    Anthracite is a high-rank coal representing a coal that has been subjected to the highest grade of metamorphism. Anthracite is shiny black hard and brittle (see Figure 2.8) and has the highest fixed-carbon content (approximately 86–98 ).Due to its low volatile matter (2–12 ) anthracite s combustion process is slow. Most anthracites have low-moisture content (about 3–6 ) and their
