Bauxite The principal ore of aluminum. Bauxite Used for Aluminum Production Bauxite is the principal ore of aluminum The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process In the Bayer Process the bauxite is washed in a hot solution of sodium hydroxide which leaches aluminum from the bauxite
Bayer process - Wikipedia
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al2O3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to aluminium metal.
Mining and Refining – Process - World Aluminium
The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production.
