METHOD OF EXTRACTION URANIUM FROM ORE MATERIALS

摘要

chemical industry. SUBSTANCE: method comprises extraction of uranium by heap or underground leaching. Method comprises treatment of ore material with sulfuric acid solution. Ammonium alkali or alkali-earth metal are further added to sulfuric acid solution. Lignosulfonate concentration in leaching solution varies from 0.05 to 5.0 g/l. Method makes it possible to reduce leaching process time, lower consumption of acid and decrease volume of production solutions. EFFECT: more efficient extraction method. 2 cl, 2 dwg
