Aluminium Extraction | A* Chemistry

Aluminium Extraction: The main ore of aluminium is bauxite (aluminium oxide). After it is mined, it is first purified by adding it in sodium hydroxide. The impurities do not dissolve and are filtered off. The dissolved aluminium oxide is then precipitated out as aluminium hydroxide by diluting with water.

Cryolite - Wikipedia

Molten cryolite is used as a solvent for aluminium oxide (Al 2 O 3) in the Hall–Héroult process, used in the refining of aluminium. It decreases the melting point of molten (liquid state) aluminium oxide from 2000–2500 °C to 900–1000 °C, thus making the extraction of aluminium more economical.

Extraction of Metals. Extraction of Aluminium. Aluminium ore is called bauxite. Bauxite contains aluminium oxide, water, iron oxide and other impurities. The purified dry ore, called alumina, is aluminium oxide - Al 2 O 3. The alumina must be molten for electrolysis to work, since the ions are not free to move in the solid state.
