Abstract

Chromium has a wide range of applications, including as an alloy addition in various steels and also as a corrosion resistance coating. Carbothermal reduction of chromite ore (FeCr2O4) in a submerged arc furnace is an important industrial process for extracting chromium, but the energy consumption is excessive. It is suggested that one area for future research is the low temperature carbothermic solid state reduction of chromite to produce an intermediate product, which can subsequently be upgraded to ferrochromium . In this regard, a thermodynamic model has been developed to investigate this process and the effects of temperature , carbon additions and ore composition on the recovery of chromium and the grade of the ferrochromium , have been studied. Further development of the model may allow it to be applied to the simulation of other processes for the recovery of chromium from chromite ores.
