Question

what is anthracite and how is it used​

Answer 1

Answer:

Anthracite, often referred to 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 used primarily for heating residential and commercial buildings in the northeastern region of Pennsylvania, where much of it is mined.
