How aluminium made in industrial smelting and refining plants?
Industrial aluminum production relies on the 1888-patented Hall-Héroult process, consuming approximately 13,500 kWh per metric ton. Refineries process bauxite ore—containing 30-50% alumina—using the Bayer method at 150-200°C under 5 atmospheres of pressure. It requires four tons of bauxite to produce two tons of alumina, which yields one ton of 99.7% pure aluminum via electrolysis. Smelters […]
