Leaching of vanadium from the secound stage duplex process converter slag

Abstract

Usually hydrometallurgical recycling of «poor» (<5 wt. %) vanadium slags, ashes of TPP, brown coal, oil sludge supposes acidic leaching. In the process of acidic leaching a lot of impurities of metals go into solution together with vanadium. So the present work is devoted to the study of processes of the selective leaching vanadium from slag and precipitation of vanadium compounds from the acidic leaching solution.
