Bauxite Grinding Mill: Unveiling the Role in Aluminum Production
The primary function of bauxite grinding mills is to pulverize bauxite ore into a finely ground powder. This powder, also known as bauxite dust or red mud, is subjected to the Bayer process, a chemical refining method that extracts alumina from bauxite. The ground bauxite's high surface area facilitates efficient leaching of alumina in the ...
