List of Regions in Indonesia Producing Bauxite, a Natural Resource That Can Make You Rich

- Electrical – transmission cables, electrical components.

- Consumer – cookware, electronics, food and beverage packaging.

- Energy – turbine components, solar panels, and new energy infrastructure.

So when someone asks, "What is bauxite used for?", the answer is: bauxite is the gateway to almost the entire modern aluminum ecosystem.

Geological Processes: How Is Bauxite Formed?

Bauxite doesn't just appear out of nowhere. It forms through a long process called lateritization.

This process takes millions of years in tropical climates with high rainfall and relatively warm temperatures year-round.

Bauxite Formation Stages

- Weathering of Parent Rock

Granite rocks rich in feldspar and mica minerals undergo chemical weathering due to rainwater and high temperatures.

- Leaching of Soluble Elements

Elements such as sodium, potassium, calcium, and magnesium dissolve and are carried away by water, leaving behind the more resistant aluminum and iron.

- Aluminum Enrichment

Over time, the soil layers become increasingly rich in aluminum, forming red to brown laterite soils.

- Bauxite Mineral Crystallization
