The Mining of Taconite, Lake Superior Iron Mining District
T I lHE exploitation of taconite, a hard sedimentary rock containing 20 to 35 per cent iron, has had a rejuvenating effect on mining in the Lake Superior Iron Mining District of northern Minnesota, Wisconsin, and Michigan. This development comes at a time when the shipment of highgrade ores obtained by open-pit and shaft mining has passed its peak.
