Bauxite Types and Uses - Australian Bauxite Limited

Bauxite is aluminium-rich ore that is used for aluminium production (the metallurgical bauxites) and for production of refractory materials, chemicals or cements (the non-metallurgical bauxites). Metallurgical bauxites are sub-divided into two basic types based on the processing methods that must be applied to them at the alumina refinery stage ...

Bauxite - Sandatlas

Bauxite is a result of intense leaching in a hot and humid climate with alternating wet and dry seasons and good downward drainage. The climate promotes vegetation that provides organic acids, which help to dissolve rocks in percolating water that carries more soluble components away, leaving only aluminum and also often iron as the least mobile common ions behind.
