Quick Facts
Approx 25% of the earth's crust is made up of metal ores. Bauxite is the most common ore (aluminium is made up of this). Metals can easily be recycled (due to usually a low melting point).

How is a metal created?
The raw material is extracted from the ore through a combination of crushing, smelting or heating with the addition of chemicals and huge amounts of electrical energy. The final product can lead to a pure / refined metal in its stock form.

Ferrous Definition
A metal containing mostly iron and carbon. Ferrous metals are magnetic and will rust.

How to create Aluminium? pt1
Aluminium starts off with its raw material bauxite (found in the belt surrounding the equator, clay soil). Alumina is extracted from the bauxite through refining - crushing, smelting or heating with the addition of chemicals and huge amounts of electrical

How to create Aluminium? pt2
https://www.hydro.com/en-GB/about-aluminium/how-its-made/
There are three different raw materials needed to make aluminium, aluminium oxide, electricity and carbon. Electricity runs between an anode and cathode, this release CO2. This results in now a liquid from of aluminium that can be cast into extrusion ingo

How to create Steel
To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added (lime and coke). The steel in its molten form is cast into cooling moulds. This allows the steel to become ha
