Coal Industry. Recovery of fine coal – which is generally minus 4mm (1/8 inch) material – began in most industrialized countries only at the start of the 1950's. The earlier processing methods resulted in enormous tonnages of coal tailing dumps and coal lagooned material available for economic re-treatment.
Oct 08, 2020· Similar to ash left behind from burning logs in a fireplace, burning coal for power produces coal ash. While Duke Energy has upgraded technologies in recent years to store ash in lined landfills, the industry standard when the coal plants were built was to move the ash into a storage pond called an ash basin.
Plants to recover salable coal from waste dumps and lagoons are simple and straightforward to operate and can produce coal at a feasible cost using the DEC Flotation Column. The recovered coal will have an ash content of less than 10% from a feed of 25-45% ash. The photograph on this page shows a typical recovery plant utilizing 6 DEC …
