Study on Comprehensive Recovery of Valuable Elements in the Tail Slag from Titanium Tetrachloride Refining by Vanadium Removal with Copper Powder AITranslate
Abstract AITranslate
The tail slag from TiCl4 refining by vanadium removal with copper powder is of complex composition,easy to hydrolyze and generate corrosive gas,which seriously pollutes the environment,and the valuable elements are difficult to recover.A new method for recovering copper and other valuable elements was studied according to the characteristics of the compounds contained in the tail slag of TiCl4 refining by vanadium removal with copper powder.It consists of chlorination in NaCl-KCl molten salt,oxidation leaching of CuCl2 with NaOCl,alkaline dechlorination with NaOH,acid leaching with H2SO4,and preparation of CuSO4 by cooling crystallization.CuSO4·5 H2O product with the quality meeting the national and industrial requirements was obtained by washing,filtering and drying of CuSO4·5 H2O crystal.The recovery rate of copper reaches 94.5%.After chlorination process,titanium and vanadium can be separated and recovered by fractional distillation from the distilled mixture of TiCl4 and VOCl3.The waste NaCl-KCl molten salt and NaOCl,which are by-products in the production of titanium sponge,are used as raw materials to reduce the production cost.The filter residue and washing water produced by this process can be reused in the process and titanium sponge production.Therefore,there is no waste generated in this process.
