Why is copper purified by electrolysis? Explained by FAQ
What happens to the copper ions during electrolysis? Electrolysis uses an electrical current to move ions in an electrolyte solution between two electrodes. In copper electrolysis, when a current is applied, positively-charged copper ions (called cations) leave the anode (positive electrode) and move toward the cathode (negative electrode).

During the purification of copper by electrolysis?
Why is electrolysis used in the extraction of copper? Copper is well below carbon (less reactive) and so can be displaced by carbon from its compounds eg copper oxides or sulfides. Electrolysis to copper pipes can happen when stray direct current (DC) electricity causes the copper to break down or disintegrate. Metals that are different

Electrochemistry of Molten Sulfides: Copper Extraction
2015-12-31 The electrolytic extraction of liquid copper at 1105°C from a molten sulfide electrolyte composed of 57 wt% BaS and 43 wt% Cu 2 S was investigated. DC cyclic voltammetry, Fourier transformed AC voltammetry, and galvanostatic electrolysis revealed that the electrodeposition of copper is possible in the selected molten sulfide electrolyte.

2022-5-30 Why is oxygen produced in electrolysis of copper sulphate? Copper is less reactive than hydrogen, so copper (Cu) is produced at the negative electrode. The half equation is: Cu2+ + 2e- → Cu The hydroxide ion is more reactive than the sulphate ion, therefore this forms water (H2O) and oxygen at the positive electrode.
