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. ANTAM Bauxite commodity is produced in Tayan Bauxite Mining, West Kalimantan, its operated by West Kalimantan Bauxite Mining Business Unit.
The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.
Bauxite mining emits, on average, less than 100 kg CO 2 per tonne of bauxite. Mine operators have adopted a number of strategies to use energy more efficiently and to reduce emissions. These strategies include: Purchase of larger, more energy efficient mining equipment and trucks; Improved maintenance of mining and transport machinery;
