Description

KES High-Capacity Rectifier Systems convert three-phase line-frequency AC power into DC power with adjustable voltage. A typical model engineered for the copper electrolysis industry, the 21KA 95V copper electrowinning rectifier delivers precisely regulated DC power to ensure stable and efficient cathode deposition. This high-efficiency electrolysis power system ensures uniform copper ion deposition on cathode surfaces through stable current output, producing high-purity electrolytic copper. Operational data confirms that the unit reduces energy consumption per ton of copper by approximately 8–12% while raising cathode copper grade to above 99.99%. Its unique thermal management design maintains continuous operation in 45°C ambient conditions, making it particularly suitable for processing complex secondary copper materials.

The rectifier’s technical advantages directly translate to production process optimization. Through precise control of deposition parameters, it not only enhances primary copper quality but also significantly improves recovery rates of precious metals from anode slime. Operational reports from multiple smelters indicate approximately 15% increased recovery efficiency for scattered metals like selenium and tellurium, along with over 30% extended electrode service life. These improvements deliver substantial benefits across the entire electrorefining process.

Product Applications

KES high-capacity rectifier systems are widely used in electroplating, electrolysis, electrochemistry, oxidation, electrophoresis, smelting, electroforming, communications, and other fields. Their main applications include the electrolysis of non-ferrous metals such as aluminum, magnesium, lead, zinc, copper, manganese, bismuth, and nickel; the electrolysis of brine and potassium salt for the production of caustic soda, potash, and sodium; the electrolysis of potassium chloride for the production of potassium chlorate and potassium perchlorate; heating applications such as steel wire heating, silicon carbide heating, carbon tube furnaces, graphitization furnaces, and melting furnaces; hydrogen production by water electrolysis; and other high-current applications.

Copper electrowinning rectifiers, a key product line within this series, are engineered specifically for copper electrowinning, delivering precisely regulated DC power for stable and efficient cathode deposition.

The Purpose of Copper Electrowinning

The primary purpose of copper electrowinning (EW), which produces electrowon copper, is to efficiently and economically extract high-purity metallic copper from a pregnant leach solution derived from low-grade ores or secondary materials, which are not amenable to conventional smelting methods. It is the crucial final step in the hydrometallurgical processing chain.
