Coal Fines Problems In Washing Coal

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.

That means coal ash will be a problem — for everybody — for the foreseeable future. "It's not about the coal. It's about the water," says Tiffany Haworth, the executive director of the Dan River Basin Association. "We can't do much about coal that was burned 50 years ago. We just have to suck it up and do the best we can with that.

What is Coal Washing? Definition from Safeopedia

Coal washing is a process that is undertaken in a coal washery or coal preparation plant (CPP) where coal is refined or cleaned of impurities. Coal washing involves using water, mechanical techniques and relies on gravity and the difference of density between coal and it's impurities which are usually more densely packed due to the fact that they are inorganic.
