Abstract
Mining of low grade uranium ore commenced at Jaduguda in eastern India in the mid 1960s. Presently, the uranium ore from four underground mines located within a distance of 22 km is processed by the Uranium Corporation of India Ltd. (UCIL). A few more mines are envisaged to meet the nuclear fuel requirements. Management of mine water, mill tailings and the effluents from the tailings containment facility is given due importance. Liquid effluents are treated with BaCl2 and lime slurry to remove 226Ra, Mn and other pollutants. A large portion of the treated effluents is re-used, the rest being disposed to the aquatic system after ensuring that they meet the regulatory standards of discharge. Surface and ground water monitoring results are presented in the paper.
