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.Inquire Now

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.Inquire Now

Zinc extraction kinetics was investigated by Kuo and Mikkelsen (1980) and the resulted data were described by an exponential rate equation. However, other equations have been proposed for describing extraction kinetics and they may provide better descriptions of Zn extraction from soil (Havlin et al., 1985; Sparks, 1986).
