Separation Technologies, LLC (ST) operates fly ash beneficiation facilities that produce high quality pozzolan, ProAsh(R), from poor quality fly ash. Its patented electrostatic separation process reduces the carbon content of fly ash to produce a low loss on ignition (LOI) product used as a partial portland cement replacement in concrete products.

In searching for a low cost adsorbent for mercury removal from flue gas, this study focuses on the utilization of unburned carbons from fly ash as the substitute material for the costly activated carbons. In this first paper of the series, various separation technologies are introduced for the extraction of unburned carbon from different sources of fly ash.

Our patented electrostatic separation system consistently removes high-carbon particles from fly ash and enables the recovery of BTUs lost to NO x emission controls. The option to use this otherwise wasted material provides power producers a solution to their fly ash management program and can measurably add value to coal use.

The fly ash from most of the U.S. bituminous coals contains 15 to 20 weight percent iron oxides, 50% or more of which can be recovered by dry magnetic separation as a high density fraction. The density of this fraction is 3.5 to 4.0 g/cm/sup 3/, depending on the fly ash.

7/17/2017· Fly ash is a byproduct from coal-fired power plants that is frequently used as an admixture in concrete to replace a portion of the Portland cement. Using fly ash in concrete is environmentally beneficial because it reduces the Portland cement (a major contributor of CO2) required in concrete.

Q: Does fly ash affect concrete bleeding? A: A study by the Portland Cement Association compared the bleeding of concretes containing 10 different fly ashes with two control concretes containing no fly ash. In the study, Class C ashes reduced bleeding much more than Class F ashes. The ability to reduce bleeding, for most of the fly ashes, was related to a reduction in the amount of water ...
