Iron Element History, Uses, Facts, Physical Chemical

Chromite is a chromium ore that contains iron. Lodestone is a form of magnetite that exhibits natural magnetic properties . Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars, where it is the last element to be produced with release of energy before the violent collapse of a supernova, which scatters the iron into space.

What Are the Main Uses of Iron Ore? Reference

Iron ore are the rocks or minerals by which metallic iron is derived. Iron ores that carry a high quantity of hermatite or magnetite can be fed directly into blast furnaces in the iron production industry. The business of mining iron ore is a high volume, low margin industry because of the low value of iron.
