purifying copper by electrolysis
Extraction of Copper - Purification by Electrolysis. High purity copper is needed to make electrical wires. The anode is a block of impure copper. The cathode is a thin piece of pure copper. The electrolyte is copper sulfate. When electricity is passed through the cell copper is dissolved at the anode by oxidation and Cu 2+ ions go into solution.

Extractive Metallurgy of Copper - Meaning, Method and
The most common ore used in the copper extraction is Chalcopyrite (CuFeS 2), also recognized as Copper Pyrites and other such sulfides. The proportion of copper in the real ore is too limited for straightforward copper extraction to be feasible. The concentration of ore is required, and the Froth Flotation method is used for this process.
