    2020-7-15 · In earlier posts we have discussed about various techniques for grinding of bauxite. The basic objective of grinding of bauxite is to increase the surface area of material substantially so as to improve its reactivity with caustic soda to a desired level during digestion process. As such wet grinding of bauxite has been found to be energy efficient and environment friendly as well.
