Iron Ore Mining Iron ore, is the basic raw material for steel production. Over 90% of the ,iron ore, is presently extracted by open pit surface ,mining, tech- niques with the remainder being recovered from deep vertical shaft mines. Production is concentrated in the North Central states with over 60% of the total amount originating in Minnesota.
