2020-4-7 What Is the Bayer Process? The Bayer process is a chemical process widely used in the industry to produce alumina from bauxite. Invented by Austrian engineer Karl Joseph Bayer in 1887, the basic principle is to convert aluminum hydroxide to sodium aluminate with concentrated sodium hydroxide solution, and to re-precipitate aluminum hydroxide by diluting and adding aluminum hydroxide seeds.
