Pilot Plant - Jamaica Bauxite Institute

2021-11-14  The production of alumina from bauxite is carried out by the use of the Bayer Process. 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 ...
