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 12.72 wt % compared to dry magnetic separation.

Jul 01, 2019 The concentration of metals in fly ash varies greatly depending on the incineration facilities and sampling time. Iron oxide is typically the highest concentration transition metals in combustion systems and is known to catalyze PCDD/Fs formation (Nganai et al., 2008).The wide distribution of iron concentration raises the question of how the metal concentration affects total PCDD/Fs yields.

Unfortunately, fly ash drying is made challenging as a result of the dusty nature of fly ash. As such, dust suppression via agglomeration is often employed prior to drying. Agglomeration is also frequently used when working with a dry fly ash material in order to improve its handling (along with other) characteristics.
