Coal grinding is preparatory process to a creating mixture for combustion in boilers at thermal power plants. To a high-quality fuel …Bituminous coal is softer than anthracite and much more ultra-fine particles will emerge after grinding. The ultra-fine coal particles finer than 10 μm are usually difficult to float (Polat et al., 2003, Forbes, 2011). So grinding of oxidized bituminous coal might deteriorate flotation performance due to the increase of ultra-fine particles.
