Leaching characteristics of a low grade uranium ore
摘要
Abstract
Leaching characteristics of a low grade uranium ore in Jiangxi province are studied using agitating leaching and column leaching methods. The results of agitating leaching test show that leaching rate of uranium is above 85% under the conditions of sulphuric acid concentration of 10 g/L and stirring 12 h, and the ore is leachable. The results of column leaching test show that leaching rate of uranium is above 85. 7% under the conditions of particle size of -5 mm, sulphuric acid dosage of 4. 6% (w/w),and leaching time 40 d, and the permeability of ore heap is good(33 L/m2 h). The obtained leaching parameters can be used as the basis of industrial experiment design and adjusting the leaching parameters in production.关键词
