Water reclamation and effluent retreatment system at Jaduguda

Abstract

Neutralization of uranium mill tailing with lime provided in original flow sheet was not found adequate for effluent quality control within limits particularly as regards to{sup 226}Ra and Mn. The same was being controlled by dilution and hence no water was being reclaimed. In October 1987 the Jaduguda mill was expanded to augment its ore processing capacity from 1000 MT/day to 1340 MT/day. This necessitated extra water requirement, which could have been met only with water reclamation. But this would have resulted in build up of pollutant ions apart from less water available for dilution. Hence a composite scheme was made for water reclamation and treatment of effluent with BaCl{sub 2} to precipitate Ba(Ra)So{sub 4} and with lime to precipitate Mn as hydroxide. This effluent treatment plant was commissioned in May 1990 and is working satisfactorily. The scheme is being further modified and augmented to take care of Narwa mine water and sewage treatment plant effluent. (author).
