Abstract：Leaching residue of zinc hydrometallurgy and jarosite residue were the common solid wastes in zinc hydrometallurgy process, which were prohibited for import in China. The content of zinc in these two solid wastes was relatively high, so they were usually pretended to be zinc concentrate for import to China. Therefore, it is necessary to identify the leaching residue of zinc hydrometallurgy and jarositeresidue. Firstly, the elements in obtained powdered sample were analyzed by X-ray fluorescence spectrometer (XRF). It was found that the elements in leaching residue of zinc hydrometallurgy mainly included Fe and Zn, while the main elements in jarosite residue were Fe, S and Zn. Moreover, both the two solid wastes contained As, Cd, Ga, In and Ag. Secondly, the phases in powdered sample were analyzed by X-ray diffractometer (XRD). The results showed that the main phase in leaching residue of zinc hydrometallurgy was ZnFe2O4 with little PbSO4, Zn2SiO4 and ZnS, while jarosite residue mainly contained KFe3(SO4)2(OH)6, ZnFe2O4 and Zn2SiO4. The method for identification of leaching residue of zinc hydrometallurgy and jarosite residue was established, which provided technical support for the supervision of imported solid wastes.
