Abstract
EAFD (Electric Arc Furnace Dust) is considered as pernicious pollutant, assigned hazardous waste. Since this dust is a by-product of industry, it contains valuable metals such as Fe, Zn, Ni, Cu which can be turned into resources by recycling process. In this study, hydrometallurgical process was applied to recover Zn from Electric Arc Furnace Dusts. The result showed 95% Zn recovery at 3M $H_2SO_4$, Solids/Liquid ratio 1:2 and aeration of 1.8L/min for 2hr. However there was 80% Zn recovery at lower $H_2SO_4$ concentration apply for pilot scale plant.
