vanadium pentoxide of 0.6% was obtained.
