Electrolytic Refining Meaning, Electrorefining of Copper

In this phase of electrolysis copper sulfate divides into a positive ion of copper (Cu ++) and a negative ion of sulfate (SO4 —). The positive copper ion (Cu ++) or cations travel towards the negative electrode made of pure copper where it absorbs the electrons from the cathode. Cu atom is deposited on the cathode’s graphite layer.

Electrorefining Chemistry Tutorial AUS-e-TUTE

Electrorefining Copper. During the electrorefining stage of copper production, a series of impure copper anodes and thin starter sheet cathodes (such as thin copper foil) are suspended in a tank. The electrolyte containing the copper ions flows through tank. The electrolyte is often copper dissolved in sulfuric acid which produces an aqueous solution of copper ions. An external power supply is

Electrorefining an overview ScienceDirect Topics

A process flow diagram for a typical silver electrorefining operation is shown in Figure 34.11. Two important unit operations are the production of freshly made electrolyte and the treatment and recycling of silver in the spent electrolyte. Fresh electrolyte, containing up to 400 g/L silver, is typically produced by the dissolution of refined but off-specification silver crystal into nitric

Copper electrowinning: theoretical and practical design

Copper atoms diffuse through the solid phase to a location in an appropriate site of the crystal lattice. Adsorption and nucleation steps are considered to be included in the Heterogeneous Electron Transfer reaction rate mechanism. The overall rate is controlled by the slowest step which can be either mass transfer or reaction kinetics. For the purposes of copper electrowinning reactor design
