Mode of Occurrence and Distribution of Critical Metal Lithium and Other Trace Elements during Coal Preparation from Jiashun High-Sulfur Coal in Guizhou Province, China

During the Late Permian period, coal from Jiashun Mine in Xingren City, Guizhou Province, China, is characterized by a high sulfur (5.84%) and lithium (Li) (94.5 μg/g) content. Lithium critical metal context of global energy transition. Considering importance environmental protection resource utilization, mode occurrence distribution trace elements different preparation products were investigated. The obtained results indicated following: (1) minerals mainly composed veined epigenetic pyrite, quartz, kaolinite. Most could be effectively removed cleaned through gravity separation. (2) rare earth yttrium (REY) was relatively complex, they found middlings separation flotation tailings. (3) significantly influenced their removal rate. rate higher for compared to those using flotation. fine-grained wrapped organic matter or combined with portions had better that occurred both matters low rates (<25%) two methods. (4) Li more enriched (98 tailings (102 μg/g), reaching marginal grade (80 coal. (5) may derived intermediate-felsic rocks at top Kangdian Upland late hydrothermal solutions.
