摘要: 采用化学沉淀法对碱性V⁃Mo⁃Al溶液进行分离以逐步回收其中的有价金属V、Mo、Al。通过热力学理论分析与条件实验相结合的方法分别考察了沉淀剂物质的量、温度、pH、反应时间等因素对碱性液中V、Mo沉淀分离的影响。结果表明,以CaCl2沉淀V,当反应温度为80 ℃,CaCl2物质的量为理论物质的量的1.1倍,反应时间为1 h,pH为12.9时,V的沉淀回收率约为95.3%;以Ba(OH)2沉淀Mo,当温度为80 ℃,Ba(OH)2物质的量为理论物质的量的2.5倍,反应时间为60 min时,Mo的沉淀回收率达到99.6%。

Abstract: Chemical precipitation method was applied in for separation and recovery of valuable metals molybdenum, vanadium and aluminum from alkaline V⁃Mo⁃Al solution. By the theoretical calculation and conditional experiments, the effects of precipitating agent dosage, temperature, pH value and deposition time on the precipitation separation of molybdenum and vanadium in alkaline solution were investigated detailedly. The results showed that when CaCl2 was used for vanadium precipitation, the reaction temperature was 80 ℃, the addition of CaCl2 was 1.1 times of the theoretical addition, the time was 1 h, and the pH was 12.9,over 95.3% of vanadium was precipitation recovered. When molybdenum was recovered by Ba(OH)2, under the optimum conditions of temperature 80 ℃, Ba(OH)2 dosage 1.1 times the stoichiometric amount, reaction time 60 min,the precipitation rate of molybdenum was up to 99.6%.
