Our iron ore wet processing plants are proven to successfully deal with silica and alumina contamination in the iron ore, resulting in an increase in the Fe value of the iron ore thereby increasing the efficiency of the steel production process. Silica requires very high temperatures in the kiln, therefore, increasing energy costs when it is present in the feed to the kilns.

Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used.

Iron Ore Statistics And Information Usgs

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.
