2017-1-16In coal combustion to generate electric power and process heat the sulfur is emitted as SO2 which is seen as one of the main causes of acid rain. This effect has led to an interest in the three main methods of removing coal sulfur coal cleaning in-bed desulfuriation and flue gas desulfuriation.

In this study enrichment methods for coal fly ash CFA from Omsk thermal power station No. 4 TPS-4 were investigated. The magnetite and unburned carbon concentrates were obtained by magnetic separation and flotation methods. The wet magnetic separation used in the study increased the magnetite content in the magnetic fraction from 10.48 to 12.
