Iron Ore | Geoscience Australia

May 03, 2017· Mining and processing hematite and magnetite ores. Highgrade hematite ore is referred to as direct shipping ore (DSO) because, once mined, the ore goes through a relatively simple crushing and screening process before being exported for use in steel making. Australia's hematite DSO from the Hamersley province averages from 56% to 62% iron.

Different Types of Iron Ore Mineral Processing Metallurgy

Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times highgrade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

Hematite (or haematite) University of Auckland

Large ore bodies of hematite are usually of sedimentary origin, and it is widely distributed in sedimentary rocks as a cement. High grade ore bodies can be found in metamorphic rocks as a result of contact metasomatism. Hematite is also as an accessory mineral in igneous rocks. The red colouring of soils all over the planet is due to hematite.

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.

While the first iron ore was likely meteoric iron, and hematite was far easier to smelt, in Africa, where the first evidence of iron metallurgy occurs, limonite is the most prevalent iron smelting, as the ore was heated and the water driven off, more and more of the limonite was converted to hematite.
