Abstract

PURPOSE: To recover uranium easily from a dilute uranium solution acidic with sulfuric acid and containing organic materials, by contacting the solution with a specific polymeric material and then with a uranium desorption agent, thereby selectively adsorbing uranium.
CONSTITUTION: A uranium-containing ore is leached with sulfuric acid, and the leachate is extracted with an amine extractant composed mainly of a tert-amine. The extraction residue, i.e. a dilute uranium solution acidic with sulfuric acid and containing one or more compounds selected from amines, alcohols and hydrocarbons, is brought into contact with a polymer containing a copolymer of vinylpyridines and divinylbenzenes as a main chain or side chain. The pH of the acidic dilute uranium solution is about 0.5W3.5, and the uranium concentration is about 0.1W30ppm. Then, the polymer is brought into contact with a uranium desorption agent such as aqueous solution of sulfuric acid. The agent is about 0.5W 10N concentration. The uranium is collected and recovered by this process.
