Metallurgical (met) coal (sometimes referred to as coking coal) is a naturally occurring sedimentary rock found within the Earth's crust. Categories of met coal include hard coking coal, semi-hard coking-coal, semi-soft coking coal and pulverized coal for injection (PCI). These apply to the di˜erent quality grades of met coal,

Geologists also classify coal types according to the organic debris, called macerals, from which the coal is formed. Macerals (microscopic organic constituents found in coal) are identified (microscopically) by reflected light - the reflective or translucent properties of the coal indicating the individual component macerals
