摘　　要：混合岩离子型稀土矿床在赣南分布广泛,其结构构造及稀土配分与花岗岩存在差异性。就浸取效果对赣南某混合岩型离子型稀土矿的浸取浓度做了柱浸试验,并且对不同浓度浸矿剂所需的浸矿时间及所浸出的母液浓度等浸取效果进行对比分析,以期给该矿山的稀土回收提供技术参考。Migmatite of ionic type rare-earth ore deposits are widely distributed in south of Jiangxi Province,whose construction and partition are different from that of granite. Column leaching tests were conducted on the leaching concentration of the migmatite of ionic type rare-earth ore deposits in Gannan for the leaching effects,and contrastive analysis were made between different leaching effects such as different requirements in time and concentration of the rare earth lixivium due to imparities in concentrations of leaching lixiviants,thus providing technical reference for the recovery of rare earth in this mine.
