Zinc was extracted from metallurgical solid waste residue, a process using NH3–(NH4)2SO4–H2O system as the leaching agent has been applied for treatment of metallurgical solid waste residue particles. 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.
