Modelling of Hard Coal Beneficiation Process Utilising

The dry separation methods for coal beneficiation have been regaining attention in the past decades. A number of improved or newly designed devices have been developed—one of them is a negative pressure pneumatic separator (NPPS). The said method of separation is based on the differences in the physical properties between coal and gangue minerals, such as the grain density, size, and shape.

Beneficiation of coal using supercritical water and carbon

Apr 30, 2020 The coal beneficiation is demonstrated in 200–400 C range at 143 bar using a semi-continuous process without needing any mineral acid or organic solvents by studying the sulfur removal. Carbon dioxide extraction at 350 C is effective similar to the typical hydrothermal extraction which was most effective at 290 C.
