Introduction. World supplies and reserves of chromite or chrome ore (FeCr 2 O 4) have been dominated mainly by South Africa and the former-USSR, which made chromite a strategic material in many Western countries 1.Bhappu highlighted the need for more research into the processing of low-grade refractory ores of strategic metals such as …

In this study, the liquid-phase oxidation process of chromite ore in 50 wt% KOH solution was investigated, and it was found out that chromite ore could be …

Chromite ore is the primary source of chromium. India has large reserves of chromite which is about 344.016 million tons. Orissa alone accounts for 330.714 million tons and most of it is located in

The chromite deposits in the John Day area of Oregon comprise one of the largest reserves of domestic chromite, containing over 200,000 tons of ore at an average grade of 22 percent Cr2O3 (chromic oxide). Considerable exploration and utilization research have been carried out on these deposits.

Chromite values from ultra-fine tailings of chrome ore beneficiation plant can be recovered by optimum combination of process parameters of spiral concentrator. The …

Percentage chromium oxide is improved upto 49% with 63% of recovery while raw chromite ore contained only 34.2% Cr2O3. Author concluded that separating the materials into size fraction without ...

To optimally exploit this valuable and strategic raw material, numerous chrome ore beneficiation plants have been established. Most of these plants suffer chromite losses into the tailing. Decreasing these losses would not only improve the plant performance but also make the economics of the operations more attractive.

The chromite content varied in the different size fractions and is listed in table 4. Chromite gram analyses ranged from 60 to 70 pct Cr2O3. Liberation was measured by grain counting and was performed on all the size fractions. This ore began to show chromite liberation around 20 mesh and was nearly liberated at 65 mesh.

Abstract The depletion of high-grade ores has forced the utilization of low-grade ores. The small liberation sizes in the low-grade ores require fine grinding which is an energy intensive operation. In the present study, low-grade chromite ore bearing platinum group of elements (PGE) was used as an experimental material. The previous study …

Abstract. In this investigation, we optimize the grinding circuit of a typical chromite beneficiation plant in India. The run-of-mine ore is reduced to a particle size of less than 1 mm in the ...

A new approach using sulfuric acid leaching for chromium oxide preparation from chromite was studied in this paper, in which recovered Cr 2 O 7 2 − -bearing leachate obtained from a COPR remediation process was used as an oxidant. An Eh-pH diagram of Cr–Fe–H 2 O at 160 °C was produced and experiments using chromite lumps and …

India has limited resources of chromite. To optimally exploit this valuable and strategic raw material, numerous chrome ore beneficiation plants have been established. Most of these plants suffer chromite losses into the tailing. Decreasing these losses would not only improve the plant performance but also make the economics of the operations …

Chromium (Cr) ore refers to a natural mineral deposit that contains chromium in its raw form. Chromium is a chemical element with the symbol Cr and atomic number 24. It is a hard, lustrous, and corrosion-resistant metal that is widely used in various industrial applications due to its unique properties.

Chromite Grinding. The 36″x 8′ Adjustable Stroke Ore Feeder is used to accurately control feed of crushed ore to the grinding section.

Deslimed chromite ore was floated at pH 1.5 to 5.5 using a long-chain fatty-acid collector and soluble fluoride ions as a silicate depressant. The Havens method was later modified slightly to permit flotation without preliminary desliming. This was done by preconditioning the pulp with fuel oil and fluoride ion.
