Purification of water from uranium and sulfates during liming in the presence of aluminum coagulants
The conditions for the effective purification of mine waters from sulfates and uranium compounds during their softening have been determined. It has been established that the use of aluminum coagulants and lime in quantities sufficient to bind sulfates into calcium sulfohydroxoaluminate provides a decrease in the content of sulfates to 200 - 400 mg/dm<sup>3</sup> while reducing the uranium content to concentrations lower than the maximum permissible in surface water bodies.
