Chromium (Cr) Ore | Minerals, Formation, Deposits

Chromite is a dark, opaque mineral with a high specific gravity and metallic luster. It is typically found in the form of euhedral crystals, irregular grains, or as interstitial material between other minerals in the host rock. Chromite is composed of chromium, iron, and oxygen, with variable amounts of magnesium, aluminum, and other elements.

Chromite mining

Chromite is used as an alloy of steel for hardening cutting tools, ordnance, and armor plate. The story of chromite in Oregon begins during the Jurassic Period, approximately 150 million years ago, when both the Klamath and Blue mountains were part of Oregon's early Coast Range. Containing Oregon's oldest rocks, those mountains share the state ...
