An ore of the metal chromium, usually the principal ore mineral is chromite
Another major groups of deposits in the mafic layered complexes are platinum group elements and chrome deposits but unlike copper nickel massive sulfides they don’t form as puddles on the floor of the intrusions they form in discrete layers well up in the magma chamber The PGE’s that’s platinum palladium, rhodium with less amounts of osmium, ruthenium and iridium are often but not .
chromium ore at implats the world chromium ore production originates from the mineral chromite (a chromium-iron oxide) in the rock or ore called chromitite the majority of the chromium mineral resources of the world are to be found in the bushveld complex of south africa and the great dyke of zimbabwe, where it occurs as

clean ore is hand sorted, while the fine clean ore is gravity separated Lumpy ore mixed with host rock may require heavy medium separation If chromite minerals occurs in fine grains intermixed with host rock, crushing, gravity separation and magnetic separation may be used 
A fundamental goal of mineralogy and petrology is the deep understanding of mineral phase relationships and the consequent spatial and temporal patterns of mineral coexistence in rocks, ore bodies .
Chromium ore is a natural mineral formation (lumpy, dark grey in colour) containing chromium in such compounds and concentrations as to make its commercial exploitation technically feasible and economically expedient The only chromium-containing minerals that provide an industrial source of chromium are the chrome spinellids
Apr 24, 2015· The ore deposits are generally composed of a main product, one or more by-products and trace elements such as zinc-lead-silver, copper-gold, chromium-nickel platinumpalladium Sometimes a single mineral forms the valuable deposit such as calcite in marble
Table of ContentsOre SamplesChromite Ore ProcessingShaker Table Concentration of Dry Crushed OreChromium Ore MetallurgyConclusions Chromium has a wide variety of applications in the modern world Its major uses are in stainless steels and the plating of metals Other important uses include alloy steel, heating elements, pigments, leather processing, catalysts, and refractori
The layers are preserved when the sedimentary rocks metamorphose to form serpentinite Referred to as chromitites, these rocks are the most important ores of chromium The weathering of chromite ore bodies can also lead to its concentration in placer deposits Name: For its CHROMium content
Note that these are broad generalities only, and that there can a wide range in concentrations within varieties of a single rock type that may not be economically significant For example, an assay of 2000 ppm nickel may seem anomalously high, but it is only background if the rock assayed is an olivine-bearing ultramafic rock
The element chromium is most abundant in chromite in the form of trivalent (Cr-III) When chromite ore is exposed to aboveground conditions, Cr-III can be converted to Cr-VI, which is the hexavalent state of chromium Cr-VI is produced from Cr-III by means of dry milling or grinding of the ore

It occurs naturally in various types of rock, soil, ore, and volcanic dust as well as in plants, animals, and humans Common Forms The most common forms of chromium in the environment are trivalent chromium (chromium-3), hexavalent chromium (chromium-6) and the metal form of chromium (chromium ,
This work was focused on the extraction of chromium from a local phosphate rock (region of Djebel Onk, north-east of Algeria) The sequential extraction of chromium has been investigated in order to determine the speciation of chromium in the phosphate ore, which gives us information about the amount of mobile chromium in the raw material
Chromite, the principle ore of the element chromium, is a commercially valuable mineral However, due to mining restrictions and the fact that Chromite is not commonly found in crystallized form, it is not well-represented in mineral collections
