The Bayer Process, a thermo-chemical digestion method invented in 1887 by Austrian scientist Karl Josef Bayer, is the most economic means of obtaining alumina from bauxite. Ore is delivered to the refinery from the mine. The bauxite is washed and crushed to increase its surface area. Undissolved solids are removed from the pregnant liquor as bauxite residue . NaOH is recycled to the digestion process.
