江西大布铀矿床溶浸地质条件及溶浸方法研究

围绕溶浸采矿这个主题 ,从岩、矿石的物质成分 ,矿石结构构造 ,铀的存在形式 ,岩、矿石物理力学参数 ,矿体形态、产状、规模及矿床水文地质等诸多方面阐述了大布铀矿床溶浸的天然地质条件 ,并通过一系列矿石铀浸出工艺试验 ,获得大量溶浸工艺参数 ,提出大布铀矿床以原地破碎浸出辅以堆浸为最佳采矿方案。

STUDY OF LEACHING GEOLOGICAL CONDITIONS AND SOLUTION LEACHINGMETHOD OF THE DABU URANIUM DEPOSIT IN JIANGXI

Round the theme of solution leaching mining, this paper expounds the natural geological conditions of the Dabu uranium deposit on the following hands: the compositions of rock and ore, the ore texture and structure , the uranium element existing form, the physical and mechmical parameters of rock and ore, the shape, attitude and size of orebody, and also the deposit hydrogeological conditions. At the same time, a lot of parameters of technological test are gained through a series of ore uranium extracting tests. At last, the best mining scheme adopting crashed in situ leaching assisted by heap leaching in the Dabu uranium deposit mining is suggested.
