Application of zinc ferrite reduction in the extraction of Zn, Ga and In from zinc refinery residue

Extraction of gallium and indium from zinc refinery residue (ZRR) has continued to attract attention because different mineralogy residues occurrences trace elements in ZRR. About 90% is currently extracted Bayer liquor, whereas, ZRR been a primary source for recovery. The production USA zero. However, are promising resource the extraction critical metals such as gallium, germanium indium. major problem concentration ferrite (ZF) which refractory leaching. current study introduces method enhance leaching kinetics having ZF constituent. In this study, was partially reduced with reducing gas containing 10% H2 roasting product then leached under conditions. effect reduction found have significant impact on decomposition eased zinc, More than target achieved process. manuscript also discusses characterization using laser ablation inductively coupled plasma-mass spectrometry (LA ICP-MS), scanning electron microscopy (SEM), x-ray diffraction (XRD) automated mineralogy.
