Physical Bauxite Processing: Crushing and Grinding of Bauxite
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 …

Bayer process
Bayer process The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. [1]
