FIELD: chemistry.
SUBSTANCE: invention relates to a method of extracting vanadium, titanium and iron from a concentrate based on vanadium-titanium-iron in a single step. Proposed method comprises the following stages. (1) Concentrate based on vanadium-titanium-iron is mixed and burnt together with an additive and reducing agent, wherein vanadium-containing cast iron and vanadium enriched slag are obtained. (2) Vanadium-titanium-enriched slag is leached in water and filtered, wherein vanadium-containing solution and titanium slag are obtained. Three products are produced, namely, vanadium-containing cast iron, vanadium-containing solution and titanium slag.
EFFECT: technical result is low capital investment, low production cost, reduced environmental pollution.
