Effective diffusivity for CO-CO 2 gas mixture in Hot Briquetting Carbon Composite Iron Ore (CCB) at a temperature range of room temperature to 673 K was measured by Wicke-Kallenbach Method. The results obtained are summarized as follows; (1) Effective diffusivity of CO-CO 2 gas mixture through CCB increased with increasing temperature and fractional reaction of CCB. The effective diffusivity for CO-CO 2 system in CCB was proportional to the 1.50 power of temperature. (2) Kundsen diffusion and surface diffusion are negligible in regard to diffusions of CO and CO 2 in CO-CO 2 gas mixture in CCB. Therefore, diffusions of CO and CO 2 in CO-CO 2 gas mixture in CCB are described by molecular diffusion.
