Triboelectrostatic Beneficiation of Land Filled Fly Ash

To date, commercial beneficiation of fly ash has been performed exclusively on dry “run of station” ash. Recent environmental legislation has created, in certain markets, a need to supply beneficiated ash in times of low ash generation. This, coupled with a requirement in some locations to empty historical ash landfill sites, has created the need to develop a process to beneficiate historically landfilled ash.

Coal beneficiation technology to reduce hazardous

Fly ash emitted from the coal-fired power plant is the major contributor of the outdoor airborne particulate matters (PMs). Coal beneficiation, an industrial process to improve the quality of raw coal by removing ash-bearing components, can be a cost-effective sustainable and clean technology to reduce the emission of hazardous trace metals.
