La extracción del aluminio

The video explains the extraction of aluminum from its mineral form. Aluminum is highly reactive, making its extraction challenging. Bauxite, a naturally occurring aluminum mineral, is processed to remove impurities and obtain alumina. The Bayer process is used for this purpose. Electrolysis is then employed to separate aluminum from oxygen in alumina, requiring significant heat and electricity. The process involves electrolytic cells where aluminum ions are attracted to the cathode and oxide ions to the anode, resulting in pure aluminum after final purification. This method is used to produce millions of tonnes of aluminum annually.
