Process for scavenging iron from tailings produced by ...

A process for recovery of iron from iron ore consisting essentially of subjecting the ore to cationic gangue flotation to produce a flotation concentrate as underflow and flotation tailings as overflow, and subsequently scavenging iron from said tailings by means of a wet high-intensity magnetic separator, whereby a magnetic concentrate of increased iron content and a magnetic tailings of reduced iron content are obtained.

MIDREX® Process - Midrex Technologies, Inc.

As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a high H₂ and CO content. These gases react with the iron oxide in the iron ore and convert it to metallic iron, leaving H₂O and CO₂.
