Abstract

The thermodynamic analysis on chromium ore pellets in solid reduction chromium process is carried out, the result of which is validated by pre-reduction experiment of cold briquetted chromium ore. Polarization Microscope and SEM are employed to observe microstructure and element composition. The thermodynamic analyses indicate that the Cr2O3 will be reduced to metallic chromium in solid reaction with the ratio of CO and CO2 pressure reaching 2017 at 1200 °C. The experimental results agree well with the thermodynamic analyses.
