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.

The Umicore and Aurubis recycling plants in Europe utilise ISASMELT™ technology in their highly successful secondary copper plants. These operations treat electronic-waste, metal bearing residues, shredder materials, copper scrap, matte, slag and dusts to …

Leading boiler slag applications are blasting grit, roofing shingle granules, and snow and ice control. Boiler slag has also been used as an aggregate in asphalt paving, as a structural fill, (5) and in road base and subbase applications. (2) The U.S. EPA is presently undertaking a study of power plant wastes prior to disposal by the utility.

Custom-designed for each application, our slag processing plants keeps the maximum environmental impact in mind. At our Metal Recovery Plant, a crushing and magnetic separation process is used to recover the metal contained in iron and steelmaking slag. This can then be effectively reused in the steelmaking process.
