How aluminium is produced

The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide - Al 2 O 3, - a white powder.The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today. Get price

Bauxite

Bauxite is the main raw material used in the commercial production of alumina (Al 2 O 3) and aluminium metal, although some clays and other materials can be utilised to produce alumina.Bauxite is a heterogeneous, naturally occurring material of varying composition that is relatively rich in aluminium.

Salty About Coastal Construction? Use the Right

Aluminum. Salt can break down the protective oxide that forms on aluminum's defensive oxide layer. Structural aluminum can sustain fatigue failure as a result of surface pitting. You can opt to specify high-strength alloys that are more resistant. Some tempers of 2XXX and 7XXX are not for coastal life -- they'll corrode and crack. Get price
