Iron Ore are rocks and minerals from which metallic iron can be frugally extracted. The ores are generally rich in iron oxides and differ in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite, hematite, goethite, limonite or siderite Hematite is also known as natural ore.

The iron-formation contains subordinate intraclastic …

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 also be described as the stacking of sheets of octahedraly ...

Jun 14, 2011 There are many ores of iron found underneath earth and they are known as siderite, magnetite, hematite and limonite. All these are oxides of iron with some more elements associated in small quantities mostly silicates. As iron ores are oxides, refinement of the ore to remove oxygen is necessary before we can expect to get pure iron.
