  • Uses of Chromium | Supply, Demand, Production, Resources

    Chromite, the only ore of chromium, was first discovered in the United States sometime about 1808 on the farm of Isaac Tyson, Jr, just north of Baltimore, Md Scattered deposits of chromium minerals in an area of northeastern Maryland and southeastern Pennsylvania were the source of nearly all of the chromium products in the world between 1828 and 1850 Currently, the only domestic commercialChromite deposits are mined by both underground and surface techniques Much of the ore is rich enough to be used directly: for production of ferrochromium, a rich, lumpy ore containing more than 46 percent Cr 2 O 3 and having a chromiumiron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40 percent Cr 2 O 3Chromium processing | BritannicaDepending on the concentration of chromium spinelides and overall composition of chromium ore (ie, the content of Cr 2 O 3), the deposits are subdivided by way of convention into commercial and noncommercial types (Table 83) High grades might be essentially processed without or with a little dressing procedure; other types require proper dressing technologiesChromium Ore an overview | ScienceDirect Topics

    Chromium is mined as chromite (FeCr2O4) ore About 2/5ths of the chromite ores and concentrates in the world are fashioned in South Africa, while Kazakhstan, India, Russia, and Turkey are also sizeable producers Unexploited chromite deposits are plentiful, but geographically resolute in Kazakhstan and southern Africa As chromium metal elements were utilized in dyes and paints and the tanningChromium 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 chromiumcontaining minerals that provide an industrial source of chromium are the chrome spinellids In addition to chrome spinellids, the primary minerals of chromeChromium Ore Cargo Handbook the world's largestThe 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 It is mostly used for making stainless steel and other metal alloysChromium Mining | Processing Equipment | Flow Chart
