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.

Bauxite & Aluminum - Jamaica Bauxite Institute

The gibbsite content of Jamaican bauxite ranges from 34-46%, whereas boehmite can range from 1-12%. For this reason, Jamaican bauxite may be classified as `mixed' trihydrate/monohydrate or gibbsite/boehmite bauxite. Some amount of blending can be tolerated in the processing, and this is encouraged in order to maximize use of the resource.
