Magnetic Floatation Iron Ore Concentrate Upgrading

The tailings produced by iron ore flotation are treated by the wet high-intensity magnetic separation for iron scavenging. The magnetic separator is operated with air-gap field strength of 2-100, and preferably 5-10 kg. Magnetic concentrate from scavenging is reprocessed by flotation to improve iron recovery. Thus, tailings from the cationic gangue flotation containing 36.2 pct fe were fed into
