Iron ore (fines) - Cargo Handbook - the world's largest ...

Iron is the most magnetic of the three. The mineral magnetite (Fe 3 O 4) is a naturally occurring metallic mineral that is occasionally found in sufficient quantities to be an ore of iron. The principle ores of iron are Hematite, (70% iron) and Magnetite, (72% iron). Taconite is a low-grade iron ore, containing up to 30% Magnetite and Hematite.


Iron Ore - AIMR 2011 - Australian Mines Atlas

Iron (Fe) is a metallic element which constitutes about 5% of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4).. Hematite is an iron oxide mineral. It is non-magnetic and has colour variations ranging from steel silver to ...
