In this work, goethitic iron ore particles were subjected to thermal processing in a fixed bed reaction system under inert nitrogen atmosphere. The objective of this work was to give an insight into the types and concentrations of nonferrous. Manuscript received February 10, 2015; revised January 26, 2016.
generated from magnetite based iron ore due to presence of goethite. In hematite ore, the percentage of goethite varies from 1050% depending on Fe value of the rom ore. Low grade ore contains high goethite in comparison with high grade ore. Kaolinite presents in .

The BIF contains highlyrated haematite and magnetite and lowgraded goethite. Carbonates, silicates, phosphorous and chert contaminants are the consociated gangue minerals. Openpit mining method and processing at the Paraburdoo iron ore deposit. The Paraburdoo iron ore project is an openpit operation which utilises the truck and shovel method.

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite, limonite or .

Iron ore. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel —98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".

This processing works to transform raw, mined iron ore into a concentrated powder suitable for pelletizing. In addition to mined iron ore, other sources of iron, such as flue dust collected from blast furnaces, or the dust produced at mine sites, is also frequently pelletized so it .
The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe 3 O 4 ). Magnetite ore requires complex processing to separate magnetite minerals from other minerals in the ore to produce an almost pure magnetite concentrate with an iron content of between 68% Fe and 70% Fe that is highly sought after by steel makers.
