    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. Since the vanadium content is quite low

  • Vanadium element extraction methods – smelting Vanadium element extraction methods – smelting

    The general process of obtaining vanadium from its ores is in the form of vanadium pentoxide (V 2 O 5) through performing a variety of processes like smelting, leaching, and roasting after which the pentoxide is reduced to ferrovanadium or vanadium powder. Very pure vanadium metal resembles titanium with respect to certain physical properties of being corrosion resistant, hard, and steel gray in

  • Vanadium processing | Britannica Vanadium processing | Britannica

    Vanadium is extracted from carnotite as a coproduct with uranium by leaching the ore concentrate for 24 hours with hot sulfuric acid and an oxidant such as sodium chlorate. After removal of solids, the leachate is fed into a solvent extraction circuit where the uranium is extracted in an organic solvent consisting of 2.5-percent-amine–2.5-percent-isodecanol–95-percent-kerosene

    Aug 30, 2015 Fig. 1 indicates that initial solution pH is an important factor that influences vanadium extraction. The extraction of vanadium increased from 49.4% to 80.1% as the initial solution pH increased from −0.24 to 0.65. A slight effect on vanadium extraction was observed when the initial solution pH was 0.65–0.88
