Treatment of radioactively contaminated waters with an increased content of salts

The article gives a comparison characteristic of purifying highly mineralized radioactively contaminated mine waters by different methods. It is shown that the use of the coagulation method does not ensure purification to the MAC standards, while the sorption-coagulation method requires additional conditioning of spent sludge. For complex purification of mine waters (of the uranium compounds and partially of hardness salts) the reagent-magnetic method was proposed with the use of iron(II) and (III) salts, alkaline reagent CaO and natural magnetite.
