purification of ores such as copper sulfide ore. 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).
