This coal is predominately sold to steel mills for use in the production of pig iron from iron ore in the blast furnace process. It is recognized as a cheaper alternative for coking coal which has been used traditionally in the blast furnace process. LV PCI coal has high content of carbon and energy but low output of ash and sulphur.

4. HARDGROVE GRINDABILITY INDEX (HGI) • The Hardgrove Grindability index is designed to determine the ease with which coal can be pulverized. • It measures the grindability of coal and is a qualitative measure of coal. • It provides information for determining grinding power consumption and pulverizing capacities.
