摘要：

Based on the detailed field investigation and a large number of field samples, the distribution regularity of rare earth in dolomite type of main ore and east ore in Bayan Obo was systematically studied, via the multi element analysis, SEM-EDS and the automatic mineral analysis system, some differences in the grade and the distribution of the rare earth between bastnaesite and monazite were found. The REO content of bastnaesite is generally higher than that of monazite, and it is easier for bastnaesite to capture more La and Ce, monazite has stronger binding ability to medium heavy rare earth elements. There is no obvious enrichment tendency of Pr and Nd between the two minerals.we put forward the suggestion of fine production. The best mineral raw materials of La, Ce, Pr and Nd is the main (east) ore bastnaesite, main (east) ore bastnaesite, main ore monazite and east ore bastnaesite respectively. This study has certain guidance and reference significance for further understanding of the main types of rare earth ores in the deposit and exploration of fine and efficient utilization of rare earth resources. © 2021, Editorial Office of Journal of the Chinese Society of Rare Earths.
