Magnetite & Lodestone | Mineral Photos, Uses, Properties

Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight.

Meteorite Museum

The major difference between iron produced by human activity and meteoritic iron is the presence of the element nickel. Iron metal in all meteorites contains at least some nickel whereas man-made metal objects generally do not. In addition, the interior structure of iron meteorites is unique and unlike any man-made metal alloys.

Ferrous vs Non-Ferrous Metals: What's the Difference?

Dec 19, 2017· Posted December 19, 2017. The textbook difference between ferrous vs non-ferrous metals is the presence of iron; ferrous metals are those made of or from iron, while non-ferrous metals are those that do not contain iron.The word ferrous is derived from the Latin ferrum, meaning "iron," and like copper and bronze, the word not only denotes a metal widely used today on an industrial and ...

Iron Ore Processing for the Blast Furnace

discharge is screened at 1/4" on trommel screens attached to the mill. Ore smaller than 1/4" is pumped in slurry solution to the wet cobber magnetic separator, which begins the process of separating the iron from the non-iron material. The magnetic iron ore is then laundered in two slurry surge tanks while the non-magnetics (silica/sand) go to the

Magnetite - University of Minnesota

Iron isn't the only element that displays magnetism.Nickel, cobalt, gadolinium, terbium, and dysprosium are also ferromagnetic. As with iron, the magnetic properties of these elements depends on their crystal structure and whether the metal is below its Curie point. α-iron, cobalt, and nickel are ferromagnetic, while γ-iron, manganese, and chromium are antiferromagnetic.
