Smelting Process of Chromite Ore Fines to Produce Crude

The smelting behavior of waste chromite ore fines containing Cr and Ni to produce crude Fe–Cr–Ni–N alloy was investigated in this study. In the experiments, for each heat, liquid steel melt

Technology Innovations in the Smelting of Chromite Ore

The traditional chromite smelting technology involves charging the chromite ore into a submerged AC Electric Arc Furnace (Figure 1) and reductants (coke, coal and quartzite) added to reduce the ore into ferrochrome. The metal/ferrochrome and slag produced are tapped from the furnace for further processing. According to Naiker (2006),

Smelting chrome ore ScienceDirect

01/06/1975 The objective of chrome ore smelting is to convert the chromium into a form that can readily be used by the steelmaker. Although chrome has been smelted in blast furnaces, it more commonly is reduced in submerged-arc electric furnaces. The arc furnace is better suited to deal with the refractory nature of the gangue associated with the ore, to supply the large amounts of energy

Chromite ScienceDirect

01/01/2016 Ferrochrome is made by smelting chromite ore in an electric arc furnace with flux materials (quartz, dolomite, limestone, and aluminosilicates) and a carbonaceous reductant (wood chips, coke, or charcoal) (Kleynhans et al., 2012, USEPA,). The solid products obtained from smelting ferrochrome are metal, slag, and dust. In open top furnaces, the dust is collected in a bag filter plant, whereas in a

Chrome Ores on Ferrochrome Smelting

mine produces 3 grades of chrome ore, namely lumps, chips, and concentrates. The lumps and chips of chrome ores are used as raw material and are directly fed in submerged arc furnace, while the concentrates of chrome ore must undergo agglomerating treatment, such as sintering or pelletizing.

Chromium: Kazchrome completes chromite floatation trials

The recovery of chromite from both primary ore and tailings is most commonly achieved using spiral concentrators, which exploit the difference in specific gravity between chromite and gangue minerals to produce a chromite-rich concentrate. Although this process results in good recoveries in primary ore, spiral concentrator recoveries from tailings that have been subjected to extensive milling

This ore is then fed into the Beneficiation Plant where the entrenched waste is separated from the ore. Ore is separated in two sizes. Lump ore of between 10 to 85mm in size is separated from concentrate ore which is sized between 0 and 1mm. Waste is separated by dense medium separation and concentrate material is separated through a spiral centrifugal water process. Fine waste is separated

Chromite Wikipedia

Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds. It can be represented by the chemical formula of FeCr 2 O 4.It is an oxide mineral belonging to the spinel group.The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4). A substitution of the element aluminium can
