What is Copper Cathode?

****

Copper ranks as the third most commonly used metal in the world, following iron and aluminum. Copper is known for being a soft metal with resistance to corrosion and having excellent thermal and electrical conductivity. Therefore, its extraction and purification are of great importance. Copper cathode is a product derived from copper that exhibits higher electrical conductivity compared to elemental copper. It is important to note that pure copper is not naturally found on Earth; it is typically found in combination with other elements such as iron, sulfur, and more.

The process of extracting copper involves heating copper ores to temperatures exceeding 1000 degrees Celsius, resulting in the formation of copper sulfate, sulfur oxide, and iron oxide. By further heating the copper sulfate, high-purity copper and sulfur dioxide are produced. Copper obtained through these processes has low electrical conductivity. To address this, copper cathodes are produced using the electrorefining process. During this process, impurities such as nickel, silver, gold, and others are separated from copper.

**Applications of Copper Cathode:**

Due to its higher electrical conductivity compared to aluminum, copper cathode is used in the production of ICs (Integrated Circuits) and as a raw material for manufacturing high-purity copper products. Copper cathode is also used by manufacturers of copper rods and wires, commonly referred to as copper wire.

Other applications of copper cathode include the production of copper molds, the manufacturing of bronze and brass alloys (which benefit from copper's improved hardness and expansion properties), use in transportation, the production of electrical components, military equipment, the construction industry, and more.

Nab Exir Paya Chemi Company is dedicated to helping copper producers achieve maximum copper extraction and purification using solvent extraction (leaching) processes with the production of products like CLX5640, CLX5774, and CLX984. This commitment aims to contribute to domestic production growth, self-reliance, and the advancement of our country and fellow citizens.
