Chrome Ores on Ferrochrome Smelting

Abstract—Chrome ores from six locations across the Bushveld Igneous Complex in South Africa are used to investigate the effects of ore types on the smelting processes, such as the consumption of fluxes, reductant; and most importantly, the consumption of electricity. The electric energy consumption is highly related to the SiO 2

Smelting chrome ore - ScienceDirect

Jan 01, 1976  Smelting chrome ore 855 Low carbon levels are more readily attained with a lumpy, coarse ore and when the slag has a MgO/Al 2 0 3 ratio of approximately unity. Higher values of MgO/Al 2 0 3 are especially deleterious. The presence of CaO also raises the carbon level. The influence of these factors can be explained by their effect on the ...

Ferrochrome - Wikipedia

Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures. Chromium ore (an oxide of Cr and Fe) is reduced by coal and coke to form the iron-chromium alloy. The heat for this reaction can come from several forms, but typically from the electric arcformed between the tips of electrodes in the bottom of the furnace and the furnace hearth. This arc creates temperatures of about 2,800 °C (5,070 °F). In the process of smelting,

Chromite - Wikipedia

Chromite is a mineral that is an iron chromium oxide.It has a 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 also occur, leading to hercynite (FeAl 2 O 4). ...
