Anthracite is a type of coal known for its high carbon content, typically ranging from 86% to 97%. It is the hardest and most energy-dense form of coal, making it an efficient fuel source. Anthracite burns cleanly with a low level of smoke and emissions, which makes it a preferred choice for heating and industrial applications. This coal is primarily found in regions like Pennsylvania in the United States and parts of China. Due to its high energy content, anthracite is often used in residential heating, power generation, and as a reducing agent in metallurgical processes.
