Chromite is an iron chromium oxide commonly associated with olivine, magnetite, serpentine, and corundum. As a major source of metal chromium, the extracted chromium from chromite is used in chrome plating and alloying for production of corrosion resistant superalloys, nichrome and
Chromite, relatively hard, metallic, black oxide mineral of chromium and iron (FeCr 2 O 4) that is the chief commercial source of chromium. It is the principal member of the spinel series of chromium oxides the other naturally occurring member is magnesiochromite, oxide of
The Chromite Extraction Flowsheet Chromite Ore Crushing The crushing section for this 250 ton per day chrome mill consists of a coarse ore grizzly, a coarse ore bin with pan feeder to a 1''8″ reduction crusher and a crusher discharge conveyor to a crushed ore bin.
Chromite is the most important ore of chromium from which it derives its name. Chromium is an important metal and has a wide range of industrial uses. Chromite forms in deep ultramafic magmas and is one of the first minerals to crystallize.
In this study, we present a systematic study of major and trace element compositions of chromite in chromitite in the PozantıKarsantı ophiolite, southern Turkey. These data, together with mineral inclusions in chromite, are used to constrain the origin and nature of parental magmas from which chromitite formed.
What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromitebearing rocks are altered by heat or weathering.
Chromite definition is a black mineral that consists of an oxide of iron and chromium and is the only chromium ore.
When the chromite mineral occurs in fine grains intermixed with other minerals, crushing may be used in conjunction with gravity separation and magnetic separation.

Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world''s chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.
Sun Metals is a mineral exploration company focused on advancing its flagship Stardust project loed in central British Columbia, Canada. Stardust is a polymetallic Carbonate Replacement Deposit with a rich history. Sun Metals believes British Columbia is a reliable jurisdiction with excellent exposure to capital markets, a deep pool of
Occurrence: A cumulus mineral in ultramafic portions oflayered mafic igneous rocks an accessory mineral in alpinetype peridotites also detrital. Common in all meteorites, except carbonaceous chondrites, and in lunar mare basalts. Association: Olivine, enstatite, plagioclase, serpentine, magnetite, ilmenite, pyrrhotite, pentlandite, ulvospinel.
Chromite The only ore of chromium, chromite is a major constituent in stainless steel. It is one of the first minerals to separate from a cooling magma, and large chromite deposits are thought to have been derived by such magmatic differentiation.

Chromite with pen for scale. From the mineral collection of Brigham Young University Department of Geology, Provo, Utah, courtesy of the U.S. Geological Survey Denver Library Photographic Collection.
Chromite, a mineral ore that is mined from crystallized magma, is used in the production of steel as a pigment and as a alyst in many chemical reactions.
Chromite, a brownish black cubic mineral belonging to the spinel group, is the only ore mineral from which metallic chromium and chromium compounds are obtained. It has the chemical formula FeCr 2 O 4, and a theoretical composition of 32.0% FeO and 68.0% Cr 2 O 3 .
Chromite is a common and widespread mineral that occurs in the ultramafic layers of layered igneous intrusions, as an accessory mineral in Alpinetype peridotites, as a detrital mineral
Chromite contains Mg, ferric iron [Fe(III)], Al and trace amounts of Ti. Chromite can change into different minerals based on the amounts of each element in the mineral. Chromite is a part of the spinel group, which means that it is able to form a complete solid solution series with other members in the
Chromite is a mineral that contains chromium. It is considered a strategic mineral, which generally means that it is necessary for military and industrial use during periods of national emergency.
Chromite Chromite, an oxide mineral, is the major ore of chromium. It is often used for the bricks and linings of blast furnaces as it can withstand very high temperatures.
Define chromite. chromite synonyms, chromite pronunciation, chromite translation, English dictionary definition of chromite. n. A widely distributed black to brownishblack chromium ore, FeCr2O4. n 1. a brownishblack mineral consisting of a ferrous chromic oxide in cubic Chromite definition of chromite by The Free Dictionary.
Crocoite is a mineral consisting of lead chromate, Pb Cr O 4, and crystallizing in the monoclinic crystal system. It is identical in composition with the artificial product chrome yellow used as a paint pigment.
Chromite is the sole source of the metal chromium, which is the chromeiron alloy employed in the manufacture of special grades of steel. Chromium salts are used in tanning and as pigments and plating.
Foundry sand use of chromite is a modern appliion. Sand is used to contain molten metal in a desired shape until the metal has solidified. Sand used in the foundry industry is washed, graded, and dried. Since silica sand is common and inexpensive, it is the most commonly used mineral.
The stannous chloride reduces the Fe+3 to the Fe+2 form necessary for the titration. Interfering elements that are reducible by stannous chloride are rare in chromite mineral samples and ferrochrome slags. The excess stannous chloride protects the Fe+2 from air oxidation while cooling.

Chromite, an oxide of iron, magnesium, aluminum, and chromium, is the only ore mineral of chromium. In nature, chromite deposits are generally of two major types: stratiform (layered) and podiform (pod shaped). Both types are associated with ultramafic igneous rocks. The world''s largest stratiform chromite deposits are found in South Africa, in
With low electricity prices, South Africa has been able to expand chromite and ferrochrome production more or less continuously since the AOD process was developed in the 1960s to use ferrochrome smelted from lowergrade ores. Samancor was created in
Chromite Rich, solid granular or crystalline aggregate of black Chromite ore. Though not producing Chromite ore, this large 30 mile complex of layer igneus mafic rock currently does not produce chromium ore. It is currently mined for its platinum and palladium only. Ore specimens are hard to obtain. Widely used in chemicals, metals and refractory materials.
