Vanadium Extraction Process Mineral Processing Metallurgy

The extraction and recovery process of vanadium as a byproduct from the tailings of a uranium processing plant poses many problems. In this study vanadium is recovered from impounded resininpulp tailings and from the current tailings of a uranium plant which did not include a circuit for vanadium recovery in its initial design. Since the vanadium content is quite low, capital expenditures ...
