Beneficiation of Iron Ore Mineral Processing MetallurgyMagnetic Belt Cobbing Technology for Upgrading Coarse
Beneficiation of Iron Ore and the treatment of magnetic iron taconites stage grinding and wet magnetic separation is standard practice This also applies to iron ores of the non magnetic type which after a reducing roast are amenable to magnetic separationCertain 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
