The Hall Process is an industrial method used to produce aluminum. It involves the electrolysis of aluminum oxide, or bauxite, dissolved in molten cryolite. This process separates aluminum metal from oxygen, allowing for the extraction of pure aluminum. Developed by Charles Martin Hall in 1886, the Hall Process revolutionized aluminum production, making it more efficient and cost-effective. Today, it remains the primary method for producing aluminum worldwide, contributing significantly to various industries, including construction, transportation, and packaging.
