Studies on mother liquor of heap and sunken uranium leaching electrochemical treatment

Abstract

The work is dedicated to reactivation of mother liquor of heap and sunken uranium leaching. A new method offers reactivation without using oxidizing additives. Electrochemical treatment presumes direct oxidation of Fe2+ ions, which the mother liquor contains. An advantage of the electrochemical method is that it's less expensive than using additives and much easier to use in cross-country conditions. The cost-efficiency of electrochemical treatment versus polianite additive method was shown.
