    For every 1 ton of iron ore concentrate produced approximately 2.5–3.0 tons of iron ore tailings will be discharged. Statistics show that there are 130 million tons of iron ore discharged every year. If, for example, the mine tailings contain an average of approximately 11% iron there would be approximately 1.41 million tons of iron wasted annually. These tailings are also high in other useful metals such as copper, nickel, and cobalt, and they can be used for road-building materials like pavement and filler an

    The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source – as you will see below.

    MiningPurificationReductionAlloysResourcesThe first step in metal production always involves some form of mining. Mining refers to the process of removing the metal in its free or combined state from Earth’s surface. The two most common forms of mining are surface and subsurface mining. In the former case, the metal or its ore can be removed from the upper few meters of Earth’s surface. Much of the world’s copper, for example, is obtained from huge open-pit mines may range in depth to as much as nearly a 0.6 mi (1 km) and in width to as much as mo
