Although chromium is a metal, it does not occur naturally in metallic form. Chromium can be found in many minerals, but the only economically significant chromium-bearing mineral is chromite. Chromite has been mined from four different deposit types stratiform chromite, podiform chromite, placer chromite, and laterite deposits. Most of the worlds resources, however, are located in stratiform ...
