Alpha Natural Resources is a large American producer of metallurgical coal ("met coal") for the industrial production of steel and iron and low-sulfur thermal coal ("steam coal") to fuel steam boilers for the production of electrical power. In November, 2018 the company was acquired by Contura Energy. The company also provides industry services relating to equipment repairs, road construction and logistics, with domestic operations and coal reserves within the states of Virginia, West Virginia, Kentucky, Wyoming, Utah, Illinois, Tennessee, and Pennsylvania. Alpha Natural Resources does not produce all of the coal it sells; much of the coal sold by Alpha Natural Resources is purchased from independent mining operations and then resold in the worldwide market.
