Chromite Ores from Oman are mainly located in the mountainous region of Sohar, Somail and Sur. The quality of metallurgical grade chromite ores from Somail is the highest in terms of Cr2O3 content. Typical grade of metallurgical grade are shown below, with a Cr:Fe ratio of : 1 minimum. The grade from Somail region is from 32% to 42%.
Chrome ore sand for the refractory industry. In addition to ferrochrome production, chromium ore, also known as chromite, is also used in the refractory and metallurgical industries. Its resistance to fire of up to 1900 °C, good gas permeability and low thermal expansion combined with good thermal conductivity make this raw material an

Chromite is a mineral oxide to which the spinel group refers. It is one of the essential minerals for use in metallic chromium processing. Chromite is also found in stainless steels and as an alloying component in weapon steelsChromite is a commonly occurring iron oxide in
Description. Chromite is a mineral composed of natural oxide of ferrous iron and chromium, with varying amounts of magnesium and aluminum substituting for the
Chromite is an Iron chromium oxide found naturally in the earth crust. It is by far the most industrially important mineral for the production of metallic chromium, used in the production of Stainless and Tool Steel. It is also used as a refractory material because of its high heat stability.
Cummulate mineral found in ultramafic portions of layered mafic intrusions. Common in meteorites. IMA Status: Valid Species (Pre-IMA) 1845 : Locality: Bastide de la Carrade, Gassin, Var, France. Link to Location Data. Name Origin: Named after its chemical composition. Synonym: Chrome iron ore : Chromic iron : Ferrichromite - magnetic
Chromite is a black chromium-bearing mineral, FeCr 2 O 4. It is a principal ore of chromium (Cr). Chromite is a member of the spinel group. These minerals share the same structure but differ in composition. Al and Mg in the lattice of spinel are replaced by Cr and Fe, respectively. Crystals picked out of a chromite concentrate from the Rustenburg mine, Western Bushveld, South Africa. Width of
Chromite is the only commercial chromium ore. It is a mineral of the spinel group and has the ideal formula FeCr 2 O 4. Magnesium may replace iron and aluminium, and aluminium may replace chromium and therefore natural chromite is a complex mineral and has the general formula (Fe,Mg)O(Cr,Al,Fe) 2 O 3. Pure chromite contains % Cr 2 O 3 but natural chromite rarely contains more than 50% Cr
The principal uses of Chromite Ores is the making of the alloy ferro chrome. Ferro chrome. is used to manufacture Chrome, Chrome-nickel and Stainless Steels. The surge in the demand for stainless steel in the world, and especially in China, has led to a general shortage of Chromite Ore supplies.
When chromite, the mineral, is extracted from the earth's mantle, it is referred to as chrome ore. Chrome ore is crushed, screened, jigged into chrome concentrate and then smelted into ferrochrome. Ferrochrome, with nickel, is then processed into stainless steel. The processing of chromite is depicted in Figure 1. As chrome ore,

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. It has a conchoidal or an uneven fracture as well as no distinct cleavage. Crystals are small and rare. It may occur in octahedrons but it
This paper examines certain interrelational aspects between the ore gangue and chromite mineral types, the influence of the primary PGM extraction circuit and secondary chromite extraction
Chromite ore Chromite ore is the only commercial source of chromium. About 80% of world production comes from India, Iran, Pakistan, Oman, Turkey and Southern Africa (which produces half of this). In Zimbabwe, chrome occurs in two distinct geological environments; the Great Dyke and the Greenstone belts.
