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.

As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron. The stock level is constantly 'topped up'. Molten iron ore is 'tapped' at the bottom of the blast ...

Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things – nails, wire, car bodies, ship building, girders and bridges amongst others.

Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45).Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm.

Iron ore mining is relatively simple compared to other minerals and metals that require underground tunnels and complex chemical-drive processes, like gold. Iron ore is generally sourced from open pits on the planet's surface and typically requires only crushing before it is ready for the smelter. Like most mining, It all starts with a bang.
