The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today. About 90% of alumina refineries in the world use the Bayer process. It's very efficient but it can only be used on high quality bauxite with fairly low content of admixtures, especially silicon.
