chromium processing Britannica

When chromite and lime are melted in an open electric-arc furnace and then contacted with ferrochrome silicon, a low-carbon (0.05 percent) ferrochromium can be obtained. In an alternate process, high-carbon ferrochromium is oxidized and then blended with additional high-carbon ferrochromium.

Chromite- mineralogy and processing ScienceDirect

Jan 01, 1988High- iron chromite, previously used to manufacture chemicals, is now increasingly being used in stainless steel manufacture, the introduction of the Argon Oxygen Decarburisation (AOD) process having resulted in the Cr:Fe ratio being less critical. High-iron ores are also being used as foundry sands, and for refractory purposes.

Efficient immobilization and utilization of chromite ore

Chromite ore processing residue (COPR) has been a severe environmental contaminant which is worthy of attention. In this study, we developed an eco-friendly and practical technology for effectively stabilizing and recovering Cr(VI) in COPR via combining FeSO 4 reducing agent and the hydrothermal treatment. A stable spinel phase product was formed during detoxification.

Uses of Chromium Supply, Demand, Production, Resources

Chromite is used in high-temperature applications, such as blast furnaces and molds for firing bricks, because it retains strength at high temperature. Chromium is also vital for good health. Insufficient amounts result in glucose intolerance in humans. Organ meats, mushrooms, wheat germ, and broccoli are all good dietary sources of chromium.

Chromite-Manufacturing Technology, Applications, Patent

The processing of chromite ore is associated with the generation of large quantities of solid wastes containing chromium, which have been disposed of as landfill for many years. The mobilization and operational speciation of chromium contained in soils contaminated with metal salts are important in terms of the environment.

Chromite Beneficiation Process

Apr 12, 2016Chromite Process Summary. This flowsheet is very effective due to the ability to remove the high grade chrome with very little grinding on each pass through the mill. In this way, grinding takes place with a large number of small reductions followed by immediate removal of the liberated chrome into a high grade concentrate.
