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.
