Nickel processing Extraction, Refining, Alloying: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of highertemperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production.

EXTRACTING IRON FROM IRON ORE USING BLAST FURNACE: Extracting iron from its ore requires a series of steps to be followed and is considered as the penultimate process in metallurgy. The steps need the ore to be concentrated first, followed by the extraction of the metal from the concentrated ore after which the metal is purified.

Download. Iron (Fe) is a metallic element that constitutes % by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.

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