Chromite
Basic Information. Chromite is a dark grey, metallic, oxide mineral. Due to its metallic luster and occasional magnetic properties, chromite is often mistaken for magnetite. Chromite can often be found in basic igneous rocks, and in the metamorphic and sedimentary rocks created by rocks containing chromite that were affected by weather.
KPMG commodity insights bulletin chromite
Chromite. Chromite is the commercial name of iron chromium oxide (FeCr2O4), a mineral comprised of chromium and iron oxide that is naturally found in the earth's mantle. When extracted, it is referred to as chrome ore. Chromite is crucial for the production of ferrochrome, an alloying agent in manufacturing stainless steel.
Chrome ore
Chrome ore is the common name for the mineral chromite, which is described in the technical literature as an iron chromium oxide. The most important applications of chromium ores are in the manufacture of stainless steel, gray cast iron, iron-free high-temperature alloys, and chromium plating for surface protection.
