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 ...

Smelting chrome ore - ScienceDirect

Jun 01, 1975  SMELTING REACTIONS In the smelting process the electric furnace is charged with the chrome ore, a carbon reducing agent, and a flux, usually quartz. Reaction of these materials produces slag and liquid ferrochrome, which are withdrawn from the hearth, and carbon monoxide, which rises through the descending charge.

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
