摘要
Abstract
Due to the change in ore properties of a certain hard rock uranium mine with the increase of mining depth,the heap leaching process of the ore encountered the problem of heap scaling.In order to solve the problem,the effects of leaching agent acidity,spray intensity,column height and particle size on heap scaling were studied.The results show that when the acidity of the leaching agent is 50.0 g/L,the spray intensity is 40.0 L/(m2·h),and the leaching period is 30 days,there is no scal-ing in the column leaching test,and the uranium leaching rate of-10 mm ore reaches 83.40％.The results of the 800 t ore pilot test confirms that there is no scaling in the heap with high acidity and large spray intensity,and the uranium leaching rate reaches 86.57％.关键词
