我国多数低品位铀矿床具有致密、坚硬、需先予以破碎而后才能应用浸出技术提取铀金属的特点。针对这些特点,进行了留矿法落矿的原地浸铀试验研究,对与此相关的采准系统、切割工艺、爆破参数、爆破工艺、喷淋系统、喷淋参数及集液系统等进行了试验。通过试验研究,获得了理想的工艺参数,提高了铀金属的回收率。 Most low-grade uranium deposits in our country are dense and hard, and must be crushed before they can be extracted by leaching technology. In view of these characteristics, the in-situ leaching of uranium from the ore-splitting method was carried out. The related acquisition and cutting systems, cutting technology, blasting parameters, blasting process, sprinkler system, sprinkler system and liquid collecting system were carried out The test. Through experimental research, the ideal process parameters were obtained and the recovery of uranium metal was improved.
