  • Separation of zinc, cadmium and nickel from

    The soluble zinc species are stable up to a pH of about 6, after which zinc precipitates as Zn 2 (OH) 3 Cl. It is also evident that ZnCl + cations contribute a very small amount as compared to Zn 2 +. Contrary to zinc, cadmium forms CdCl + and CdCl 2 aqueous species, with the amount of Cd 2 + being negligible.

  • Zinc: smelting, producing and classification-Metalpedia

    Zinc smelting; Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method. Secondary (recycled) zinc material, such as zinc oxide, is also processed with the zinc sulfide.
