我省寻乌矿为一个火山岩风化壳离子吸附型稀土矿,这是一种新型的稀土资源。它储藏量大,是我省重要的稀土资源之一。就稀土各元素的配分情况来看,高镧低铈,富含镧钕,同时钐、铕、铽、钇的含量也较高,特别是钐铕在目前世界已知稀土矿中含量最高。该矿用P—204萃取分离的方法,将混合稀土分离成氧化镧铈富集物、氧化镨钕富集物、中稀土氧化物和重稀土氧氧物等四种成品。在氧化镧铈富集物的成品分析,不但要求分析稀土总量,更重要的是要求分析La、Ce含量。限于矿区的设备条件等原因,目前无法开展这方面的分 Xunwu mine in our province is a volcanic weathering crust ion adsorption type rare earth mine, which is a new type of rare earth resources. Its large reserves, is one of the important rare earth resources in our province. Lanthanum low cerium, lanthanum neodymium rich, while samarium, europium, terbium, yttrium content is also higher, in particular the samarium europium is currently the world’s highest content of rare earth mines. The mine with P-204 extraction separation method, the mixed rare earth separation into cerium oxide oxide enrichment, neodymium oxide enrichment, the rare earth oxide and heavy rare earth oxide and other four products. Finished product analysis of lanthanum cerium enrichment not only requires analysis of the total amount of rare earths, but more importantly requires the analysis of La and Ce contents. Limited to the conditions of mining equipment and other reasons, at this stage can not be carried out
