摘　　要：南方某铀矿床的矿石为高含泥量碎裂花岗岩型矿石,采用常规的堆浸技术,存在渗透性差、浸出率低、浸出周期长等一系列问题.为此,本次研究通过进行搅拌浸出试验,探求合理的工艺技术参数.试验研究取得了满意的结果,通过对高含泥量碎裂花岗岩型铀矿石开展搅拌浸出试验,获得了合理的技术参数和优化条件,铀浸出率可达95%以上,为今后开展现场扩大试验打下了基础,并对该类型的铀矿石缩短浸出时间,提高铀浸出率,最大限度的提高铀资源回收率和经济效益有重要研究意义.The ore of a uranium deposit in the south of China is a high-content-type ore,with a series of problems,such as low permeability,low leaching rate and long leaching period.This study through the agitation leaching test,explores reasonable technical parameters.It achieved satisfactory results.Through carrying out agitation leaching to high mud weight cataclastic granite type uranium ore,reasonable technology parameters and the optimized conditions were obtained,uranium leaching rate reached 95% above,which laid the foundation for the future field enlarged experiment and is significant for shortening the leaching time,improving the leaching rate,recovery rate and economic benefit.
