It could be seen that the product toxicity by spontaneous combustion of coal and gangue mainly depends on the components of PAHs components and their toxic equivalents. 5. Conclusions (1)

In mining, gangue (/ ɡ æ ŋ /) is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings, which is ...

After drying, the gangue disintegrates into its component small particles but the kerogen pellets dry to a hard brittle mass exhibiting no evidence of the presence of discrete small particles.

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.

Chemical composition of coal gangue was determined, and its performance as a water treatment material was tested. Results showed SiO 2 was the dominant chemical component of coal gangue.
