Extraction of Aluminium (Aluminium Ore) - Hall
Aluminium is mostly extracted from its bauxite ore. Dressing of ore: The ore is crushed and pulverized. Concentration of ore. The bauxite ore contains ferric oxide and silica as impurities. It is first concentrated by gravity separation of ferric oxide impurities by the process of magnetic separation. The ore is then concentrated by chemical process.
