Definition Of Extraction Of Metals Metals, save for a few, do not occur free on the earth They are always in their combined state More About Extraction of Metals An ore is a source of metal from which you can economically extract the metal; Metals are generally extracted by the following steps:
1) The galena is roasted (reacts with O2) in order to remove the sulfur component of the metal sulfide  Roasting is a method where a sulfide ore (ie an ore containing PbS) is heated in air which converts the metal sulfide to either a metal oxide or a metal itself 
Existing processes for the recovery of platinum group metals (PGM) from UG-2 ores place stringent requirements with regard to chromite content upon feed material to the plant An alternative hydrometallurgical process for which this is not an issue is proposed that involves reductive roasting of the ore followed by leaching with

Roasting is a metal formation technique most useful for metal sulfid Most iron ores are oxides, which are more suitably converted to metal using the blast furnace Oxygen is good at
In metallurgy, the operation of roasting, as a preliminary to chlorination, has for its object the expulsion of the sulphur, arsenic, antimony and other volatile substances existing in the ore, and the oxidation of the metals left behind, so as to leave nothing (except metallic gold) which can combine with chlorine when the ore is subsequently treated with it in aqueous solution
The process of extracting pure metal from its ore is known as metallurgy Since, the nature of the ore and also the properties of different metals are different, therefore, it is not possible to have the universal scheme which may be applicable to all the metals
