Extraction of Metals. What is a Metal Ore?. A solid element or compound which occurs naturally in the Earth's crust is called a mineral.A mineral which contains a high enough percentage of a metal for economic extraction is called a metal ore. Economic extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling the metal.
The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.
EXTRACTION OF METALS Occurrence • ores of some metals are very common (iron, aluminium) • others occur only in limited quantities in selected areas • ores need to be purified before being reduced to the metal this adds to the expense • high grade ores are therefore cheaper to process.

Procedures for Metal Extraction. Concentration of Ores: Ores may be concentrated either by (i) Washing away the earthy materials in a stream of water in order to leave behind the heavier ores as is the case with tin ore or by (ii) Froth flotation where the ores are churned up with oil and water to form froth. This froth which contains the ore is skimmed off by blowing air.
