Metallurgical solid waste residue contains a certain amount of Zn, which are important secondary resources for the production of Zn. In this article, a hydrometallurgical method in a NH3–(NH4)2SO4–H2O system is proposed to recover Zn selectively from metallurgical solid waste residue. The results showed that the highest zinc extraction of 77.55% was obtained by using a total ammonia concentration of 5 mol/L of the leaching agent, stirring speed of 400 rpm, ammonia/ammonium ratio ([NH3]/[NH4]+) of 1:1, solid/liquid ratio of 1:4, leaching time of 30 min, and leaching temperature of 25 °C.
