Copper cathodes are high-purity copper sheets produced through the electrolytic refining process. They are the final product of refining copper ore and are used as a raw material in various industrial applications. The production involves dissolving copper ore in a solution and then electrolytically depositing pure copper onto a cathode plate. The resulting copper cathodes are typically 99.99% pure and are used in the manufacturing of copper products, such as wiring, pipes, and electronic components. Their high purity makes them essential for applications requiring excellent electrical conductivity and corrosion resistance.
