Extraction of aluminum involves the process of electrolysis of alumina.

• Aluminum is extracted from its ore, bauxite, through the Bayer process.

• The extracted alumina is then converted into aluminum through the Hall-Héroult process.

• Electrolysis is used to separate the aluminum from the oxygen in alumina.

• The process requires a large amount of electricity and is energy-intensive.

Alumina is extracted from bauxite through a process called the Bayer process.

• Alumina is the primary component of aluminum production.

• The Bayer process involves crushing the bauxite ore, mixing it with sodium hydroxide, and heating it in a pressure vessel.

• The resulting solution is filtered to remove impurities, leaving behind alumina which is then processed into aluminum.

• Alumina is used in a variety of industries includ
