Hematite

Hematite Mineral Description. Hematite is an iron-oxide mineral of the Oxides and Hydroxides group, with structural formula [alpha-Fe 2 O 3].The structure is similar to that of corundum, and consists essentially of a dense arrangement of Fe 3+ ions in octahedral coordination with oxygens in hexagonal closest-packing. The structure can …

Iron Ore, Types, Uses, Distribution in India & 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 siderite.
