<p>The treatment of high-temperature and high-acid zinc leaching residue has attracted significant attention. However, when the content of valuable elements in the residue is low, the recovery cost becomes high. Therefore, there is an urgent need to develop efficient and environmentally friendly treatment methods. This paper proposes a roasting treatment method for zinc leaching residue, using pyrite as the sulfur source. The effects of roasting temperature, time, sulfur content, and air flow rate on the phases of Zn, Pb, and Fe in the residue were investigated. The optimum roasting process using pyrite was determined through a single-factor experiment. The results showed that the proportion of zinc-iron spinel increased significantly to 3.48%, and the relative content of lead sulfate increased to 0.87% after roasting. The total iron content reached 16.89%, with sulfides (such as pyrite) accounting for 0.93%. These results indicate that the roasting process enhances the chemical stability of the residue, providing a basis for the development of low-energy, harmless treatment methods for high-temperature and high-acid zinc leaching residue.</p> Graphical Abstract <p></p>
