The make and chemical composition of zinc-bearing dust in the iron and steel plants at home and abroad, as well as the research status and problems existing in recovering zinc from the zinc-bearing dust of iron and steel plant at home and abroad were introduced in this paper. It was pointed out that, the zinc-bearing dust should be classified and treated according to different zinc phases in the dust. It is thought that the ore phase restructuring of calcified roasting-recovery of zinc by ammonia leaching process is a new technical idea for zinc-bearing dust treatment in iron and steel plants.
