2 #0183;#32;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.
Chromium is a chemical element that is denoted by the symbol Cr and its atomic number is 24. It is a steelgray, radiant, hard metal that show cases a high polished surface and has a high end melting point. It is also odorless, bland, and pliable.

Stoping process only occurs in underground mineral mining where the surrounding rock is hard enough to permit the extraction process. High concentration of the ore is rich enough to be used directly for the production of ferrochromium, a rich and a lumpy ore containing a very high percentage of Cr2O3.
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
