Aluminum vs. Bauxite

Extraction. Aluminum is extracted from bauxite through a two-step process: refining and smelting. The refining process involves the extraction of alumina (aluminum oxide) from bauxite using the Bayer process. This process involves crushing the bauxite ore, mixing it with a hot caustic soda solution, and filtering out impurities to obtain a ...
