The electrochemical extraction of aluminum from bauxite ore involves (A) the reaction of Al₂O3 with coke (C) at a temperature > 2500 °C. (B) the neutralization of aluminate solution by passing CO₂ gas to precipitate hydrated alumina (Al₂O3-3H₂O). (C) the dissolution of Al2O3 in hot aqueous NaOH. (D) the electrolysis of Al2O3 mixed with Na3AlF6 to give Al and CO2.
