The Bayer Process is a method used to extract aluminum from its ore, primarily bauxite. The process involves crushing the bauxite and mixing it with a hot, concentrated solution of sodium hydroxide. This solution dissolves the aluminum oxide in the bauxite, leaving behind impurities. After the aluminum oxide is dissolved, the solution is allowed to cool, and aluminum hydroxide precipitates out. This precipitate is then filtered, washed, and heated in a kiln to produce alumina, which can be further processed to obtain pure aluminum metal through the Hall-Héroult process.
