Fly Ash is collected by electrostatic precipitators or bag filter collection. Fly ash is dust-like particles from the flue gasses from power station furnaces fired with coal at about 1400 °C. Fly ash is a fine powder, which is mainly composed of spherical glassy particles.

South Africa only produces Class F Fly Ash but it was proved in studies around the world that due to that it is a pozzolanic material, it reacts with lime/cement to form cementitous compounds .
Eskom Rotek Industries is a wholly owned subsidiary of Eskom Enterprises, which in turn forms part of Eskom Holdings. Eskom is home to 14 active coal-fired power stations with an additional station still under construction, which consume an estimated 120 million tons of coal per year, resulting in the production of about 36 million tons of ash.
A total of 5 kg sample of fly ash was also collected every hour for a period of 5 days from the hoppers at the various Steam Stations. To obtain a 1kg representative fraction, the bulk fly ash sample was coned, quartered and riffled.
Ulula Ash, suppliers of Coal Fly Ash to the Southern African market who have a long term contract with Eskom for the removal of Coal Fly Ash from Kriel Power Station.
Fly ash Fly ash is hydropholic and can be used as a cementitious additive. The ash, which is collected from chimney filters in coal-fired power plants, is composed of vitreous silica, alumina, iron oxide and lime. They can be used as a partial substitute for clinker and thus help to reduce CO2 emissions.
The amount of fly ash available in South Africa (20 million tons) significantly exceeds cement clinker capacity (10 million tons). Driven by the need to enhance the properties of fly ash the finer more reactive fraction was initially recovered from the last 3 fields of the array of electrostatic precipitators.
