Geochemical and Mineralogical Characteristics of the Li-Sr-Enriched Coal in the Wenjiaba Mine, Guizhou, SW China.

This paper reports the mineralogical and geochemical compositions of C6 coal in the Late Permian Longtan Formation of the Wenjiaba Mine, Northern Guizhou in southwest (SW) China. The geochemical and mineralogical studies are the basis for the potential recovery of critical metals. The Longtan Formation, which is one of the major coal-bearing strata in SW China, contains dozens of coal seams.

Enrichment and Occurrence of Mn in 5 Coal from Qinglongsi Coal Mine, Northern Ordos Basin, China.

High concentrations of Mn were observed in 5 coal (Jurassic age) from Qinglongsi coal mine in the Northern Ordos Basin. To study the occurrence characteristics and sedimentary environment of the 5 coal (3.9 m), 22 samples were collected from a mining face.
