Tailings Wikipedia

Coal refuse (also described as coal waste, coal tailings, waste material, culm, boney, or gob) is the material left over from coal mining, usually as tailings piles or spoil tips.For every tonne of hard coal generated by mining, 400 kilograms of waste material remains, which includes some lost coal that is partially economically recoverable. Coal refuse is distinct from the byproducts of

THE INDUSTRY CoalTech Waste Coal Fines Plant

At present, vast amounts of coal discards lie in open-air lagoons as wasted by-products. It is estimated that over 30 billion metric tons of coal tailings are available in the top 10 coal producing countries. As a result of continuous coal mining, these countries have accumulated abundant stockpiles of coal

A Cost-Effective Solution for this Coal Preparation Plant

The Macquarie Coal Preparation Plant prepared coal from the West Wallsend Colliery in the Newcastle coal fields. Before coal washing stopped at the plant, the company needed to cap its tailings storage facility while it also continued to operate. The challenge was how to progressively cap a facility that was still receiving tailing deposits.

Reducing the environmental impact of coal-washing practice

All Australian coal for export is washed — that is, the low-grade high-ash material is separated out and disposed of at the washery site. The coarse rejects are generally placed in embankments and the tailings are pumped into settling ponds. These methods of waste disposal can create environmental problems. In addition, they represent a significant energy loss, because about one-third of the
