how is chromite used in the world

Chromite Earth Sciences Museum University of

Chromite. Chromite is the main source of the metal chromium, a metal used to induce hardness, toughness and chemical resistance in steel. It was named after its chemical composition, chromium oxide. The mineral is brownish to black in colour with a dark brown streak.

Uses of Chromium Supply, Demand, Production, Resources

The world's largest stratiform chromite deposits are found in South Africa, in what is known as the Bushveld complex. This is a layered igneous intrusion containing more than 11 billion metric tons of chromite resources. Podiform deposits are found in layered igneous sequences that developed in oceanic crust below the sea floor.

Chromite - an overview ScienceDirect Topics

Chromite mining in Turkey started in 1850; since then, Turkey has had an important role in the world chromite market. Turkey produces chromite ore and ferrochrome. It is estimated that Turkey has produced about 45 metric tons of chrome ore. Chromite production is mainly export-oriented. Turkey has one chrome and two ferrochrome chemical plants.
