Role of coal cleaning in control of air toxics ScienceDirect

1994-8-1  This coal was crushed to two different topsizes (100 mesh and 200 mesh) to investigate the effects of crushing on the selective oil agglomeration process. For the Illinois No. 5 seam coal, selective oil agglomeration provided significant reductions in all elements studied except cobalt, which increased 11%o in the 100 mesh product.

Advanced physical coal cleaning to comply with potential

Therefore, to remove the pyrite using physical coal cleaning techniques, the pyrite must be liberated by grinding the coal to ultrafine particle sizes. Fortunately, the coals being fed to pulverized coal boilers (PCB) are already ground to a very fine size, i.e., 70% passing 200 mesh.
