摘　　要：简要叙述了溶浸采矿的重要意义,并主要以GX铀矿样为例进行碎裂蚀变花岗岩型铀矿溶浸试验。介绍了中南地区碎裂蚀变花岗岩型铀矿样的矿物组成及性质、铀含量、化学组分、原矿筛析、柱浸和富集过程,以及溶浸采矿的直接成本核算方法与核算结果。该试验结果为本区溶浸采矿的半工业试验提供了基础数据。The paper briefly describes important significance for solvent leaching mining; and solvent leaching test on cataclastic altered granite type uranium ore is conducted with ore samples from GX uranium deposit,and made an introduction on constituents,properties of the minerals,uranium content,chemical components of ore sample,the process of analysis,screening,column leaching and concentration of raw ores,and finally discusses the method and result of the direct cost calculation of solvent leaching mining. The tested results lay a foundation for the pilot industry test of solvent uranium leaching in central south China.
