The present invention relates to a process for simultaneous recovery of chromium and iron from Chromite Ore Processing Residue (COPR) and more particularly, the present invention relates to an economical and environmentfriendly process for recovering chromium as a chromate salt and iron as an iron salt from nonleachable Chromite Ore Processing Residue and avoids landfilling of toxic metals.
Ferrochrome, or Ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy between chromium and iron, generally containing 50% to 70% chromium by weight.. Ferrochrome is produced by electric arc carbothermic reduction of of the world's ferrochrome is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.
Like mining, beneficiation (processing, crushing, separating, smelting, refining, etc.) for chromite depends on the characteristics of the ore deposit and on the mining methods used. For example, an operation extracting only highgrade ore may require only hand sorting and screening.

Chromite ore processing begins in Hudson County. With its proximity to one of America's busiest ports, Hudson County becomes a center for chrome production because most of the world's chrome reserves are located outside the United States.
Chromite ore is prepared for processing using several methods, depending on the ore source and the end use requirements. Course clean ore is hand sorted, while fine clean ore is gravity separated. Lumpy ore mixed with host rock may require heavymedia separation. If the chromite mineral occurs in fine grains intermixed with host rock, crushing,
