摘　　要：结合某铀矿床碱法地浸室内试验，进行了氧化剂的种类、质量分数和溶浸剂的种类、质量分数选择试验，研究了反应时间、矿石粒度对铀浸出率的影响。结果表明，碳酸（碳酸氢）钠盐或铵盐是良好的溶浸剂，铀浸出率可达到70％～80％；加入质量分数为0．1％的双氧水和质量分数为0.02％的高锰酸钾，铀浸出率明显提高，可满足铀浸出需求。According to the in-room experiment for alkaline leaching of uranium deposit, the effects of the sorts and concentration of oxidants and solvent solutions are studied. The relation of reaction time and uranium ores granularity to leaching results are discussed. The results show that the 70 % - 80 % leaching efficiency was attained by bicarbonate and carbonate （sodium or ammonium） leaching with 0.1% hydrogen peroxide or 0.2 % potassium permanganate and which it can meet the demand of uranium lixiviation.
