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 …

A SUMMARY OF IRON ORE DEPOSIT CHARACTERISTICS IN THE PILBARA CRATON The main host rocks to iron ore in the Pilbara Craton are the thicker and generally more iron-rich BIF units of the 3022-3016 Ma Cleaverville Formation, with only minor iron ore hosted by older BIF units of the Kangaroo Caves and Paddy Market Formations.
Most are now employed in government ministries. A fluid-inclusion laboratory was established under the UNDP scheme, and ore geneses and mineral parageneses of a variety of ore deposits in Myanmar were …
A complication of ore reserves and average grade on various Fe ore deposits over the world demonstrates that a number of large and high-grade Fe deposits belong to BIF-associated and derived deposits whereas some other types of Fe deposits, such as orthomagmatic, IOA-type, and skarn, contain gigantic deposits.
The most important of these are the Transvaal basin on the Kaapvaal craton that contains economically important iron ore deposits; the Congo basin; and the West African basin, with its thick late ...
2. Iron Ore Deposits Iron ore deposits are known to occur in sedimentary, hydrothermal, and magmatic environments, but production today is almost entirely from three types of deposit: deposits related to Precambrian banded iron formations provide about 90% of all iron ore mined, and the remainder is derived from metasomatic skarn and magmatic
