Anthracite Coal Characteristics and Applications

29/01/2020· Anthracite coal, mined from the planet's oldest geological formations, has spent the longest time underground. The coal has been subjected to the most pressure and heat, making it the most compressed and hardest coal available. Hard coal contains greater potential to produce heat energy than softer, geologically "newer" coal. Common Uses . Anthracite also is the most brittle among coal …

Anthracite - Wikipedia

Anthracite, also known as hard coal, is a hard, compact variety of coal that has a submetallic luster.It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals.. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 86% and 98%.
