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 and received it in 1837. By the time the patent was sealed, Yniscedwyn was producing about 35 tons of iron using anthracite only as a fuel. Inspired both by Geisenhainer and Crane (whose success was closely followed by the LC&N), experiments in the US continued. Baughman, Guiteau and Company used an old furnace near Mauch Chunk to produce some anthracite iron during late 1837. They built another experimental furnace nearby, which was worked for about two months during fall and winter 1838 and for some time in 1839, but mechanical deficiencies led them to abandon the furnace at the end
