silicon (27.7%). Iron is third at about 5%. Metallic aluminum is not found in nature; it occurs in the form of hydrated oxides or silicates (clays). The principal ore from which aluminum is extracted is called bauxite after the town of Les Baux in southern France where the ore was originally discovered. Bauxite occurs mainly in the tropics and in
The ore of a metal is actually a compound. It is frequently the oxide of the metal, e.g. an iron ore is the compound iron oxide, but it can also be other compounds. The more reactive a metal is, the more difficult it is to extract from its ore. Metals with quite a low reactivity can be extracted by roasting the ore in air.
in aqueous solution. In this method, the crushed ore is allowed to dissolve in a suitable solvent, the metal present in the ore is converted to its soluble salt or complex while the gangue remains insoluble. The following examples illustrate the leaching processes. Cyanide leaching Let us consider the concentration of gold ore as an example.

Iron is an element that has the chemical symbol, Fe. It is a metal that has been used since prehistory, by the Ancient Egyptians and Sumerians as early as 4000 B.C. These ancient peoples were able to get pure iron from meteorites that fell to the earth, and they used it in the tips of weapons and spears because of its strength and durability.

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.

Deals with extraction of metals from its naturally existing ore/minerals and refining them Minerals: Inorganic compounds with more than one metal in association with non-metals like S,O,N etc. Naturally existing minerals are sulphides, oxides, halides like: Hematite (Fe2O3), Magnetite (Fe3O4), Chalcopyrite (CuFeS2), Dolomite
What is iron ore? Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.
