摘要
Abstract
A sandstone-type uranium deposit in Xinjiang belongs to auspicious prospecting stage with exploration line of 200 m×200 m,low exploration degree,thin ore bed and low uranium content.In addition,there are complex hydrogeological conditions with poor permeability(permeability coeffi-cient is only 0.045 m/d)and high pressure head.No leaching test work has been carried out in this deposit area.In order to study the leaching of uranium resources in the deposit,field leaching test was carried out by adopting neutral leaching and improving the pressure leaching technology,the results show that the average extraction volume of single hole is 1.7 m3/h,the average mass concentration of uranium in leaching solution is 40.37 mg/L,the maximum mass concentration of uranium in single hole is 390.22 mg/L,and the annual leaching recovery is 13.39％,it provides technical support for the exploitation of uranium resources in the deposit.关键词
