washing, wet screening and cycloning, or even by hand picking and sorting. The bauxite is sometimes dried before shipping. 4. Bauxite is converted to alumina (aluminium trioxide) through the Bayer process. In this process, concentrated caustic soda is used to extract alumina from bauxite at elevated temperatures and pressures.
PT ANTAM Tbk | Bauxite
Bauxite, the raw material for the production of alumina, was first discovered in 1924 at Kijang, Bintan Island, in the province of Riau, in northwestern Indonesia. Bauxite from Bintan Island has been mined and exported since 1935. In 1968 ANTAM acquired the mine. Thus, ANTAM is Indonesia's longest running producer of bauxite.
