A new ligand selection model for leaching of low grade zinc oxide ores is proposed. The model demonstrates that the formation constant between ligand and zinc ions plays a significant role in the leaching process. A series of leaching experiments with different ligand concentration are conducted to assess the selection model. The results show that when nitrilotriacetic acid is used as the leaching agent, the highest zinc extraction is obtained. The zinc leaching rate is 84.33% in the presence of 0.4 mol/L nitrilotriacetic acid and liquid-solid ratio of 10 mL/g.
