· Magnetite and hematite are iron oxides however, the extraction of iron from an iron oxide involves a series of steps that begins when mined iron ore is crushed into smaller pieces by a crusher and then washed.

At the bottom of the furnace the iron ore is chemically reduced. The blast reacts with the coke carbon dioxide and carbon monoxide are formed at temperatures of up to 2000 °C. The carbon monoxide removes the oxygen from the iron ore resulting in pig iron production. Slag is formed from the other ore components and the additions. Casting bay

The slag is lighter than molten and to floats on the surface of the . The formation of prevents the oxidation . d. Zone of Reduction:-This is the most important zone and has temperature of 600-700 0 c. In this zone Fe 2 O 3 is reduced to by co in three steps. 3Fe 2 O 3 + CO → 2Fe 3 O 4 + CO 2

The extraction of iron from its ores is quite a technical process. The iron ore is first 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.

This process is used for the extraction of copper from low grade sulfide ore. In this process, the crushed and ground ore in bulk about 100,000 tons is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides. The process is completed in about one year.
