采用溶剂萃取法从焙烧石煤和软锰矿共浸液中选择性分离提取钒(V)和锰（II）的新工艺，研究了钒(V)和锰（II）的萃取效果，并对多项工艺条件进行了优化。同时进行了逆流仿真实验，验证了实验结果。结果表明：以5% (V / V) N235和5% （V / V）仲辛醇为溶剂，初始水溶液pH为3.0，O/A相比为1.0，共3个逆流萃取阶段，钒(V)提取率为99.21%；在0 /A相比为1.0的条件下，用20 wt.%的NH4Cl进行三级逆流实验，可以完全剥离钒(V)。提出了回收钒(V)和锰（II）的工艺流程。
Based on the novel technology for selective separation and extraction of vanadium (V) over manganese (II) from co-leaching solution of roasted stone coal and pyrolusite using solvent extraction, the extraction effect of vanadium (V) and manganese (II) has been studied and many technical conditions have also been optimized. Meanwhile, countercurrent simulation experiments were conducted to verify the results of the experiments. The results indicated that with three countercurrent extraction stages, 99.21% vanadium (V) was extracted using 5% (v/v) N235 and 5% (v/v) secondary octyl alcohol at initial aqueous pH of 3.0 and O/A phase ratio of 1.0. Vanadium (V) could be completely stripped after three-stage countercurrent experiments with 20 wt.% NH4Cl at O/A phase ratio of 1.0. The process flow sheet for the recovery of vanadium (V), as well as manganese (II), was proposed.
