原地破碎浸出法开采低品位铀矿体的应用与实践

STUDY AND PRACTICE OF IN-PLACE LEACHING OF LOW GRADE URANIUM ORE BODY

本文详细地介绍了用原地破碎浸出采矿法试验性开采某铀矿体的方法 ,具体地阐述了原地破碎浸出采矿法的矿体选择、落矿筑堆工艺、布液浸出工艺等内容。该方法取得的成功 ,为采用常规采矿法的铀矿山回收更多的低品位铀矿金属提供了成功方法 ,为大力发展原地破碎浸出溶浸采矿法提供了成功经验。

This paper deals with a trial inplace leaching system which was used to mine the low grade uranium ore body.A detailed description is given on the selection criterium for the ore body to be exploited by the system,the heap construction technology and the system of leachant spraying and pregnant solution collection.The trial provides a successful example and effective means for recovering low grade uranium ore resources.
