摘要：
In order to produce high-grade titanium dioxide (95% TiO2) directly from a titanium ore using titanium scrap and iron chloride waste, chlorine recovery and selective chlorination processes were investigated. The mixture of titanium scrap and ferrous chloride in carbon crucible and titanium ore in quartz crucible were placed inside gas-tight quartz tube. The experiments were conducted at 1193-1248K. Titanium tetrachloride and metallic iron were produced by the chlorination of titanium scrap in the carbon crucible, and the chlorination ratio of titanium chip was 94.6%. In the quartz crucible, 96.2% TiO2 was obtained under certain conditions by the selective removal of iron from the ore because of the reaction with the generated TiCl4. The iron removal ratio of titanium ore was 98.2%. Therefore, the feasibility of the effective use of titanium scrap and iron chloride waste for upgrading titanium ore was demonstrated in this study.
