• Iron Ore: From Depletion to Abundance Science

    Following World War II, Americans feared their iron ore supplies were depleted. The steel industry attempted to increase supplies by exploring foreign countries for new, highgrade hematite ores and experimenting with technology that upgraded lowgrade domestic taconite ores into acceptable, but apparently uneconomical, pellets. Government did little at first, but the Korean War renewed fears
