aluminum smelting technology

Aluminum smelting is the process of extracting aluminum metal from its ore, primarily bauxite. This is done through a method called electrolysis, where bauxite is turned into alumina (aluminum oxide) and then dissolved in molten cryolite. An electric current is passed through this mixture, causing aluminum to separate and settle at the bottom of a cell, while oxygen is released at the top. The aluminum is then collected, resulting in pure metal ready for use. This energy-intensive process is vital for producing aluminum, a lightweight and versatile material used in countless applications.
