| 摘 要： | 以稀土磷块岩矿床为研究对象,采用电感耦合等离子体光谱法和质谱法研究了3个代表性样品的基本化学组成,分析了40多个元素的含量,确定了矿物质量分数和赋存状态,研究了稀土元素在其中的分布特征。结果表明,97%以上的稀土元素呈类质同象状态部分置换磷灰石晶格中的Ca2 存在,只有小于3%的稀土元素呈被粘土质等吸附状态或离子交换(吸附)状态存在。 |

| Abstract: | This paper studies the deposit of rare earth phosphorite.Three typical samples were collected and the basic chemical compositions of the samples were studied using ICP-AES and ICP-MS.The test results of forty elements were analyzed,the amount of minerals and their occurrence were determined and the distribution characteristic of rare earth was studied.The results show that the measurement of the same element from various minerals matches the element's individual measurement.Ninety-seven percent of REE is hosted as isomorphic impurities replacing Ca2 in apatite crystal lattice.Only three percent of REE is hosted in clay absorbed state or ion-exchange(absorbed) state. |
