钒钛磁铁矿生产海绵钛的工艺研究

Vanadium titanium magnetite in the production of titanium sponge process research

我国钒钛磁铁矿储量丰富,已探明储量98.3亿吨,远景储量达300亿吨。为了更好的利用我国钒钛磁铁矿资源,经过多次实验室试验和工业试验,找到了利用钒钛磁铁矿经熔盐氯化制取粗四氯化钛,再通过蒸馏、精馏得到精四氯化钛,最后通过精镁还原、蒸馏制取海绵钛的生产工艺,用此熔盐氯化法工艺生产的最终产物品质优异。

Vanadium titanium magnetite is abundant in our country, has proven reserves ot 9.83 bllhon tons, the prospective reserves of 30 billion tons. In order to better use of vanadium titanium magnetite resource in our country, after many laboratory test and industrial test, found the use of vanadium titanium magnetite by the molten salt chloride from coarse titanium tetrachloride, pure titanium tetrachloride is obtained by distillation, distillation again, at last, by pure magnesium reduction, distillation of preparing titanium sponge production technology, excellent quality in the production of the final product.
