The recycle of slag produced during the refining process of TiCl4 in the sponge titanium factory was studied.Based on the analysis of the element compositions and physical properties of the slag from the refining process of TiCl4,a process of preparing vanadium slag by high temperature calcination of the slag was proposed.The experimental conditions of the calcination temperature,calcination time and the material particle size were studied.The results show that vanadium slag with 8%~12% of TV content and less than 0.3% Cl can be obtained by calcination of the slag from the refining process of TiCl4 at T ≥ 600℃ for more than 2 h.The recovery rate of V is 95% and the emission rate of Cl reaches 99%.
