Four primary processes are available for smelting chromite ore to produce ferrochrome. They are: Conventional smelting process, Outokumpu process, DC Arc route, and Premus technology.Chromite ore quality is linked with both smelting process and economic benefits [4]. With the declining of high quality chromite ore, fine or sub-grade ore is Evaluation and synergy of material and energy in the smelting

Outokumpu process involves grinding and pelletizing of ore fines, followed by sintering of green pellets and preheating before smelting (Rao and Singh, 1996; Goel, 1997). According to Goel (1997), the ore and coke fines are normally wet-ground to about 35 percent under 37 micron (400 mesh) and then pelletized to approximately +15 mmChromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its Chromium processing Extraction, Uses & Applications

Pyrometallurgical processes are a primary method to recover PGMs from spent catalyst.3 In general, they can be divided into three groups: smelting, chlorination, and sintering processes. Smelting Process. The smelting process is the mostly commonly employed approach for concentrating PGMs in many companies with advanced DC arc furnace smelting technology has been applied in industry for the smelting of fine chromite ores to produce ferrochromium since the 1980s [38] based on ASEA's DC arc furnace as shown in FigThe transformation of ferrochromium smelting technologies during the

Abstract Chromite reduction by carbon dissolved in a high carbon ferrochromium alloy melt has been investigated in the temperature range 1580-1640°C using a slag system based on CaO2-FeO-Cr2O3-SiO2-Al2O3. Although the reduction is essentially first order with respect to Cr2O3 concentration, it exhibits both zero order and The low-grade siliceous chromite ore from Ghutrigaon, Odisha, India, containing ~ 16% Cr2O3, with Cr/Fe ratio of 1.97 and ~ 55% of SiO2, does not find any use in metallurgical industry and hence(PDF) EFFECT OF CHROME ORE QUALITY ON
