| Summary: | Rare earth elements are widely used in permanent magnet, metallurgy, hydrogen storage materials and other fields due to their special properties, and their consumption is increasing year by year. China is a big country with rare earth element reserves. By 2020, China's rare earth element mineral production in the world accounted for a decline year by year, and has rebounded in recent years, but it is necessary to find and develop other materials that can be used as a supply source of rare earth elements. Coal, as a kind of organic mineral, can enrich rare earth elements during its formation. Deeply recognizing the content and occurrence state of rare earth elements in coal is of great significance for the subsequent research on the occurrence, extraction and recovery of rare earth elements in combustion products. Scholars at home and abroad studied the content of rare earth elements in coal by era, region and coal grade, and the research on the occurrence state of rare earth elements in coal and its combustio |
