Metallurgical coal also called met coal is an important raw material used in the steel-making process, although very small amounts of coal relative to the amount used for electricity are needed. The coal used to make steel is heated without air in an oven at temperatures of as much as 2,060F 1,125F, until most of its volatile matter is released.

Hard vs. Soft Coal falls into two main categories hard and soft. Soft coal is also known as brown coal or lignite.China produces more hard coal than any other country by a factor of about three. The whopping 3,162 million metric tons of hard coal produced by China dwarfs the output of the second and third-ranked producersthe U.S. at 932 million metric tons and India at 538 million metric.

At present, a large proportion of this type of coal is used by the power industry and in general accepted as ROM coal, or after minimal cleaning at 34 ash, because of various market issues. These coals could also be used in coal blends for producing metallurgical coke after washing to below 18 ash level.

2020-5-31Coal is primarily used as fuel to generate electric power in the United States. The coal is burned and the heat given off is used to convert water into steam, which drives a turbine. In 2012, about 39 percent of all electricity in the United States was generated by coal-fired power plants, according to the U.S. Energy Information Administration.
