Cited by 24Chromite, 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

Chromite ore processing residue (COPR) is a waste byproduct of chromate production that contains high levels of hexavalent chromium (Cr[VI]). Although the high temperature chromite process was banned in several countries, its legacy still exists at numerous contaminated sites. For instance, New Jersey alone has over 2 million tons of waste COPR.

Soon, Tyson owned mineral rights on all the orebearing sites in Pennsylvania, Virginia and Maryland. As the Siberian deposits waned, his company enjoyed a growing international monopoly in chromium ore. However, when chromium was discovered in Turkey in 1848, Tyson lost his monopoly.
