Initially, the bauxite ores are obtained and then crushed mechanically. The crushed ore is then mixed with caustic soda and put into a grinding mill, then made into a slurry containing the ore. The slurry is then pumped into the digester. The digester is a large tank that acts like a pressure cooker. The slurry is heated to 110-270°C at a ...

Bauxite deposits form close to the surface. Hence, all the mines in the world are open pit. About 8-14 tons of bauxite is needed to produce one ton of aluminum 1. So the ore of aluminum needs to be fairly rich in this metal to be worth mining. Aluminum is extracted solely from bauxite, but that does not mean that there are no alternatives.

The bauxite ore contains aluminum trihydrate (Al (OH) 3 ). Alumina refining produces alumina (Al 2 O 3) from the bauxite ore, by exploiting the reversible reaction of the Bayer process 1–3 : The reaction is firstly driven in the sodium aluminate (NaAlO 2) direction by the addition of caustic soda (NaOH) to bauxite.
