The use of chromium for the production of refractories is the result of the high melting point (2040 °C) and the chemical inertness of chromite. Chromite is, therefore, useful in the production of refractory bricks, and mortars used in high-temperature furnaces [2]. The chemical industry produces more than 70 different chromium compounds for ...

Chromite and chromium are especially toxic to humans. Because of this, the process of mining chromite must be done very carefully. The iron-chromium alloys produce pollutants and dust, causing health risks to the environment and miners. It is important that geoscientists and energy corporations alike take these risks into account when mining ...

Composition of chromite in a given deposit is now a preferred method of classification, such as high-chromium, high-lron, or high-aluminium [3]. High-chromium ores, with high Cr-Fe ratios are used mainly to produce ferrochromium, an essential alloying element in stainless, heat-resistant, hlgh-strength and oxidatlon-resistant steels.

Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr2O4). It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat …

The principal producing areas of chromite are South Africa, Russia, Albania, the Philippines, Zimbabwe, Turkey, Brazil, India, …

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 …

Chromite, an oxide of iron, magnesium, aluminum, and chromium, is the only ore mineral of chromium. In nature, chromite deposits are generally of two major types: stratiform (layered) and podiform (pod shaped). Both …

Chromite and chromium are especially toxic to humans. Because of this, the process of mining chromite must be done very carefully. The iron-chromium alloys produce …

The ICDA reports world production of chromite by end-use sector and categorizes it as chemical, foundry sand, metallurgical, and refractory (Papp and Lipin, 2006). According …

Domestic Production and Use: In 2023, the United States consumed an estimated 4% of world chromite ore production in various forms of imported materials, such as chromite …

Taganito HPAL Nickel Corporation (THPAL), a mineral processing plant and a subsidiary of Sumitomo Metal Mining Co., Ltd (SMM), officially started its commercial operation of chromite last March 2021 to produce chromite concentrate. The company decided to commercially extract chromite to be used primarily as a raw material for …

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.

The first patent for the use of Cr in steel was granted in 1865, although the large-scale employment of Cr did not occur until the early 1900s when the electric arc furnace started widely being used and could smelt chromite into the master alloy (alloy was used as a feedstock to produce other alloys). Chromite Producing Countries.

(a) Chromite ore. Chromite ore consists of varying percentages of chromium, iron, aluminium and magnesium oxides as the major components. It has been classified into three general grades associated with their use and chromic oxide content: metallurgical (greater than 46%), chemical (40–46%) and refractory (less than 40%) grades ().During …

Chromite. Chromite, a brownish black cubic mineral belonging to the spinel group, is the only ore mineral from which metallic chromium and chromium compounds are obtained. It has the chemical formula FeCr 2 O 4, and a theoretical composition of 32.0% FeO and 68.0% Cr 2 O 3. In its natural form it occurs in solid solution with other minerals in ...

chromite ore from the Ruighoek chromite deposit located in the western sector of the Bushveld Complex [7,8]. The aims of the study were to fully characterize the chromite ore using bulk assays, X-ray diffraction, and optical and automated electron beam micro-analysis techniques, and to use the mineralogical data to provide input into the …

Pre-reduction of chromite ore is crucial for producing ferrochromium alloy by submerged arc furnace (SAF) smelting. In this study, an efficient method for low-temperature pre-reduction of chromite ore using biochar under microwave irradiation was explored to produce good burden for subsequent SAF smelting. The thermodynamic …

The chromium (Cr) content of stainless steel originates from recycled scrap and/or ferrochrome (FeCr), which is mainly produced by the carbothermic reduction of chromite ore. Ever-increasing pressure on FeCr producers to curtail carbon emissions justifies migration from traditional FeCr production routes. The interaction between …

But grinding will produce a large amount of ore slime. If a cationic collector is used to extract chromite in the alkaline slurry, it needs to be deslimed in advance, but the fine sludge removed will take away a lot of chromite. The use of an anionic collector in alkaline slurry can save the pre-desliming.
