Экономическая и экологическая целесообразность выделения ценных компонентов из зол уноса тепловых электростанций Южно-Африканской республики

Abstract

The possibility of extraction of valuable components (magnetic fraction, unburned coal, floating microspheres) from the fly ash, produced by three South-African thermal power stations, in order to use them in different sectors of industry is considered in this article. The comprehensive research of fly ash samples from three TPS (MALTA, KRIEL, MATIMBA) contained sieve separation, calcination and extraction of magnetic fraction and floating microspheres. As a result, a conclusion was made that the extraction of valuable components from that ash isn't economically expedient, but the fly ash itself could be used as an additive for building materials.
