“…In the current process, the utilization rate of rare earth resources is low level, and most of the rare earth resources are discharged into the tailings [16]. With the continuous mining, the mineral composition, mineral process properties and element distribution of the ores has changed obviously [17]. MPIM and MPIE can provide reference for the establishment of geometallurgical matrix and database.…”

Rare earth resources are of great economic and strategic importance. The Bayan Obo, as the largest Nb-Fe-REE deposit in the world, have attracted much attention in mining field. This paper provides two index parameters of ore that can be used to quickly distinguish the ore types with exploitation value or industrial significance, which is helpful for geometallurgy and remote sensing prospecting. Seven ore types from the main and eastern orebodies of Bayan Obo deposits were collected for this study. The composition of mineral and element of each sample was acquired by TESCAN Integrated Mineral Analyzer (TIMA). Method of principal component analysis (PCA) was employed to analyze the compositional data. Metallogenic potential index of minerals and elements (MPIM and MPIE) were defined to make quantitative appraisal on the resource potentiality of Bayan Obo deposit. The ore types with a higher index are thought to be rich in REE. The results show that MPIM and MPIE are helpful to judge the metallogenic potential and mineral exploration in Bayan Obo deposit. The research is expected to be applied to the fields of geometallurgy and remote sensing exploration.
