Abstract

This paper embodies the results of petrographical and mineralogical investigations carried on bauxite deposit of Darai-Daldali plateau, Kabirdham district, Chhattisgarh. Representative samples of bauxite, lateritic bauxite and laterite were studied to know petrographic and mineralogical variation. Microscopic examinations show pelitomorphous-collomorphous texture, due to colloidal precipitation. The XRD data reveal abundance of gibbsite in bauxite samples, followed by anatase, brookite and kaolinite, while lateritic bauxite and laterite samples are enriched in goethite, hematite and anatase in addition to gibbsite. Results of DTA/ TG and FTIR analysis confirmed the absence of boehmite. Minor variation in DTA/TG peaks most probably accounts for the variation in sample quantity taken for analysis.
