Chromite: The only mineral ore of chromium metal
Chromite is found in beach sands derived from the weathering of chromite-bearing rocks and laterite soils that developed over peridotite. Beach sand rich in chromite and other heavy minerals is sometimes mined, processed to remove heavy minerals, and returned to the environment.

Chromite Ore an overview | ScienceDirect Topics
Chromite ore has a spinel structure with a general formula of (Fe,Mg)O.(Cr,Al,Fe) 2 O 3.The content of Cr 2 O 3 for metallurgical-grade chromite ore is in the range 42–55% and the chromium-to-iron ratio is higher than 1.5. These quantities determine the chromium content in the smelted chromium ferroalloys. Magnesium oxide and alumina are refractory at the smelting temperature and fluxed with

Chromite: Mineral information, data and localities.
"Chromite" is commonly used for any Cr-rich mineral of the spinel group, particularly for the chromite-magnesiochromite series, and much of the mineral referred to as "chromite" in geological and petrological papers and mining statistics is magnesiochromite. The Fe-dominant species chromite itself can be FOUND, although uncommonly, in many

The bulk of chromite reserves are found in stratiform deposits (thin, even layers covering a broad area), but podiform deposits (scattered pod-shaped formations of varying size) are also important. Mining and concentrating. Chromite deposits are mined by both underground and surface techniques.
Sukinda has an abundance of chromite, around 97% of India's total deposits. The valley is abundant in the deposits of chromite and has the largest open cast chromite ore mines in the world. Around 12 mines operate in the area without proper environmental controls, and pollution caused by the mines is a major health hazard.
Mining | Shetland Amenity Trust
Numerous pits were dug between the 1870s and 1920s to extract chromite (iron chromate), which was initially used as a pigment and later for steel manufacture. One of these chromite mines was the largest in Britain. Its site, at Hagdale, contains the remains of a horse drawn chromite crushing circle which has recently been restored. It is the
