Certain material types currently considered to be uneconomic were upgraded using the dry magnetic cobbing process to produce a millable ore concentrate. Best magnetic iron recoveries after cobbing ranged from approximately 78 to 95 pct for the Tertiary feed and 50 to 95 pct for the secondary crusher feed. The tests indicate that the lean-grade ore types (lc2 and lc5) lend themselves to dry magnetic cobbing
