The components of the reaction system consisted of the synthetically prepared slag (Table 1), the natural chromite ore (Table 2), the graphite crucible (with carbon as reductant) and the metallic phase. When the chromite ore was charged into the molten slag, it dissolved in the slag, and as a consequence changed its overall composition.

Ferro-alloys are made by charging the non-ferrous metal or concentrate with iron or iron ore, coke or coal, and fluxes, and smelted at high temperature in electric-arc furnaces. Aluminum or silicon is sometimes used as reductant in the process depending on the particular alloy being produced, such as Ferro-chrome.

Inference on Beneficiation Results of Low-Grade chromite Ore.
