    In terms of tonnes produced, the beneficiation of iron ore has traditionally been dominated by dense medium separation technology (Iron Ore 2007). The size range for this technology is the same as jigging but heavy media separation, as the name implies, takes place in a heavy or dense medium made up of a mixture of water and ferrosilicon

    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 industries

    Mar 21, 2015 Lean iron ores are normally upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized so that it can be used in an iron making process. Also during the processing of high grade iron ores which do not need beneficiation, generated fines can be pelletized and used instead
