摘要：

In this work, the simultaneous extraction of two metals was carried out in both batch and continuous flow operations with single- and two-stage mixer-settlers. The loaded organic solutions obtained by extraction were then scrubbed with hydrochloric acid to examine the effect of scrubbing on the purification of the solutions. The results of extraction of two metals in both batch and flow operations agreed well with prediction using data for single-metal extraction. Scrubbing of loaded organic solution with hydrochloric acid removed 98% of vanadium and only 1-8% of molybdenum, thus increasing greatly the purity of the solution.
