Abstract

Abstract

Vanadium-titanium magnetite has its unique characteristics like containing many valuable elements, complex phase structure and close intergrowth of iron and titanium, as well as the difficulty of full comprehensive utilization. In this paper, the phase change of vanadium-titanium magnetite reacted with Na₂CO₃ at high temperature were studied, and the influence of temperature and biomass sawdust on the metallization rate of the reduction product was discussed. The results show that the addition of Na₂CO₃ can promote reaction of vanadium-titanium magnetite with H₂ and favour reducing the iron-titanium oxide in vanadium-titanium magnetite with H₂. Increasing the temperature and addition of biomass sawdust both are beneficial to reduction of vanadium-titanium magnetite by H₂. The is. When the reducing temperature is 1100 ℃, the metallization rate of vanadium-titanium magnetite can reach 80.22%, and the metallization rate can be increased to 84.47% by adding biomass sawdust under same conditions. The use of H₂ to reduce vanadium-titanium magnetite while adding biomass sawdust is expected to achieve high-efficiency enrichment of iron.
