Iron Production
The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first ...
THE BLAST FURNACE
As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed.

Nickel processing
Nickel concentrates may be leached with sulfuric acid or ammonia, or they may be dried and smelted in flash and bath processes, as is the case with copper. Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel.In the next …
Extraction of Aluminium
The Hall-Heroult process is widely used in the extraction of aluminium. In Hall-Heroults process, pure Al 2 O 3 is mixed with CaF 2 or Na 3 AlF 6. This results in lowering the melting point of the mixture and increases its ability to conduct electricity. A steel vessel with a lining of carbon and graphite rods is used.
