Lunar Aluminum Production - Lunarpedia

Lunar Aluminum Production. Since Luna lacks any known deposits of bauxite, the ore most commonly used on earth for aluminum production, anorthite (CaAl 2 Si 2 O 8) is most commonly proposed as a lunar substitute. Anorthite could be separated from the lunar highland material Anorthosite with mechanical methods.

Aluminium production process

ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.

The most abundant metallic element, it constitutes 8.1 percent of Earth's crust. In nature it occurs chemically combined with oxygen and other elements.

Aluminium recycling - Wikipedia

Aluminium recycling is the process by which scrap aluminium can be reused in products after its initial production. The process involves simply re-melting the metal, which is far less expensive and energy-intensive than creating new aluminium through the electrolysis of aluminium oxide (Al 2 O 3), which must first be mined from bauxite ore and then refined using the Bayer process.
