Question

define electrorefining of copper
​

Answer 1

Answer:

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. ... Electrons are produced at the anode. Electrons flow from anode to cathode.

Answer 2

Answer:

Electrorefining entails electrochemically dissolving copper from impure copper anodes into an electrolyte containing CuSO4 and H2SO4 and then electrochemically depositing pure copper from the electrolyte onto stainless steel or copper cathodes. The process is continuous.
