CLX5640

CLX5640 is a copper leaching extractant used in the hydro-metallurgical process of copper extraction, including leaching and solvent extraction. It is a domestically produced product used in many copper cathode production units and factories in Iran. This product has gained widespread acceptance due to its high quality and performance, often surpassing foreign counterparts and Mextral5640 in various parameters.

Here are some key features and benefits of CLX5640:

1. High Copper Absorption: CLX5640 exhibits a high level of copper absorption, often superior to external samples of PLS (Pregnant Leach Solution).

2. Loading and Saturation: It allows for high loading and saturation levels in the pregnant leach solution.

3. Efficient Stripping and Copper Transfer: CLX5640 facilitates excellent stripping and copper transfer, ensuring efficient copper recovery.

4. High Selectivity: It offers excellent selectivity, particularly in terms of Cu/Fe selectivity.

5. Minimal Manganese Absorption: This extractant does not chemically absorb manganese, which can be a common problem in copper leaching processes.

6. Rapid Separation: CLX5640 exhibits favorable kinetics for absorption, phase transfer, and separation, resulting in minimal separation time.

7. No Formation of Undesirable Impurities: It does not lead to the formation of undesirable impurities like crud.

This product is crucial for copper cathode production using leaching and bio-leaching methods. It addresses the challenge of removing interfering ions such as iron and manganese, as well as silica, which is a common concern in many copper production facilities.

One of the notable advantages of using domestically produced CLX5640 is its competitive pricing compared to similar foreign products. It ensures a continuous and timely supply, ease of access, and free consultation regarding various product grades and models. The product is highly versatile and can be customized to meet specific customer requirements within the PLS system.

The chemical composition of CLX5640 includes a mixture of aldoxime and a specific hydrocarbon ester or high-flash-point solvent, enhancing its stripping power and optimizing its physical properties such as viscosity and density for effective use in the copper extraction process.

CLX5640 finds various applications, including initial charging of SX systems, daily or monthly makeup, bio-leaching processes (initial charge and daily injection), copper recovery from industrial wastewater containing significant copper ion concentrations, and copper extraction from sludge produced during aqueous processes.

The reaction of this extractant with copper ions is represented as follows:

2ROH(org) + Cu2+SO4(aq) ↔ (RO)2Cu(org) + 2H2SO4(aq)

CLX5640 plays a critical role in optimizing the copper extraction process, ensuring high-quality copper cathode production.
