About Coal – colonialcoal

From highest quality to lowest quality they are: hard coking coal, semi-soft coking coal, and pulverized coal injection (PCI) (or low volatile pulverized coal [LVPCI] injection). Met coal quality can be improved by different washing processes, but only to a certain extent as there is an inherent “coal quality.”
