The Hall-Héroult Process is an industrial method used to extract aluminum from its ore, primarily bauxite. This process involves dissolving the ore in molten cryolite and then passing an electric current through the solution, which separates the aluminum ions from the oxygen. During the process, the aluminum ions are reduced at the cathode, forming liquid aluminum, while oxygen is released at the anode. The liquid aluminum can then be collected and cast into various shapes. This method is efficient and has made aluminum production more accessible and cost-effective since its development in the late 19th century.
