1991-9-10 This patent describes a wet process for fly ash beneficiation. It comprises mixing a fly ash material having cenospheres with a dispersant and water to form a primary slurry from about 5 to about 35 percent by weight fly ash material; allowing the primary slurry to settle and removing the cenospheres floating in the primary slurry for separating and collecting the cenospheres having a density below

2017-1-1 The STET process has a long-proven track record of producing large quantities of consistent pozzolan from high LOI fly ash. It has a modest capital cost relative to thermal beneficiation. The unit is relatively small with modest installation requirements, and it is well suited for smaller power plants.

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.
