Aluminum production, and the bauxite and alumina that make up the process chain, is essentially a 20th century industry. Again, according to the BGS, in 1915, the entire world produced somewhat more than 500,000 mt of bauxite, with France and the USA accounting for more than 97% of .
Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. As of 2010, approximately 70% to 80% of the world's dry bauxite production is processed first into alumina and then into aluminium by electrolysis.
Bauxite mining requires relatively low energy inputs, compared to other steps in the aluminium production process – with less than 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.
