Petroleum Coke Particle Size Effects on the Treatment of EAF Dust through Microwave Heating


EAF dusts were mixed with petroleum coke and irradiated together under microwave for a pyrometallurgical treatment. It was found that particle size of the reducing agent played an important role in affecting the reduction degree. Both zinc removal and metallization degree increased with the decreasing of the coke particle size. By changing both microwave time and carbon addition, optimal zinc removal at 99.23 % and metallization at 100 % can be achieved with 15 minutes microwave irradiation and 20 wt% carbon addition.
