Copper cathode is a high-purity (typically 99.99% Cu) form of copper, produced via electrolytic refining or electrowinning. It appears as large, flat, rectangular plates weighing 100–250 kg. As a primary raw material for copper rods, wires, and sheets, it is essential for electrical, construction, and, crucially, electronics industries.
