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 ...
