How Aluminum is Produced - Mineral
STEP 1 – Crushing and Grinding: Alumina recovery begins by passing the bauxite through screens to sort it by size. It is then crushed to produce relatively uniformly sized material. This materials is fed into a large grinding mill where it is mixed with a caustic soda solution (sodium hydroxide) under high temperature and pressure.
