Jan 07, 2018· Aluminium often exists as a compound primarily in the form of aluminium oxide (Al 2 O 3), or otherwise known as alumina. Other sources of aluminium include aluminium phosphate rock and high alumina clays. Bauxite is the primary feedstock for an alumina refinery to extract aluminium oxide using the Bayer process.

The extraction of aluminium involves two steps that is, purification of bauxite by Baeyer's process and electrolysis of alumina. 1. Purification of bauxite by Baeyer's process In the Baeyer's process, the bauxite ore is heated with concentrated NaOH solution under pressure (Aluminum is purified by leaching method). The alumina dissolves as sodium meta aluminate.

Aluminum (or Aluminium, if you're not from the US) is an abundant element within Earth's surface— but getting it out of the ground is an arduous process, requiring heavy machinery to plow up acres and acres of land. Fortunately, the environmental impact of that process can be somewhat balanced out by postmining rehabilitation, efficient recycling, and generally reducing our consumption.

Extraction Process of Aluminium from Bauxite Ore

Extraction Process of Aluminium from Bauxite Ore. Aluminum is the most abundant metal in the earth's crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes.
