how copper can be electrofine
Answers
Copper is usually mined from its coal known as blister copper. It is about 98 to 99 per cent pure. However, the electro-refining process can easily make it 99.95% pure which makes it a good product to be used in electrical components.
A block of impure copper is taken as an anode or positive electrode. Copper sulfate which is acidified with sulphuric acid is used as a graphite-coated electrolyte along with pure copper tubes, as a cathode or negative electrode. 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.
The cathode is coated with graphite in the process of electrolytic metal processing or merely electro grinding so that the concentrated material can be easily removed. This is one of the most growing electrolysis procedures.

Copper is superconductor
