The water loss in the concentrator (the moisture in the product) accounts for only %. In iron ore concentrator plants, which have higher product mass yield than copper plants, the water consumption increases to 15% at the concentrator and decreases to 85% at the tailings dam. In both plants the water consumption in the tailings dam is high.
· Sintering: A Step Between Mining Iron Ore and Steelmaking. The USGS defines iron ore as 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 (Fe3O4) and hematite (Fe2O3). It''s a major ingredient in steel.
