Iron Ore in India, Types, Uses, Distribution, World Map
Iron Ore is a type of rock that contains iron minerals, mainly hematite and magnetite. It is a vital raw material for the production of steel. The ores are rich in iron oxides, which range in colour from dark grey to bright yellow to deep purple to rusty red. The most common iron minerals are magnetite, hematite, goethite, limonite, and ...

The Brockman Iron Formation in this province is the most significant host for high-grade hematite iron ore deposits. Magnetite is an iron oxide mineral that is generally black and highly magnetic. The latter property aids in the beneficiation of magnetite ores. Magnetite contains 72.4% Fe by molecular weight, which is higher than hematite, but ...
