The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulfide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag. Iron in Chalcopyrite is removed as Iron silicate slag. Most of the sulfur in Chalcopyrite turns into Sulphur dioxide (SO2).

Iron ore is used to make iron and steel eg haematite and magnetite. Iron is produced (extracted) in a blast furnace by reducing iron oxides with carbon and it is the carbon that removes the oxygen from the iron oxides – the carbon is known as the reducing agent. Coke is a cheap and readily made reducing agent.

Concentration of the ore. But the conversion of FeO into Fe 2 O 3 will prevent the formation of FeSiO 3. Thus the mass of the ore becomes porous causing the increase in the effective surface area. Smelting in the Blast furnace: Blast furnace is a shaft furnace made of steel plate of 2030 in with diameter.

Jul 21, 2014· Uses of iron made by blast furnace. Blast furnace iron is not very pure (96% iron, 4% impurities). The impurities make it brittle (cracks easily when bent) and so it has limited uses. Most of the iron produced is converted into steels. Steels are alloys, that are carefully controlled mixtures of iron, carbon and other elements.
