The production of aluminum metal from bauxite requires huge amounts of energy much of it electrical while converting bauxite ore to metal, and when reclaiming minedout lands. Aluminum metal can be produced much more efficiently (and economically) from salvaged aluminum, scrap because it requires only 5% as much energy to do so.

Since the loss on ignition of bauxite is high, it is first calcined at high temperatures to convert it to a dense grain consisting mainly of corundum (Al 2 O 3) and mullite (3Al 2 O 2). The most widely used refractorygrade calcined bauxite comes from Guyana and Surinam in South America and, more recently, from China.
