Australia's hematite DSO from the Hamersley region averages from 56% to 62% iron. Like hematite ores, magnetite ores require initial crushing and screening, but undergo a second stage of processing which relies on the magnetic properties of the ore and involves magnetic separators to extract the magnetite and produce.

The most important iron ores are the iron oxide minerals called hematite and magnetite. While many other minerals contain iron and can be mined - such as the hydrated ore minerals limonite and goethite, and the iron carbonate mineral siderite - the higher concentration of iron in magnetite and hematite make them the two.
Feb 16, 2018 . 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 (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world's iron and steel industries.
The rock is mixed with water and ground in rotating mills until it is as fine as powder. Separation The iron ore is separated from the taconite using magnetism. The remaining rock is waste material and is dumped into tailings basins. The taconite powder with the iron in it is called concentrate. Pellets The concentrate (the wet.
