Chromite an overview ScienceDirect Topics
Chromite ore can be separated in a highstrength field, despite the presence of iron impurities The choice of method depends on several factors, primarily the type of the gangue In some cases, separation and dressing methods are optimized to take into account other useful elements, such as PGM (platinum group metals) in South Africa, where noble metals extraction (besides chromium) is of high importance Chromite ore dressing technology is developed to take into account mineralogical, petrographic, and physicochemical features of raw material and its components A possibility is shown for complex use of mineral resources of chromite deposits by improving the quality of oredressing wastes and intermediate products being a raw material for refractories, foundry sand, and antiburningon paintPrimary processing of chromite ores and orepreparation of Chromite ore dressing technology is developed to take into account mineralogical, petrographic, and physicochemical features of raw material and its componentsPrimary processing of chromite ores and orepreparation of Chemical grade chromite ore, used to manufacture sodium dichromate, generally has a Cr203 content of over 44%, with a Cr:Fe ratio of about 15, and a silica content of less than 35% Refractory grade chromite traditionally has low (3040%) Cr203 content, Chromite mineralogy and processing ScienceDirect The Chromite and Chrome Ore Market – Global industry Analysis, Size, Share, Growth, Trends and Forecast, 2021–2027 report provides AN analysis of the Chromite and Chrome Ore Marketplace for the period 2021–2027, whereby 2020 to 2027 is that the forecast period and 2019 is taken into account because the base year information for 2016 has been enclosed as historical info The report covers all the trends and technologies that play a serious role within the growth of the Chromite Global Chromite and Chrome Ore Market Size, Growth, Sales
Chromite mining Oregon Encyclopedia
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 The strategic mineral concept was created during World War I and became law just prior to World War II with the passage of the Strategic Minerals Act 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 chromite Chromite: The only mineral ore of chromium metal As the majority of Cr rich Indian chromite ore are friable in nature and available in fine form, utilisation of chromite fines for production of superior quality ferrochrome is essential For this purpose, in the present study, the smelting of chromite pellets, briquettes, sinter and lump ore has been carried out in an electric arc furnace of 50 kVAA comparative study for smelting of chromite ore, pellets Synchrotron microstructural analyses of chromite ore processing residue showed that up to 50% of the hexavalent chromium is bound in inaccessible, hardtodissolve mineralsMicrostructural Analyses of Cr(VI) Speciation in Chromite The ore dressing technology of chrome ore mainly has Gravity separation process, the chrome ore mining equipment are jig separator, shaking table, spiral classifier, centrifugal concentrator and spiral chute, and sometimes the concentrate will be selected by weak magnetic separator or high intensity magnetic separator to further improve the grade of chromium concentrate and the ratio of spiral chute separator for chromite ore concentrate
