摘要
随着经济快速发展对能源需求的增加,当前我国南方硬岩型铀矿床开采量已经大不如前,砂岩型铀矿已成为天然铀供给的主力。砂岩型铀矿开采方式主要为原地浸出,按照溶浸剂的不同可以将其划分为酸法浸出、碱法浸出、中性浸出以及生物浸出等不同工艺。阐述了砂岩型铀矿的特点、总结了各种浸出方式的优点及应用条件、对浸出机理做了简要介绍,并对砂岩型铀矿开采的发展提出了展望。
With the rapid economic development of energy demand,current exploitation of hard-rock type uranium deposits in south China greatly drops,and sandstone type uranium deposits become a main supply.The main extraction method of sandstone type uranium ore is in-situ leaching,which can be divided into acid leaching,alkali leaching,neutral leaching,and biological leaching according to leaching agents.Characteristics of sandstone type uranium ores are described,advantages and application conditions of various leaching methods are summarized,leaching mechanism is briefly overviewed,and development prospect of sandstone type uranium ore mining is put forward.
