There are five principal species within the kaolin (sometimes called kandite) group: kaolinite, dickite, nacrite, halloysite, and metahalloysite. Minerals in the kaolin group are characterized by a 1:1 tetrahedral : octahedral structure. These are dioctahedral minerals. Pectin is a polyuronic polymer.

Kaolinite was treated three times, for 6 h each, with 8 M HCl or 5 M KOH. The adsorbents were characterized by XRD, FTIR, EDS, and BETN2. The effects of contact time and dye concentration on adsorption capacity and kinetics, electronic transition of bixin before and after adsorption, and also mechanism of bixinkaolinite adsorption were investigated.

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium. Bauxite consists mostly of the aluminium minerals gibbsite, boehmite and diaspore, mixed with the two iron oxides goethite and haematite, the aluminium clay mineral kaolinite and small amounts of anatase and ilmenite. In 1821 the French geologist Pierre Berthier discovered bauxite near the .
