Abstract. 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 ...
Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash.

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.
The STET separation process with feed preprocessing equipment for drying and deagglomerating landfilled fly ash is an attractive option for ash beneficiation with significantly lower cost and lower emissions compared to other combustion- and flotation-based systems.
11/25/2004· A process is disclosed for converting low reactive fly ash to a highly reactive pozzolanic material by heating the fly ash until at least a portion of the fly ash melts; then rapidly cooling the fly ash. The resulting vitrified fly ash has improved cementitious properties relative to untreated fly ash.
9/10/1991· A wet process for the beneficiation of a fly ash by-product has the following steps: a) forming a slurry mixture of a fly ash material and a liquid; b) gravitationally separating and collecting a first material fraction of the fly ash having a density less than the liquid by skimming off floating slurry material; c) separating a first magnetic fraction from the slurry by subjecting the slurry ...

Strategies for the recovery of wet-stored fly ash for use in concrete are different from the processing of dry fly ash. Typically, these are single-process steps, such as air classification to increase fineness, or electrostatic separation to reduce LOI. The recovery of ash from a stockpile or pond is closer to a mining or quarry operation.
