· A technology for dry beneficiation of fly ash generated at coalfired electric heat and power plants has been developed. Several samples of fly ash from different coalfired heat and power plants were studied. The studies of ash samples material composition showed, that unburned carbon content in the samples varied from 5 to 20 %.

Coal Ash In general, a 1,000 MW station using coal of 3,500 kilo calories per kg and ash content in the range of 4050 per cent would need about 500 hectares for disposal of fly ash for about 30 years' operation. It is, therefore, necessary that fly ash should be utilised wherever possible to minimize environmental degradation.
