Implication

Randomized trial demonstrates effective recovery of Zn, Fe, and Pb in zinc-containing solid wastes, suggesting a sustainable waste management strategy.

Key Points

The aim is to develop a new strategy for recovering valuable metals from zinc-containing solid wastes in the steel industry.
Implemented a synergistic ammonia-acid leaching strategy on blast furnace dust and secondary zinc oxide.
Optimized ammonia leaching conditions with specific ratios and pH for selective metal extraction.
Utilized acid leaching to recover residual zinc and lead while managing waste ratios for efficient separation.
Achieved 70.62–88.08% zinc extraction with <1% residuals across processes.
Dissolved 95.7% of residual zinc and effectively recovered lead using optimized leaching conditions.
Enhanced zinc sulfide leaching efficiency by integrating blast furnace dust, resulting in 73.42% Fe-enriched materials.
