Iron is a mineral, forming naturally over geological periods in the ground and within rocks. It is one of the most commmon elements on earth, comprising About 5 per cent of the earth´s crust.
Rock containing iron ore often date to more than 2,500 million years old. It is the key ingredient in the production of steel.
HOW IRON IS MINED
Explosives are used to blast through surface rock to access iron ore deposits below the ground. Haul trucks transport the ore to crushing plants, where the ore is crushed into smaller pieces of varying sizes. Crushed ore is then classified into different sizes based on customer specifications. The ore is next transported via reail to ports for shipping to overseas customers or smelters. Iron ore usually ends up in blast furnaces and steel mills, where it is turned into iron and steel through smelting and refining.
HOW IRON IS PROCESSED
Iron ore is smelted in blast furnaces to produce pig iron. In a blast furnace, coke and ore are fed through the top of the furnace while heated air is blasted into the bottom of the furnace at temperatures of around 2000º C.
The chemical reactions that take place as the ore and coke move down creates molten metal and slag floats on top of the more dense molten iron. Iron and Slag are tapped off separately from the blast furnace. Once cooled, the iron is called pig iron. Pig iron is not pure iron as it has 4 to 5 per cent carbon in its make up. Pig iron is used to produce steel or commercialy pure iron (wrought iron) through further smelting and refining in furnaces and converters.
