摘要：
A study was carried out on the volatilization kinetics of Zn in the pellets made of Zn-bearing dusts mixed with coal powder in a nitrogen atmosphere and within the temperature range between 1 100℃and 1 300℃.The study shows that the reduction temperature has a significant effect on the volatilization rate of zinc and that either the coal particle size or the excess carbon content has no effect on the volatilization rate.The obtained activation energy for the volatilization of zinc is79.42 kJ/mol.The volatilization rate of zinc is controlled by the reaction between the zinc oxides and CO.
