GeologyIntroductionCausesFormationSignificanceResourcesExamplesOne of only a few naturally occurring magnetic materials, magnetite fascinated early civilizations and set many on a path toward the modern compass. Consequently open sea navigation, commerce and warfare are to a great degree part of magnetites legacy. A relatively common, black, metallic mineral, magnetite is also one of modern societys most important iron ores, occurring in a variety of igneous rocks, pegmatites, contact metamorphic rocks and hydrothermal veins. In our modern Earth, magnetite seldom forms in se

how is magnetite used - zomerfeest-lorentzschool

Magnetite as a mineral has a wide variety of uses right from serving as magnetic decor to keeping trains from moving off track. One of the most significant uses of magnetite lies in its iron ore status and its industrial importance in manufacturing steel. Magnetite is also an important component of power plants and is used to generate electricity.

SignificancePropertiesGeologyUseProductionOther usesFormationScopeMagnetite is a very common iron oxide (Fe3O4) mineral that is found in igneous, metamorphic, and sedimentary rocks. It is the most commonly mined ore of iron. It is also the mineral with the highest iron content (72.4%).

How iron is made - material, manufacture, making,

BackgroundHistoryThe Manufacturing ProcessQuality ControlByproducts/WasteThe FutureIron is one of the most common elements on earth. Nearly every construction of man contains at least a little iron. It is also one of the oldest metals and was first fashioned into useful and ornamental objects at least 3,500 years ago. Pure iron is a soft, grayish-white metal. Although iron is a common element, pure iron is almost never found in nature. The only pure iron known to exist naturally comes from fallen meteorites. Most iron is found in minerals formed by the combination of iron w

How magnet is made - material, manufacture, making

Various steel alloys can also be magnetized. The first big step in developing more effective permanent magnet materials came in the 1930s with the development of Alnico alloy magnets. These magnets take their name from the chemical symbols for the aluminum-nickel-cobalt elements used to make the alloy.

Iron and steel - Introduction to their science,

The steel you probably see most often is stainless steel—used in household cutlery, scissors, and medical instruments. Stainless steels contain a high proportion of chromium and nickel, are very resistant to corrosion and other chemical reactions, and are easy to clean, polish, and sterilize. They're corrosion-proof because the chromium atoms

2016-8-29  In this , we investigated the effects of surface roughness and agitation on the morphology of magnetite films electrodeposited from alkaline Fe(III)-triethanolamine (TEA) solutions on carbon steel substrates. The surface roughness of the carbon steel substrates was maintained in the range of 1.640.06 μm by using mechanical grinding and polishing methods.
