  Physical Bauxite Processing: Crushing and Grinding of Bauxite

  2022123 · The first crushing of the bauxite may often take place at the mine before transport to the alumina refinery if located nearby, or to the shipping port for export. At the refinery further crushing and/or washing may take place before the crushed bauxite is subjected to a grinding operation for final sizing before digestion.
