magnetite in coal breakers

In this study enrichment methods for coal fly ash CFA from Omsk thermal power station No 4 TPS4 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 1048 to 1272 wt compared to dry magnetic

magnetite in coal breakers A coal breaker is a coal processing plant which breaks coal into various useful sizes Coal breakers also remove impurities from the coal and deposit them into a culm dump The coal In these wet separators a very dense medium such as magnetite is introduced into an agitated mixture of
