Production takes place primarily in countries with substantial chromite ore supply. Relatively cheap electricity and reductants also contribute to the viability of high The energy-intensive carbothermic smelting of chromite ore yields ferrochrome (FeCr)—a crude alloy of Cr and Fe [ 3, 4, 5 ].

Two types of sinter with the best performance—the best sintering rate, strength, and product yield—are studied. It is demonstrated by experimental melts that In recent years, FeCr producers have been pressured to curve carbon emissions, necessitating the exploration of alternative smelting methods.

Ores. Although chromium occurs in many minerals, the only ore exploited commercially is chromite.This spinel mineral is ideally composed of ferrous oxide and chromic oxide with the chemical composition FeO Cr 2 O 3, but it is often found in nature with magnesia (MgO) substituting for FeO and alumina (A1 2 O 3) or ferric oxide (Fe 2 O 3) substituting for Cr 2 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.

Chromite, the only commercial source of chromium, is a spinel group mineral that occurs in ultramafic igneous rocks and further 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 olivine. In addition, it is also found in metamorphic rocks A chromite occurrence called the Sabantuy paleoplacer was discovered in the Southern Pre-Ural region, at the east edge of the East-European Platform in the transitional zone to the Ural Foredeep. A ca. 1 m-thick chromite-bearing horizon is traced at a depth of 0.7–1.5 m from the earth’s surface for the area of ca. 15,000 m 2.Special Issue "Chromite Deposits: Mineralogy, Petrology and

Mintek has applied DC arc furnace technology to the reductive smelting of numerous materials over more than three decades. The first industrial implementation of this technology was for the smelting of chromite fines to produce ferrochromium in 1984.

The raw material in the production of ferrochrome is chromite, which is chrome and iron oxides containing mineral. Chromite is used as lumpy ores or fine con centrates, which must be generally agglomerated to make them useable charge for the furnace. Fines in the smelting furnace cause unbalanced operation and thus de-crease SiO2 as flux and CaO as slag modifier in chromite smelting. Colemanite can be approximated by the formula 2CaO.3B 2 O 3 .5H 2 O. Crystal water is released from pureFluxing of South African chromite ore with colemanite
