Thus silica is a key determinant of any bauxite’s economic value. Important impurities and their effects listed opposite. Some impurities, for example gallium, build up in the refinery liquor and are potentially an economic by-product. However due to a very small market for such metals very few refineries extract and sell them. Kaolinite

Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts. The principal aluminum hydroxide minerals found in varying proportions with bauxites are gibbsite and the
A process for removing silica from bauxite is disclosed. The method includes the step of mixing bauxite with a caustic liquor to form a mixture and to dissolve and stabilise at least a substantial part of the reactive silica from the bauxite. The caustic liquor is selected to have a high caustic concentration and a high alumina content.

Typically, a bauxite resource contains 30-60% alumina (Al 2 O 3), and occurs as two main types: trihydrate (“low temperature”) bauxite and monohydrate (“high temperature”) bauxite . The other main indicator of bauxite quality is the silica content, usually reactive silica for a low temperature bauxite or total silica for a high temperature bauxite
