Map of the Largest Bauxite Producing Regions in Indonesia
Nationally, Indonesia's bauxite reserves are concentrated in several key regions. However, in terms of production scale, infrastructure, and deposit quality, there are four major clusters:
- West Kalimantan: the largest and most productive bauxite producer.
- Riau Islands (especially Bintan Island and its surroundings): high-quality bauxite and close to international shipping routes.
- Central Kalimantan: Huge potential that continues to grow.
- Bangka Belitung: Better known for tin, but also has bauxite in several areas.
Beyond that, several regions in Sumatra, Sulawesi, and Papua also have indications and bauxite reserves, although not as large as the four main clusters.
