对海绵钛厂Ti Cl4精制工艺尾渣的回收利用进行了研究。在对尾渣元素组成和物性分析的基础上,提出了高温煅烧尾渣制备钒渣的工艺。对煅烧温度、物料粒度以及煅烧时间等进行条件试验。结果表明,在煅烧温度≥600℃,煅烧时间大于2 h条件下,可将尾渣制备成TV在8%~12%、Cl含量小于0.3%的钒渣,V收率达到95%,Cl逸出率达到99%。 The recovery and utilization of the tailings of Ti Cl4 refining process was studied. Based on the analysis of elemental composition and physical properties of tailings, a process of preparing vanadium slag from high temperature calcined tailings was proposed. The calcination temperature, particle size and calcination time were tested. The results show that the tailing slag can be prepared into vanadium slag with TV content of 8% ~ 12% and Cl content less than 0.3% at a calcination temperature of ≥600 ℃ and a calcination time of more than 2 h. The V yield reaches 95% The rate of 99%.
