Magnetite Magnetite (Fe3O4), like hematite (Fe2O3), is a form of iron ore. It is a highly magnetic substance used primarily in steel manufacturing and coal washing. There are more than 20 identified magnetic deposits and prospects located across South Australia, Western Australia, Queensland and Tasmania.

ABSTRACT Bikilal iron ore deposit is a Kiruna-type magnetite – ilmenite deposit in West Wollega Western Ethiopia. It is formed within syn-post tectonic intrusive gabbroic complex that intrudes the Precambrian gneiss. Bikilal gabbroic intrusion comprises olivine gabbro in the center, hornblende gabbro and hornblendite as dominant rock at the periphery of the intrusive as well as …

Sulphide and oxide iron facies coexist, both on a regional as well as on a micoroscopic scale. Later hydrothermal episodes affected the deposits and rearranged and enriched the ore minerals. The altered enclosing rocks display greenschist facies metamorfphism, whereas the ore minerals and ore texture seem to be little affected.

Hematite ore is typically higher-grade than magnetite ore, with approximately 60% contained iron whereas magnetite ore has grades in the order of 30% contained iron. However, magnetite can be converted to a higher-grade (approximately 60–70%; Table 2) and lower-impurity product that is preferred for electric arc furnaces.

What is Iron Ore? Earth''s most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). These iron ores have been mined to produce almost every iron and steel object …
