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 investigat...

This paper investigates the efficiency of fuel enrichment to reduce costs thermal power plants (TPPs). An objective function is formulated define and measure desired results. The annual TPPs additional associated with use highly abrasive coal are analyzed. enrichment, in particular, flotation considered. A cost analysis a transportation problem presented demonstrate In general, this provides in...

Graphite ore collected from Hunan province, south China was characterized by chemical analysis, X-ray diffraction, and optical microscopy. Rougher and multi-stage flotation tests using a mechanical flotation cell and a flotation column containing an additional centrifugal force field were carried out to promote its grade and economic value. In rougher flotation, both the mechanical flotation ce...

The influence of conditioning on the flotation of pyrrhotite in the presence of chlorite was investigated through flotation tests, sedimentation tests, and X-ray photoelectron spectroscopy (XPS) analysis. The flotation results show that chlorite slimes dramatically impair the flotation of pyrrhotite. Sedimentation and flotation tests reveal that conditioning can effectively remove chlorite slim...
