Ore Deposits Formed by Oxidation and Supergene Enrichment When ore deposits are exposed to the oxidation zone they are weathered and altered with the country rocks. The surface waters oxidize many ore minerals and yield solvents that dissolve other minerals. An orebody thus becomes oxidized and generally leached of many of its valuable materials down to the groundwater table, or to.View More
Lateritic weathering of metamorphosed Proterozoic banded iron formation (BIF), locally named itabirite in Brazil, produced large deposits of iron ore. At the Capanema iron ore mine in the Quadrilatero Ferrifero in Minas Gerais state (southeast Brazil), the BIF is a bedded metasedimentary rock composed essentially of layers of hematite kenomagnetite alternating with layers of quartz.View More

The world's resources are dominated by low grade ore, though current world production of iron ore is largely by supply from deposits of high grade ore composed of either rocks of massive hematite or pisolitic goethite. World iron ore production in 2013 was 2.95 billion tonne, with the major producers being China, Australia, and Brazil.View More
Mar 30, 2018 A review of iron ore types can be found in recent works of Hagemann et al. . In terms of texture and physical hardness, irrespective to their mineralogy, iron ore is described as hard, medium, soft and powdery, or dust (Clout Simonson, 2005 Hagemann et al., 2008). Hard ore displays variable physical appearances from massive or banded to.View More
Uses of Hematite (Iron Ore) Hematite is the world’s most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.View More
Descriptions of major ore deposits world wide. The Cuyuna Range iron and manganese deposits are located some 100 km SW of the Mesabi Ranges in east central Minnesota, USA defining a district that is approximately 110 x 32 km of tightly folded iron formation. Mining commenced in the district in 1911 and finished in 1985. Historic mines include Croft and Portsmouth.View More
Oct 17, 2019 After the initial deposition of BIF deposits are often further enriched in iron by either of supergene enrichment – where weathering saw the leaching of soluble materials hydrothermal processes.
