Chromite The only mineral ore of chromium metal

Chromite The only mineral ore of chromium metal

Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4). It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite bearing rocks are altered by heat or weathering.

Overview. In 2011, U.S. production of chromium was estimated at 160,000 metric tons, coming almost entirely from recycling stainless steel scraps. In addition, the U.S. imported 430,000 metric tons of chromium, primarily from South Africa, Kazakhstan, Russia and China. Chromium is valued for its high corrosion resistance and hardness.
