The production of aluminium involves three main stages: mining bauxite ore, refining bauxite to alumina (Al2O3), and then smelting alumina to produce aluminium. Bauxite comes from open mines mainly located in tropical and subtropical regions. On average it takes 4 to 5 tonnes of bauxite to produce 2 tonnes of alumina, yielding 1 tonne of aluminium.

Bauxite mining requires relatively low energy inputs, compared to other steps in the aluminium production process – with less than 1.5 kilograms of fuel oil (mainly in the form of diesel for haul trucks) and less than 5 kWh of electricity consumed per tonne of bauxite extracted.
This makes aluminium an excellent building material - reshaped and repurposed to meet the needs and challenges of different times and products. How it's made. 1. Bauxite mining. Aluminium production starts with the raw material bauxite, which contains 15-25 percent aluminium and is mostly found in a belt around the equator.
