Answer 2

sorry idk :(

Answer 3

Copper in ore is usually oxidized (has given an electron away). Melting or dissolving the oxidized copper allows the copper to go off in search of electrons elsewhere. In the case of electro-refining, a negatively charged plate.

Answer 4

thank you

Answer 5

Actually, that's not the purpose, that's the process.

Answer 6

Electro-refining of copper is used to remove impurities from copper because copper in its natural state isn't very pure.

Answer 7

And of course, for delicate things such as cables and so on, the resistivity of the conductor (mostly copper) has to be controlled.

Answer 8

Right! Left that part out. I spent too long on the drawing. Purpose, remove impurities.
