• Vanadium Extraction Process

    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, capital expenditures

  • Vanadium processing Britannica

    Vanadium processing, preparation of the metal for use in various products.. Vanadium (V) is a grayish silver metal whose crystal structure is a body-centred cubic (bcc) lattice, with a melting point of 1,926° C (3,499° F). The metal is used principally as an alloying addition to high-strength low-alloy (HSLA) steels and, to a lesser extent, in tool steels and iron and steel castings.
