SUSTAINABILITY IN ALUMINA PRODUCTION FROM BAUXITE
BAYER PROCESS Alumina is mainly produced from bauxite ore through the well-known Bayer process, a hydrometallurgical process invented by Carl Josef Bayer in 1888-1892. 1 A simplified process flowsheet for the process is illustrated in Figure 2. In this process bauxite ore is digested with lime addition by a solution of caustic soda (NaOH).
