Magnetite and Carbon Extraction from Coal Fly .
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 to wt % compared to dry magnetic separation.

Desulfurization of low rank coal copyrolysis with .
· However, dry magnetic separation process has no effect on the separation of low rank coal sample pyrolysis without Fe powder. Therefore, the low rank coal sample pyrolysis without Fe powder was not separated by the magnetic separator and directly forwarded to the analysis of sulfur content and forms.

Desulfurization of low rank coal copyrolysis with .
In this paper, low rank coal copyrolysis with reduced iron powder (Fe powder) and then followed by dry magnetic separation was used to reduce the sulfur content of low rank coal. After dry magnetic separation, the organic sulfur content can be reduced from % for low rank coal before the pyrolysis to % for the coal after 700 °C copyrolysis with Fe powder at the coal/Fepowder mass ...
