How is chromite ore important to society?

Chromite is important because it is the only economic ore of chromium, an essential element for a wide variety of metal, chemical, and manufactured products. Many other minerals contain chromium, but none of them are found in deposits that can be economically mined to produce chromium.

Where is chromite found?

Chromite ore is mined in over 20 countries, but about 80\% of production originates from four countries: South Africa, India, Kazakhstan, and Turkey (Kleynhans et al., 2012). Figure 11.2. Map of locations, geological types, and size (millions of tons of Cr) of global chromite resources and reserves.

What is the origin of ore?

Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. Minerals of interest are generally oxides, sulfides, silicates, or native metals such as copper or gold. Ores must be processed to extract the elements of interest from the waste rock.

How is chromite formed?

Chromite is used as a refractory in the production of steel, copper, glass and cement. Chromite occurs as a primary accessory mineral in basic and ultrabasic igneous rocks. Economic deposits form by crystallisation of chromite from a cooling magma, resulting in large stratiform deposits or smaller pod-like deposits.

How is chromite found in nature?

Chromite is found as orthocumulate lenses in peridotite from the Earth’s mantle. It also occurs in layered, ultramafic intrusive rocks. In addition, it is found in metamorphic rocks such as some serpentinites. Ore deposits of chromite form as early magmatic differentiates.

How was chromite discovered?

In 1798 a German chemist named Tassaert discovered chromium in chromite ore in a small deposit in the Var region of South-Eastern France. Chromite forms in deep ultra-mafic magmas and is one of the first minerals to crystallize from cooling magma.

What is chromite ore used for?
