The Interesting Evolution of the Coal Industry in AmericaCoal Before the Civil War. In 1840 people began using anthracite coal to make iron. This advance increased the efficiency of the iron furnaces, as well as improved the quality of the iron. By 1860, anthracite produced 56% of American pig iron. Production levels remained high through the years leading up to the Civil War, even though prices fell.
