Abstract: Sangaredi is a mining town in the Boke region of the Republic of Guinea, where bauxite deposits have been confirmed.e Sangaredi bauxite deposit is located at 11°06'00''N and 13°46'00''W in the Eastern Boke region, covers an area of about 10 km 2 and was formed as a result of deep alteration of sedimentary and igneous rocks.e purpose of the study is a geological assessment of the bauxite potential of the Sangaredi deposit in the Boke region based on a study of the geological situation of the area, petrographic and geochemical characteristics of ore samples. Methods of research.Geological studies of the Sangaredi deposit were carried out using X-ray diffractometry (XRD) and inductively coupled plasma atomic emission spectrometry (ICP-AES) techniques.Results.Geological analyzes show that gibbsite and boehmite are the dominant minerals in all bauxites with average concentration (91.85% and 3.3%, respectively), while goethite is the main ferruginous mineral with average concentration (1.35%) and hematite averages (0.7%).Diaspore elements, dawsonite, rutile and anatase are found in low abundance (< 1%).Analyzes of bauxite samples show significant differences in the content of Al 2 O 3 (56%-70.92%),Fe 2 O 3 (1.47-8.92%),SiO 2 (0.40-5.50%) and TiO 2 (2.60-5.72%),which are independent of their parent rocks.e Sangaredi bauxites have a very similar chemical composition, high in aluminum but low in silicon and iron, distinguishing them from other deposits in Guinea and many other parts of the world.
