摘　　要：对四氯化钛铜丝除钒精制过程中产生的废弃物,采用酸碱联合法回收其中的铜和钒。考察了关键的碱处理及盐酸沉钒过程的影响因素。实验结果为:在碱处理溶液pH12.0～13.0,碱处理温度60℃,碱处理时间1h,沉钒溶液pH1.0～1.5,沉钒温度60℃,沉钒时间1h的条件下,铜和钒的回收率分别达到90%和75%以上,获得的阴极铜和五氧化二钒的产品质量均达到国家标准。By the combined process of alkali and acid treatment, copper and vanadium were recovered from the waste generated in the refining of titanium tetrachloride for removing vanadium by copper wire. The factors affecting the two key processes of alkali treatment and vanadium-deposition with chloride acid were studied. Under the conditions of alkali-treatment solution pH 12 - 13, alkali- treatment temperature 60 ℃, alkali-treatment time 1 h, vanadium-deposition solution pH 1.0 - 1.5, vanadium-deposition temperature 60 ℃ and vanadium-deposition time 1 h, the recovery rate of copper and vanadium is above 90% and 75% respectively. The product quality of copper and vanadium oxide can meet the national standards.
