Article ID: 1003-6326(2005)03-0706-05 Copper electrodeposition from cuprous chloride solutions containing lead, zinc or iron ions M.Tchoumou1, M.Roynette Ehics2 (1. Faculty of Science... deposits. During electrodeposition of copper from cuprous solution in the presence of various concentrations of lead, zinc or iron ions at different current densities, it is observed that lead is codeposited......
that the zinc leaching residue mainly consists of super refined flocculent particles including zinc ferrite, sulfate and silicate. The physical structural analysis showed that it has a thermal instability... mainly presents in the phases of zinc ferrite (ZnFe2O4), zinc silicate (Zn2SiO4), zinc sulfide (ZnS), zinc oxide (ZnO), and zinc sulfate (ZnSO4). The chemical approach was applied to determining......

School...: Considering the great variation of iron and zinc mass fraction and poor filtration performance in the goethite residue from zinc hydrometallurgy plants, the goethite residue samples from different......
of indium (Ⅲ), gallium (Ⅲ), and zinc (Ⅱ) from aqueous sulfate solution with Levextrel resin containing di(2-ethylhexyl) phosphoric acid (CL-P204). The aim of the research is to collect preliminary results for a pilot-scale production. Properties of adsorbing indium (Ⅲ), gallium (Ⅲ), and zinc (Ⅱ) from sulfate solution with the Levextrel resin were first studied by batch operation and column operation......
