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.
The chemical composition and ignition loss of the bottom ash and fly ash are summarized in Table 2. Prior to the pretreatments, bottom ash and fly ash were mixed at a ratio of 5:1 on a dry weight basis (based on actual data for landfill waste in Sapporo). This ash mixture is subsequently referred to as "BF ash." Methods
