Copper Element information, properties and uses ...

Copper is one of the few tracer metals that is essential for all species. For the most part the biological requirement of copper is quite low as only a few enzymes such as cytochrome oxidase and superoxide dismutase require copper at their active sites. These generally rely on the oxidationreduction cycling and play an important role in respiration.

Copper production environmental impact

The copperbearing solution, from the solvent extraction operations, is plated into pure copper cathodes using a process called solution exchange electrowinning (SXEW). Stainless steel blanks are added to the plating tanks to act as cathodes and copper is plated onto them by electrochemical deposition.

Why is CuSO4 used as electrolyte while purifying copper?

1 Answer. Copper dissolution is the main oxidation halfreaction at the anode, and the oxidation of anions from the electrolyte needs to be minimized, since it is an unwanted side reaction which reduces current efficiency of the process.
