chromite, which is the only ore for chromium, and they are the primary source for both high-chromium, low-aluminum ore, used in metallurgical applications, and high-aluminum, low-chromium ore, used in refractories (Thayer, 1946; Thayer, 1963; Dickey, 1975). Concentrations of chromite as
and trivalent metal ions, respectively. Four types of chromite ore deposits occur as either lode or secondary deposits. Lode chromite ore deposits comprise stratiform and podiform deposits, whereas secondary chromite ore deposits comprise laterite and placer deposits. Chromite is an important industrial mineral used in the refractory industry.
A new green metallurgical process for chromite ore has been proposed and developed to solve the serious environmental problem in the traditional production process of chromate.
The kinetics of reduction of chromite ore plays an important role in controlling the productivity of the processes and quality of Ferro-chromium. A considerable amount of research has been carried out on the carbothermic reduction of chromite ore to elucidate the kinetics …
Chromite ore has a spinel structure with a general formula of (Fe,Mg)O.(Cr,Al,Fe) 2 O 3. The content of Cr 2 O 3 for metallurgical-grade chromite ore is in the range 42–55% and the chromium-to-iron ratio is higher than 1.5. These quantities determine the chromium content in the smelted chromium ferroalloys.
satisfactory low-grade metallurgical chromite. Perhaps 30,000 to 50,000 tons of chromite concentrates that would range from 30 to 54 percent Cr2O3 could be obtained from placer deposits in the State Line and Soldiers Delight districts. A small tonnage of chromite remains in dumps at …
Chromite ores have been classified into metallurgical, refractory, and chemical ores (table 1) for their end-use applications by the metallurgical, refractory, and chemical industries, respectively. Metallurgical ore, which has a high Cr2O3 content and a high chromium-to-iron ratio, is desirable for making ferrochromium or ferro-silicochromium ...
Metallurgical Grade Chrome Ore Concentrate Around 92% of all the chromium produced in the world is consumed in steel, to which it brings a high resistance to corrosion, temperature and wear. The steel which uses chromium most extensively is stainless steel – stainless steel consumes more than 80% of the chromium used in steel applications.
