Iron is the most vital metal in human use. It constitutes % of the crust material and holds third position in abundance after silicon and aluminium. It is rarely found in native condition except in meteorites and some eruptive rocks. It enters into large number of rocks forming silicates and is widely available as oxides.

The pig iron was melted in a running out furnace and then run out into a trough. This process oxidised the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough. The product of this process was a white metal, known as finers metal or refined iron.

The extraction of metals and minerals is the fifthlargest industry in the world. The South African mining industry alone employs 800,000 people. Metals need to be extracted from ores before they can be turned into useful products, such as cars or cutlery. For example, iron is found combined with oxygen in ores called . haematite. and . magnetite.

This type of foundry started in 1 060 The primitive smelting of iron was done in extremely hot ovens. The temperature and ventilation in the ovens were controlled. After the iron had melted, the iron would harden and then hammered to get rid of the silt. Afterwards, it was processed and cut into sheets.

Roasting: In this process the sulfide ores are heated to a high temperature in presence of air. Smelting: In this process heat is applied to the ore in order to extract the base metals like silver (Ag), iron (Fe), copper (Cu) etc. Often before roasting, the ore (generally sulfide ores) is partially purified using another important

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.
