A study on the zinc removal kinetics and mechanism of zinc-bearing dust pellets in direct reduction

Deqing Zhu et al.

Summary: This study demonstrates that direct reduction technology can efficiently extract iron and zinc from zinc-bearing dusts, with the efficiency of zinc removal controlled by Jander three-dimensional diffusion. Analysis of the microstructure and elemental composition of the pellets showed that zinc in the dust exists in different forms, and the process of zinc removal can be divided into four stages based on the efficiency and microstructure of the reduced pellets.
