Iron

Iron has been produced from various deposits in Missouri for the better part of 200 years.  Whether, it was limonite and hematite from the sedimentary ores, which were processed in places like Sligo and Maramec, or the magnetite from Iron Mountain and Pea RIdge, it was iron, cast or ductile, or steel that built buildings, railroads, bridges, ships, trains and automobiles.  While iron mining in Missouri has been dormant since 2000, significant reserves remain in the ground and as the cost of transporting overseas production increases, the future looks more promising for deposits in the United States.  For more information about iron contact the Geologic Resources Section at 573-368-2143 or email.
