Opportunities For Fine Coal Utilisation

Opportunities For Fine Coal Utilisation

Opportunities for fine coal utilisation 7 A considerable proportion of material extracted during coal mining is rejected. This includes material that is largely a by-product of coal processing, having significant energy content and small particle sizes including substantial amounts below 0.15 mm. Such fine coal is difficult to handle and poses
