THE INDUSTRY CoalTech Waste Coal Fines Plant

Coal fines or tailings are a wasteful by-product of the coal mining process that have a low market value, are generally expensive to dispose of, and are left in stockpiles or slurry ponds at or near mining sites. At present, vast amounts of coal discards lie in open-air lagoons as wasted by-products. It is estimated that over 30 billion metric

Treatment of coal tailings ScienceDirect

2013-1-1  Slurry tailings are usually the product of a de-sliming process in the coal preparation plant, where material below a size between 1 and 0.1 mm is separated. This sizing process is achieved using large quantities of circulating water, sometimes up to 10 m 3 /h of water for every tonne of fine raw coal to be removed, prior to the main gravity-based coal preparation processes.

Coal Beneficiation an overview ScienceDirect Topics

Some coal tailings are transferred to preparation plants for recovery of coal contained in the waste. Currently about 9% of generated waste is utilized in this way. The residue after the recovery of coal is re-dumped or used, for example in hydraulic backfilling or the building construction materials industry.

2017-6-16  Room-and-pillar mining may leave as much as 60 percent of the coal in supporting pillars after initial mining. Later, some of these pillars are removed as equipment retreats from the mined area. Long-wall mining permits increased recovery of coal by extracting coal along a single face which is much longer than used in room-and-pillar mining.
