Despite China's modest chromium ore reserves, over half have more than 45wt% Cr 2 O 3 content, indicating high-quality ophiolite-related ore. The Luobusha deposit, for example, has a Cr 2 O 3 grade exceeding 50%, with a (Cr 2 O 3)/(FeO) mass ratio of over 4, similar to the renowned Kempirsai deposit in Kazakhstan.

The four photos below (9.59 through 9.62) show gemmy examples of emerald, aquamarine, heliodor, and morganite that could be cut to make colorful gemstones. Although common beryl has no value as a gem, it is sometimes mined as a beryllium ore mineral. Other photos of gemmy beryl were seen in Figures 1.12, 1.13, and 1.14 (Chapter 1).
Occurrence, uses, and properties. Chromium is a relatively abundant element in Earth's crust; the free metal is never found in nature. Most ores consist of the mineral chromite, the ideal formula of which is FeCr 2 O 4.It is widely dispersed in natural deposits, which are usually contaminated with oxygen, magnesium, aluminum, and silica; their chromium content …
Chromite is the main ore of the element chromium. There are not many occurrences of collectible Chromite specimens, as this mineral mostly occurs in microcrystalline or crudely crystallized …
hromite is the single commercially viable ore of chromium (Cr) which is chemically known as iron chromium oxide (FeCr 2 O 4). The properties of chromium that make it most versatile and indispensable are its resistance to corrosion, oxidation, wear & galling and enhancement of hardenability. Chromium is an important alloying metal
Below we review the information about the high-pressure chromium-bearing phases in the Earth's mantle. Since chromite (Fe,Mg)(Cr,Al) 2 O 4 containing up to ~55 wt% Cr 2 O 3 is the major ore mineral of chromium and is an accessory phase in many ultramafic rocks, the largest chromite deposits and the models of their formation are considered.
Because chromium is unstable in oxygen, it forms an impermeable oxide layer that protects the metal beneath. Read about: Energy Resources. Chromium Ore Uses. Chromium ore is processed to produce metallic chromium, which is then used in various applications, including: It is an important part of stainless steel, making it strong and resistant to ...

Chromium ore occurs exclusively in rocks formed by the intrusion and solidification of molten lava or magma which is very rich in the heavy, iron containing minerals such as pyroxenes and olivines. The chromium spinel is a heavy mineral and it concentrates through gravity separation from most of the other molten material in the magma during ...
Elemental chromium (Cr) does not occur in nature but is present in ores, primarily as chromite (FeOCr 2 O 3). Around 90% of the mined chromite ore is converted into different grades of ferrochrome, while about 80% ferrochrome produced of mainly high-carbon or charged chrome grade are consumed by stainless steel industry. Chromium imparts to ...
Chromium. Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world's chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.
