Iron Ore Processing Flotation From United States

There is disclosed a process for scavenging iron from tailings produced by the flotation beneficiation of iron ore. This process includes the step of scavenging the flotation tailings using wet high-intensity magnetic separation (WHIMS). There is also disclosed a process for increasing the recovery of iron ore in a flotation beneficiation process

    Iron Ore Statistics and Information - USGS

    Iron Ore Statistics and Information. Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel
