The main objective of this work is to upgrade lean ore of Bauxite. Upgradation of low grade ore by bioleaching process with microorganisms is a new area and offers economic benefits in commercial production. The present work includes studying the indigenous bacteria isolated from the ore which have capable to leach out Aluminum from the same ore sample. The work also has aim to characterize the indigenous microorganism responsible for removal and also to find out the optimum condition for the process.
