Like vanadium, chromium hardens steel, so it is frequently used in alloys, especially stainless steel. Chromium compounds are all strongly colored, and this characteristic gives chromium its name. Chromium compounds are used as a yellow coloring agent in the textiles industry. It also is used in the tanning of leather.

Chromium (Cr) has a wide range of uses in metals, chemicals, and refractories. It is one of the Nation's most important strategic and critical materials. Chromium use in iron, steel, and nonferrous alloys enhances hardenability and resistance to corrosion and oxidation. The use of chromium to produce stainless steel and nonferrous alloys are two of its more important
The element chromium is most abundant in chromite in the form of trivalent (Cr-III). When chromite ore is exposed to aboveground conditions, Cr-III can be converted to Cr-VI, which is the hexavalent state of chromium. Cr-VI is produced from Cr-III by means of dry milling or grinding of the ore.
Chromium is a fairly common ore found in the Crystal Cavern at 50 blocks (layer 3) down. Its base value is 7,000, and requires the Power Drill to mine.
Because surface mining typically is less expensive than underground mining, it is preferred, but not always possible. 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.
