Virginia Geological Survey Iron

In the nineteenth century, production became concentrated in belts of rich iron ore along the flanks of the Blue Ridge mountains, and in the sandstones of the Valley and Ridge Province. In Virginia, most of the iron was extracted from limonite (Fe 2 O 3 +H 2 O), hematite (Fe 2 O 3), magnetite (Fe 3 O 4), and carbonate deposits (siderite, FeCO 3), with limonite as the major source of

Virginia Geological Survey Civil War Iron

Typically the iron occurs where a thick shale bed containing disseminated pyrite overlies limestone. The iron weathers from the pyrite into an acidic solution that percolates downward into the pores of the limestone, where the dramatic change in pH causes it to precipitate as limonite (Gooch, 1954).

Hematite: A primary ore of iron and a pigment Geology

Iron Furnace: In the 1700s and 1800s, small mines in the eastern United States produced hematite which served as the primary iron ore of the region. The ore was processed by heating it by burning charcoal in simple stone furnaces. The iron ore deposits were small and difficult to exploit.
