| Abstract: |
| Composition, structure, roasting, and acid leaching of ammonium jarosite residue were investigated to achieve the goal of effective separation and usage of In/Zn and Fe in residue. The analysis results of MLA show that structure of jarosite residue is NH4Fe3(SO4)2(OH)6, Fe is mainly in structure of NH4Fe3(SO4)2(OH)6, and Zn is mainly in structure of Zn[SO4]?H2O. Acid leaching rate of In, Zn, and Fe is 82% above, 95% above, and 10% below respectively after roasted at 680~720 ℃ for 1.5 h. In, Zn, and Fe are efficiently separated from ammonium jarosite residue. |
