Zinc processing solutions typically contain modest concentrations of MgSO 4 (2–15 g/L Mg) and of MnSO 4 (2–11 g/L Mn) James et al., 2000, Dutrizac, 1996. Although MgSO 4 appears to be chemically "inert" throughout the zinc process, manganese is partly oxidized at the anodes of the electrowinning cells. Both species have an important ...
zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products.. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre. It has only moderate hardness and can be made ductile and easily worked at temperatures slightly above …

Then Ca, Sr, and Mn were selectively separated from the leachate via chemical precipitation and solvent extraction. Eventually, four metals of Sr, Ca, Mn, and Zn are successfully recovered from the ZECS by the integrated process of carbothermal reduction roasting-acid leaching-selective precipitation-multistage extraction.

Hence, a novel method for the selective recovery of Zn and Mn from waste zinc–manganese batteries by autocatalytic reduction roasting followed by a leaching process was proposed. The transformation of Zn and Mn during the comprehensive utilization process was investigated using thermomechanical analysis, XRD, ICP, etc.
