Abstract

The effect of the addition of El-Dekhilla waste pellets fines (E) upon the quality of El- El-Baharia iron ore (O) briquettes was investigated in this study. The kinetics of the reduction of the briquettes formed having different composition using hydrogen gas was studied at different temperatures (700°C-950°C). The results indicated that best ore reduction was achieved at 950°C. The kinetic of the reduction process was studied using different models and the best-fit models determined was (Kt = 1-(1-R)P 1/2P and kt = R+ (1-R) ln (1-R)). XRD analysis was used to identify the main crystalline phases present within the reduced briquettes at the optimal temperature and it was found that the metallic iron (syn. Fe) was predominantly formed.
