**What is Copper?**

Copper,is a metal with an atomic number of 29 and the chemical symbol Cu, is an intermediate metal on the periodic table of elements. Among its notable properties are high thermal and electrical conductivity, as well as the ability to withstand ductility and hammering (referred to as malleability) under pressure without breaking.

the position of Iran in the copper production

Given the strategic position of this mineral is clear. Due to having a high copper reserves of Ore  in Iran, various methods of copper production in Iran have been had a considerable progress .Pyrometalurgy and hydrometalorgy methods of copper production have increaased highly recently in Iran.  Nowaday more than 250000 Tons of catosic copper are produced anually.  In the hydromethalorgy production of  copper a versatile chemicla raegent is essntiall named CLX ( copper Leaching Extractant) which is locally produced. CLX have a good capability of copper absorption more than its simillay and forign regaents such as LIX, Acorga and mextral.

The strategy and programming of the Iranian copper industries will adopt to enter global markets and play a effective role in the global supply chain.

Iran’s copper reserves and mines are divided into two groups, large and small mines, based on their volume and quantity of reserves and grade

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.
