Reducing the environmental impact of coal-washing

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

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
