Abstract

The present invention relates to an eco-friendly zinc smelting method, and provides a method for treating zinc ferrite, the method comprising the steps of: generating a fumed metal oxide, sulfite offgas, and eco-friendly clean slag through a fuming process of zinc ferrite generated from a zinc wet smelting process; reacting the fumed metal oxide with the sulfite offgas generated from the fuming step to convert the same into a solid of a metal-sulfate compound and/or metal-sulfite compound; and reacting the metal sulfite compound with sulfuric acid to decompose the same into a metal sulfate compound and a concentrated sulfite gas.
