dc.description.abstractSangarédi is one of the few areas in the Republic of Guinea with confirmed bauxite deposits. Sangarédi deposit, which was formed by deep weathering of sedimentary and igneous rocks, is located at 11°5'23'' N and 13°46'46'' W in the eastern Bokéregion where it crops out over an area of about 10 km2In this study, mineralogical and geochemical studies of the Sangarédi deposit were done by using X-ray diffractometry (XRD) and Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) methods. 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 an average of 0.7%. Diaspore, dawsonite, rutile, and anatase occur in low abundances (< 1%). Geochemical analyses of the bauxite samples show some significant differences in Al2O3 (55.63-68.92%), Fe2O3 (1.44-8.89%), SiO2 (0.47-5.68%), and TiO2 (2.48-5.45%). Regardless of their parental rocks, the Sangarédi bauxites have very similar chemical compositions, with high aluminum, but low silica and iron contents, which distinguish them from other deposits in Guinea and many other parts of the world.en_US
