Chromium Cr is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the worlds 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.
Aug 05, 2017 The Stillwater Complex in Montana mainly the Benbow and Mouat deposits contains an estimated 15.7 million short tons of ore containing 1.3 million short tons of recoverable chromium.This represents approximately 75 percent of available domestic chromite and could supply U.S. needs for about 4 to 5 years, but it is low in grade and has a low chrome-to-iron ratio.

Jul 20, 2017 The average grade of the metallurgical chromite ore was 43.4 pct Cr2O3, with 52 pct of the ore having a chromium-to-iron ratio of 31 or over, 17.6 pct having a ratio between 21 and 31, and 30.4 pct having a ratio less than 21. Chemical-grade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromium-to-iron ratio of 1.51 to 21.
The critical need for chrome ore in the United States has greatly increased the U. S. Geological Survey projects for locating new de posits of ore and for the study and delineation of known deposits. To cope with an increased demand for complete chemical analyses of chromite, the Survey instituted a program aimed at increasing the ...

mine produces 3 grades of chrome ore, namely lumps, chips, and concentrates. The lumps and chips of chrome ores are used as raw material and are directly fed in submerged arc furnace, while the concentrates of chrome ore must undergo agglomerating treatment, such as sintering or pelletizing. Due . Chrome Ores on Ferrochrome Smelting
When the grade of the chromite was low, mills were needed to concentrate the ore miners often converted mills used for gold. During World War I and World War II, Oregons contribution to the domestic production of chromite varied from one-fifth to one-quarter.

Chrome sand is a major component in refractory bricks that are used in the foundry industry to line furnaces, fireplaces, kilns, ovens, and other high-heat environments. The bricks must be able to withstand temperatures over 1700 C, have excellent thermal shock resistance, and have both acid and basic slag erosion resistance.

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 ultra-mafic magmas and is one of the first minerals to crystallize. It is because of this fact that Chromite is found in some concentrated ore bodies.
Both grades comfortably meet the normal specifications for South African metallurgical chrome ore concentrate, and are produced by reprocessing used high-grade foundry sand from foundries. Typical specifications for Clover Alloys two grades of metallurgical chrome ore concentrate are as follows
