Copper cathodes are a vital component in the production of copper metal. They are high-purity copper sheets that serve as the starting point for various copper-based products and applications. They are large, rectangular sheets of high-purity copper metal. They typically measure around 1 meter (3 feet) in length, 1 meter in width, and 5-10 millimeters (0.2-0.4 inches) in thickness.

• Production: Copper cathodes are produced through a process called electrorefining. In this process, impure copper is used as an anode, while a high-purity copper sheet acts as the cathode. When an electric current is passed through the electrolyte, copper ions from the anode move to the cathode, depositing pure copper onto it.
• Purity: Copper cathodes are known for their high purity. The purity level is typically expressed as a percentage of copper content, with the most common grades being 99.99% pure (also known as “4 nines” copper) and 99.95% pure (also known as “3 nines five” copper).
• Physical characteristics: Copper cathodes have a smooth, shiny surface and a reddish-brown color. They are relatively soft and malleable, which makes them easy to work with in subsequent manufacturing processes.
• Uses: Copper cathodes serve as a primary raw material in various industries. They are used extensively in the production of copper wires, tubes, pipes, and other electrical components. Copper cathodes are also employed in the manufacturing of alloys, such as bronze and brass, which find applications in construction, transportation, electronics, and more.
• Trading and transportation: Copper cathodes are traded on commodity exchanges, and their prices are influenced by global supply and demand dynamics. Due to their size and weight, transportation of copper cathodes often requires specialized handling and packaging to ensure their protection during transit.
• Recycling: Copper is a highly recyclable material, and copper cathodes can be recycled to produce new copper products. The recycling of copper helps conserve natural resources and reduces the environmental impact associated with mining and extraction of new copper.

Copper cathodes play a critical role in various industries due to their excellent electrical conductivity, corrosion resistance, and malleability. Their high purity and versatility make them a valuable commodity in the global market.
