In order to develop a zinc recovery process from zinc-bearing dusts generated from ironmaking and steelmaking plants, fundamental A circulating fiuidized bed process has been investigated to treat dusts from steelworks.10) A zinc smelting process using zinc oxide or sulfide ores has been developed and commercialized in the non-ferrous metallurgical industry.11) However, it seems to be impossible to introduce this process into steelworks for treatment of zinc-bearing dust due to the low zinc concentration.The purpose of the present study is to develop a zinc condensation process from zinc-bearing dusts generated in steelworks, by use of sensible heat of hot metal. 2.Properties of Zinc-bearing Dusts Generated from lronmaking and Steelmaking Plants Zinc-bearing dusts are generated from ironmaking and steelmaking plants in steelworks.
