Description

The leaching mechanisms of carbon dioxide, oxygen and carbonate are analyzed, and theoretical and experimental enhancements of in situ leaching carried out by state equation of U (VI) alkali solution and a simulation device. The results shows that (1) The leaching can be improved by increase of oxygen concentration; (2) The pH value of mining solutions can decreased by addition of carbon dioxide; (3) The leaching can be improved by increase of bicarbonate concentration for the lower uranium content ores.
