The Process of Iron Smelting: Turning Iron into Usable Metal
The process of smelting iron has been around for centuries, but in the early days of America furnaces were built in order to refine enough iron to build a country on. Getting the Ore The business of Catoctin Furnace in Frederick County, Maryland, was producing iron and the furnaces and workers did that for more than 125 years.
