Bauxite is named after the town of Les Baux-en-Provence in France, which is where the geologist Pierre Berthier first identified the mineral in 1821. Aluminium is the third most abundant metal found in the Earth's crust but it is never found free in nature. It has always reacted with other elements to form compounds such as aluminium oxides.

 · The first step of the Bayer process is to use the crushing equipment to crush the bauxite ore into particles with a diameter of about 30 mm. As the particle size becomes smaller, the specific surface area of the bauxite greatly increases, which helps to speed up the follow-up speed of the chemical reaction. Step 2- Washing and separating processes

 · Number of Bauxite resource nodes is as follows: * Note: The extraction rate of a Miner Mk.3 at 250 % is 1,200/min, but a Mk.5 Conveyor can only carry 780/min, therefore the maximum mined amount cannot be transported. Extraction energy It takes about 11.17 MJ to extract 1 Bauxite. Further reading: Extraction energy Usage Crafting AWESOME Sink
