Fly Ash Beneficiation Process

US20040231566A1 - Process for Fly Ash Beneficiation

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.

Fly ash - Wikipedia

Fly ash or flue ash, coal ash, and also known as pulverised fuel ash in the United Kingdom, or coal combustion residuals (CCRs), 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

how processing of fly ash

Fly ash has pozzolanic properties, meaning that it reacts with lime to form cementitious compounds. It is commonly known as a supplementary cementitious material. The properties of Fly Ash may vary widely, both physically and chemically, depending upon the nature of coal, the efficiency of coal combustion process and the selection process.
