electrowinning of zinc, into the leach solution. Caustic soda is the most suitable lixiviant in this respect for the amphoteric lead and zinc. In the caustic soda leach process, lead and zinc are selectively dissolved in sodium hydroxide solution rejecting nonamphoterics in the residue. The process has been

Copper removal from diluted cyanide wastewater by ...

The influence of some process variables was evaluated by thermodynamic and voltammetric studies. The solution flow rate and temperature increase favor copper deposition. It was also verified, by voltammetric and electrolytic tests, that the presence of copper oxide on the anode surface catalyses cyanide oxidation.

copper and the cyanide has proven to be problematic. Direct electrowinning of copper from waste streams has also been investigated (Lemos et al., 2006, Dutra et al., 2008; Lu et al., 2002a) but generally has a low current efficiency, due to the low copper concentrations, with a .
