Mining | Tennessee Encyclopedia
Early national census reports did not separate iron ore mining from iron production, but most early manufactories were associated with mines. By 1840 the U.S. Census reported iron production from eighty-two furnaces, bloomeries, forges, and rolling mills in East Tennessee; forty-seven in Middle Tennessee; and four in West Tennessee.
