Abstract
The most common process step to feed an alumina refinery with bauxite is sizing of the raw bauxite material that is extracted from the mine. 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. This chapter present some of the various crushing, washing, and grinding equipment available in the market as well as the various options for designing a grinding flowsheet.
