The process was invented in 1888 by an Austrian, Karl Joseph Bayer. Bayer discovered that when bauxite was mixed with caustic soda, the alumina content in the bauxite would dissolve and separate itself from the other components, such as iron and silica, which would remain in solid state.


The Bayer process is a chemical process widely used in industry to produce alumina from bauxite. Invented by Austrian engineer Karl Joseph Bayer in 1887, the basic principle is to convert aluminum hydroxide into sodium aluminate with concentrated sodium hydroxide solution, and to re-precipitate aluminum hydroxide by diluting and adding aluminum hydroxide seed crystals.
