Anthracite Geologically, the largest most concentrated anthracite deposit in the world is found in the Lackawanna Coal Mine in northeastern Pennsylvania, United States in and around Scranton, Pennsylvania. Locally called the Coal Region, the deposit contains 480 square miles of coal bearing rock which originally held 22.8 billion short tons (20.68 billion tonnes) of anthracite. (The geographic region is roughly 100 miles (161 km) in length and 30 miles (48 km) in width.) Because of historical mining and development of the lands overlying the coal, it is estimated that 7 billion short tons (6.3 billion tonnes) of minable reserves remain. The
Anthracite iron States, in the principal control and supervision of Ironmaster David Thomas who had begun experimenting with attempts to use locally available Wales anthracite deposits as early as 1820 soon after he became in charge at Yniscedewin Iron Works in Wales. About this 1837-38 timeframe experiments were also being made in Pennsylvania near Port Carbon, and in Mauch Chunk, but with overall better success than in Wales. White, Hazard and the LC&N Co. had begun systematic experiments to smelt using anthracite in two furnaces in Mauch Chunk in 1832-1837 with intermittent but sporadically improved successes using cold blast processes with two
