It is possible to recover uranium from low grade ores ( to % uranium) and low grade nuclear wastes. In situ bioleaching technique is commonly used for extracting uranium. In the technique employed, the insoluble tetravalent uranium is oxidized (in the presence of hot H 2 SO 4 /Fe 3+ solution) to soluble hexavalent uranium sulfate.
