Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...
Magnetite may be the most important ore of iron. It is found at Kiruna, Sweden, and in other regions of ancient and metamorphic rocks. It (rarely) forms beautiful shiny black octahedral crystals, as well as rhombododecahedrons. It is hard, 5.5-6/5 and rather heavy, d = 5.18 g/cc. It dissolves in hydrochloric acid, and, of course, is strongly ...

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 tailings disposal area.
Hematite is colored black to steel or silver-gray, brown to reddish brown, or red. It is mined as the main ore of iron.Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite). While the forms of hematite vary, they all have a rust-red streak.
10000 To 15000 Gauss Industrial Magnet Magnetic Roller Separator ... 10000 to 15000 gauss industrial magnet magnetic roller separator for tin ore/coltan ore mining plant is widely used for separation of Iron , magnetite, hematite...
Iron ore concentrate recovery is based on magnetic beneficiating methods. The ultra pure iron concentrate is widely used in steelmaking, metallurgy, chemistry, powder metallurgy, magnetic materials, food conservation, environmental protection, medical treatment, etc.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
This iron ore used to make pig iron from which steel is made. Mineral of the Month: February 2015. Magnetite– Fe 3 O 4 – (māg’nĭ-tīt’)- Iron ore that is naturally magnetic. Magnetite is the most magnetic of all the naturally occurring minerals on Earth.
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.
By far, the two most economically important iron ores are hematite and magnetite. Although hematite is more abundant than magnetite, magnetite has the higher iron content, so magnetite iron ore deposits are highly sought after.
Magnetite ore requires complex processing to separate magnetite minerals from other minerals in the ore to produce an almost pure magnetite concentrate with an iron content of between 68% Fe and 70% Fe that is highly sought after by steel makers.
Magnetite can be added as a very fine powder to the plastic mix to increase the weight. Magnetite is an excellent source of iron for the production of iron-based chemicals like ferric chloride and ferric sulphate, that are used as alternatives to aluminum hydroxide.
Magnetite crystals and magnetite mineral specimens at mineralminers.com: your on-line link direct to the natural iron ore mines for specimens of natural magnetic lodestone, massive magnetite iron ore available in bulk, and natural magnetite octahedrons in matrix.
Examples include iron (III) oxide (Fe 2 O 3), used as the magnetic material in things like cassette tapes and computer hard drives and also as a paint pigment; and iron (III) chloride (FeCl 3), used to manufacture many industrial chemicals.

No. The concentration of low-grade magnetic iron ores, separating the magnetite crystals from the . Mr. Ball made the magnets, a small machine was built (shown in Fig. This, I think, was the first use of magnetic iron-ore ...
Magnetite is the most magnetic mineral. High iron content gives magnetite its opaqueness and black color. Spinel which shares the same structure is variably colored and transparent because it contains magnesium and aluminum instead or iron. Magnetite is dense (specific gravity 5.20) mineral.

Uses of Hematite (Iron Ore) Hematite is the world’s most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world.
Magnetic Iron Ore Resources. A thorough examination of some of the iron-ore properties and the knowledge acquired by development of extensive underground workings makes it possible to make quite definite estimates of tonnage available in certain areas, which show very large reserves.
This chapter introduces the principle of how low-grade iron ores are upgraded to high-quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth, so low-intensity magnetic separators are used to upgrade magnetite ores.
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.
Magnetite ore is a ferromagnetic material, with the chemical formula Fe3O4, and is one of several types of iron oxide. It is a ubiquitous mineral in many parts of the world, including Australia, the USA, Canada, South Africa, Mozambique and many other countries across most of the world's continents.
Other minerals, such as magnetite, contain higher concentrations of iron, but hematite is so much more abundant that it is the most economically important iron ore. In North America, over 90% of our iron comes from hematite deposits and without hematite our steel-based society could not exist.
