Coal gasification fine slag is a kind of solid waste with low resource utilization rate. The complex embedding of residual carbon and inorganic minerals (ash materials) is the main reason restricting the efficient resource separation and utilization of residual carbon or ash materials. Hydrophobic–hydrophilic separation (HHS) is a separation technology in which …

Air classifiers have the ability to separate powders as coarse as 80 mesh (180 μm), and as fine as 2–3 μm. The fineness of air-classified products is controlled by a precise balance among the quantity of rejector blades, the speed at which the rejector blades operate, the velocity of the airflow and the rate at which the material is fed.

However, a large amount of coal gasification fine slag (CGFS) is generated during this type of gasification process. In 2021, the Ningdong Energy Chemical Industry Base in China produced about 3.2 million tonnes gasification fine slag [6].As an industrial solid waste with a high carbon content (about 20 %−40 %), gasification fine slag is mainly buried and landfilled [7].
