Frequently Asked Questions | The Magnetite Network

Hematite, or Direct Shipping Ore, has a different chemical make-up (Fe2O3) than Magnetite (Fe3O4). Magnetite contains less iron than hematite and is, therefore, of little value in its raw state. In order for magnetite to be used in steel production, the magnetite ore needs to be processed (beneficiated) in an extensive jobs and.

Why is hematite used over magnetite? Magnetite has more iron .

While magnetite ore requires more treatment than hematite ore, steel products made from magnetite ore are typically of higher quality than those from hematite ore. That is because magnetite ore has fewer impurities than hematite ore. To a certain extent, the higher cost of processing magnetite ore is.

Hematite - Wikipedia

Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F). Hematite is colored black to steel or silver-gray, brown to reddish brown, or red. It is mined as the main ore of iron. Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular.

Iron Ore - AIMR 2011 - Australian Mines Atlas

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.

Page 1 BODIL ELISABETH MONSEN IRON ORE CONCENTRATES .

Oxidation of magnetite. Hematite and magnetite are the most common iron ore minerals, and both are included in the present investigation. Reduction of magnetite is known to be very slow compared to reduction of hematite. However, magnetite becomes an interesting iron ore mineral for the Elkem Polar Process after.

Iron Ore - Mining Artifacts

The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite, limonite or siderite. . Mining and processing of banded iron formations involves coarse crushing and screening, followed by rough crushing and fine grinding to reduce the ore to the point where the crystallised magnetite and quartz.
