Physical Bauxite Processing: Crushing and Grinding of Bauxite
To process the bauxite, the bauxite must be mined, crushed, and delivered to the refinery. The first step to reaching the refinery after mining the bauxite is crushing. The Milling of the crushed bauxite product (Table 2) takes place in caustic spent liquor at temperatures of ~ 75 °C and delivers a slurry for desilication and digestion.
