Dec 20, 2020 The mineralogical analyses show that gibbsite and boehmite are the dominant minerals in all of the bauxites, with average concentrations of 91.85 and 3.3, respectively. Goethite is the major iron mineral, with an average concentration of 1.35. whereas hematite makes up average of 0.7.
Mixtures of gibbsite and boehmite are common in all types of bauxites, boehmite and diaspore less common, and gibbsite and diaspore rare. Each type of bauxite ore presents its own challenges in terms of mineral processing and beneficiation for the generation of alumina 7,8. Table 1. Chemical composition of Gibbsite, Boehmite and Diaspore 3.
The fine-grained and tabular form of gibbsite make it most likely to be confused with other clay minerals, like kaolinite. Bauxites are the principal ore of aluminum and typically contain high quantities of one or more of these Al hydroxides. Bauxite deposits occur in many areas of the tropics and subtropics zones.

Bauxite primarily comprises minerals such as boehmite, gibbsite, hematite, goethite, ilmenite, and anatase. It is usually found near the surface of the terrain hence, strip mining, a type of surface mining, is carried out.
