The Héroult process is an industrial method used to produce aluminum from its ore, bauxite. This process involves the electrolysis of aluminum oxide, which is dissolved in molten cryolite. When an electric current passes through the solution, aluminum ions are reduced to form pure aluminum metal at the cathode, while oxygen is released at the anode. Developed by Paul Héroult in the late 19th century, this process revolutionized aluminum production, making it more efficient and cost-effective. The Héroult process remains the primary method for aluminum extraction today, contributing significantly to the global aluminum industry.
