Introduction The mineral chromite is the only ore of chromium. Chromium is very important for industries in the present day. It is used to produce stainless steel, and other nonferrous alloys, to enhance their harden ability and to make these allows more resistant to corrosion and oxidation. Chromium is used in the plating of metals, pigments, leather processing, catalysts, surface treatments, and refractory. Chromite is an iron chromium oxide, FeCr 2 O 4 . In some samples, magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite, MgCr 2 O 4 . Chromite has high melting point and a stable crystalline structure. The purpose of this experiment is to determine the chemical content of a metal ore sample though to be mineral chromite. There is one way that we can perform this experiment, Hydrometallurgy, which is a form of extractive metallurgy that utilizes aqueous solution chemistry for the recovery of metal form salts, minerals, and ores. It is typically divided into
