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 iron.
