Abstract
The present study demonstrates the possibility of development of efficient leaching processes for the extraction of uranium from a low-grade ore and for the removal of long half-life radionuclides, especially radium-226, from the leach residues in order to produce environmentally safe and radiochemically innocuous tailings. The report provides kinetic information, not previously available, for low-grade uranium ore leaching by sulfuric and hydrochloric acids and by sodium carbonate and bicarbonate leachants. Based upon a statistical experimental design, a generalized mathematical form was developed for the initial rate of uranium extraction as a function of the leaching parameters using a linear regression computation technique. A specific ion exchanger for the removal of radium-226 from leach solutions and actual neutralized tailings effluents was developed. This solid ion exchanger can be obtained through a simple treatment of commercially available organic resins.
