jiggingtechnologyprocessimprovementcoalwashing

Jigging is an ancient but mature coal washing technology by gravity. It has more than 110 years history since the application of air jigging machine. However, because the theoretical research of jigging coal washing technology is still wandering at the hypothesis stage, it also seriously relies on operator's experience and skill, which results into no publicly recognized and uniform jigging ...

Coal slime waste: a promising precursor to develop highly porous ...

Effective processing and use of coal slime is of great significance to protect the environment and save resources. Different coal slimes (untreated with 43 wt% ash content, crushed and flotation treated with 10 wt% ash content, and precarbonized) were activated with KOH to prepare porous activated carbon. The results show the activated carbon prepared from coal slime with 10 wt% ash had high ...
