Abstract: In order to promote the development of valuable metal recycling technology in zinc dust and residue, two types of typical secondary zinc resources, such as electric furnace dust and zinc leaching residue, which are abundant resources and rich in zinc ferrite, were reviewed based on the principle of comprehensive utilization, technical routes and utilization effects. It is pointed out that the mineral phase reconstitution is an effective method to realize the comprehensive utilization of electric furnace dust and zinc leaching residue. The main valuable components of electric furnace dust are zinc and iron. After the mineral phase is reconstituted, the zinc component should be separated by mineral separation. The remaining products should be returned to the iron making process for recycling in the steel plant; The main valuable components in zinc leaching residue are zinc, iron, gallium, indium, silver, etc. After the mineral phase reconstruction treatment, according to the elemental trend, a combination method of mineral processing and wet extraction is adopted, and achieve the comprehensive recovery of valuable elements without the secondary pollution.

Key words: Secondary zinc resource, Zinc ferrite, EAF dust, Zinc leaching residue, Comprehensive utilization
