Recent Development of EAF Dust Treating at Shisaka Smelting …

Fig. 8 Changes in amount
of high-zinc EAF dust
treated
(including powdery EAF dust), are shown in Fig. 8. The increased zinc recovery rate
for high-zinc EAF dust enabled us to treat approximately 50,000 tons of high-zinc
EAF dust in 2018.
Conclusion
Shisaka Smelting has greatly improved the technology used in its zinc recycling
over the 42 years since commencement of EAF dust treatment operation. The highzinc EAF dust treatment technology described in this report has been indispensable
for improving our application performance of raw materials and increase our cost
competitiveness. EAF dust treatment is gaining greater attention due to the growing importance of environmental conservation and resource recycling. We will continue to research and implement various improvements to the EAF dust treatment
technology to enable even more effective use of resources.
