Jan 07, 2018· Bauxite and iron ore are two such types that are found naturally on earth. Bauxite is also known as aluminum ore and contains aluminum bearing minerals. Iron ore is a type of rock from which we can extract iron. The main difference between bauxite and iron ore is that bauxite is a source of aluminum whereas iron ore is a source of iron.

Iron ore. Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH)·n(H 2 O)) or siderite (FeCO 3).

Hematite is also known as "natural ore". The name refers to the early years of mining, when certain hematite ores contained 66% iron and could be fed directly into blast furnaces. 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.

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.

Australia's iron ore production has seen strong growth over the past five decades and over this period of time a very significant change in the blend of Australian iron ore production has occurred. Initially there was a clear preference for the mining of Premium Brockman

Goethite is a common mineral, and is a frequent matrix material for other more aesthetic minerals. It is usually a dark, uninteresting mineral, though specimens from a handful of locations (especially Colorado) are remarkable for their delicate and beautiful crystal growths and velvety botryoidal growths. Goethite is also frequent as black crystal sprays that form within geodes on drusy Quartz.

The iron by its own is usually found in the structure of magnetite (Fe3O4), hematite (Fe2O3), goethite, limonite or siderite. Hematite is also identified as "natural ore". The nomenclature dates back to the early years of drawing out, when certain hematite ores comprised 66% iron and could be fed reliably into iron edifice blast furnaces.
