First the aluminium ore needs to be mined, then the bauxite is refined into alumina (aluminium oxide). Large amounts of electricity are used to smelt the alumina into aluminium metal. Properties

  • Aluminum: How It's Made

    2021-11-1 · Alumina, commonly known as aluminum oxide, is extracted from Bauxite Ore done by grinding ore and mixing with Caustic Soda (Sodium Hydroxide) called Slurry. The slurry is treated in a high-pressure container and heated to 230-250 degrees, making alumina. When refined from Bauxite, alumina is a white powder, appearing to look like table saltHow Is Aluminum Made? » Science ABC,2019-12-12 · Bauxite consists of 45-60% aluminum oxide, along with various impurities, such as sand, iron and other metals. Although some bauxite deposits are hard rock, most consist of relatively soft dirt that is easily dug out from open-pit mines. Australia produces more than one-third of the world’s supply of bauxite.
