2016.5.25 The extraction and recovery process of vanadium as a by-product from the tailings of a uranium processing plant poses many problems. In this study vanadium is recovered from impounded resin-in-pulp tailings and from the current tailings of a uranium plant which did not include a circuit for vanadium recovery in its initial design.
