Characteristics of particle size classification and classified separation for coal gasification fine slag

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects
A considerable volume of coal gasification fine slag (CGFS) has hampered the growth of the coal chemical sector. Carbon/ash separation in CGFS is a prerequisite for efficient treatment and resource utilization. This work focuses on the residual carbon classified separation of CGFS.

Optimizing Confined-Turbulence Conditioning for Enhanced Flotation of Coal Gasification Fine Slag

Minerals
Coal gasification fine slag (CGFS), a major solid by-product of coal gasification, contains substantial unburned carbon. However, efficient carbon–ash separation during CGFS flotation is often restricted by its complex surface properties. This study aims to enhance the flotation performance of CGFS by introducing a confined-turbulence pulp conditioning
