mining and refining of iron ore
Ore Mountain, a mile west of the furnace, was the source of the iron ore that was refined to pig iron. Mining was relatively easy because a four foot deep layer of raw ore lay just below the surface. Workers needed only to clear away trees and topsoil to reach the ore, the ore was ready for the furnace.
