Abstract

The studies results on the reduction firing of rough titanium-magnetite concentrate of the Gremyakha-Vyrmes deposit are presented. The reduction firing of the briquetted charge was carried out on a coal substrate to obtain granular metal and titanium-vanadium slag suitable for subsequent hydrometallurgical processing with the extraction of titanium and vanadium. Studies on reducing roasting were carried out in the temperature range of 1450-1500 °C at different costs of a solid reducing agent — coke. The coke content influence in the mixture and the reduction temperature on the composition of the resulting titanium-vanadium slag has been studied. As a result of solid-phase reduction of rough titanium-magnetite concentrate, optimal conditions for obtaining titanium-vanadium slag suitable for further processing have been established.
