[Location Factors] Aluminium-Bauxite Refining,

First, Bauxite ore is crushed, washed and mixed with caustic soda to remove impurities. Then it is dried in large furnaces to remove moisture content=> you get alumina. During this phase, ~50% or more weight loss happens. Hence, this process (of converting bauxite to Alumina) is done near the raw material side.
