由于通货膨胀,矿石中铀品位的降低和必须开采新型矿石(10％以上是已探明但还未算进要开采的铀资源中,要求用新方法处理)引起的基建费和生产费用的提高,以及对排放至尾矿坝尾矿中的放射性核素和化学物质浓度的严格要求,都刺激了旨在改进工艺过程及其设备装备的科研和实验设计工作。本文分析了已进行的研究工作。第一部分——水冶工序前的矿石准备工作、浸出、固液分离;第二部分——从清液和矿浆中提取铀和矿石加工厂废物的处理;第三部分—综合利用铀原料、从磷酸盐中副产回收铀、地下浸出和堆浸。
Increases in capital costs and production costs due to inflation, lower uranium grade in ores, and the need to extract new types of ore (over 10% of uranium resources that have been identified but not yet accounted for) , As well as the stringent requirements for the concentration of radionuclides and chemical substances that are discharged into tailing dam tailings stimulate research and experimental design efforts aimed at improving processes and their equipment and equipment. This article analyzes the work that has been done. Part I - Ore preparation, leaching, solid-liquid separation prior to the hydrometallurgical process; Part II - Treatment of uranium and ore processing plant wastes from the extraction of clear liquid and pulp; Part III - Comprehensive utilization of uranium feedstock from Phosphate by-product recovery uranium, underground leaching and heap leaching.
