Silver Salt Recovery Machine

The precious metal recycling machine independently developed and manufactured by Yueqing Lunshuo Technology Co., Ltd. is a high-efficiency precious metal recycling and processing equipment specifically designed for industries such as electroplating, jewelry, and precision electronics. It focuses on the resource-based recycling and utilization of gold and silver-containing waste liquids and materials, integrating three core technologies: high-frequency pulse electrolysis, ion membrane separation, and intelligent closed-loop control. It specifically addresses industry key points such as low recovery rates, high pollution, high operating costs, and complex operation of traditional precious metal recycling processes, achieving green, efficient, and high-purity recycling and reuse of precious metal resources.

Working Principle

The equipment adopts a rotating cathode + high-frequency pulse electrolysis core process, operating entirely through pure physical electrolysis without the addition of any chemical reagents. It can perform targeted electrolytic separation of gold and silver-containing liquids such as electroplating waste liquids, fixing solutions, etching solutions, and precious metal cleaning solutions. Under the precise control of the intelligent electronic control system, the current, voltage, and reaction time are monitored in real time to rapidly adsorb and precipitate gold and silver ions from the liquid, forming high-purity precious metal elements. The equipment adopts a closed-loop circulation design, allowing the treated mother liquor to be directly recycled, with no harmful gas leakage or waste liquid discharge, thus meeting the dual requirements of high-efficiency recovery and environmental safety.

Core Advantages

1. High Recovery Rate and High Purity: The precious metal recovery rate is over 99%, with directly recovered gold and silver reaching a purity of 95%-99.8%. The residual precious metal content in the treated waste liquid is less than 0.01 g/L, far exceeding industry environmental standards, minimizing resource loss and maximizing resource utilization.
2. Energy-saving and low-consumption, green and pollution-free: The equipment has extremely low energy consumption, with a total power consumption of only 100-150W, resulting in low operating costs. It abandons traditional chemical recycling processes such as sulfidation and displacement, eliminating the need for chemical reagents and consumables throughout the entire process. It produces no toxic waste gas or residue, truly achieving zero secondary pollution and meeting the environmental emission requirements of enterprises.
3. Intelligent and fully automatic, worry-free operation: Equipped with an intelligent touch-screen operating system, various operating parameters are visually adjustable. The equipment can operate fully automatically and continuously without the need for dedicated personnel, making it simple and easy to use. The machine body is made of corrosion-resistant high-quality materials, with a compact structure, convenient installation, and durable core components, simplifying maintenance and significantly reducing operating costs.
4. Strong adaptability and wide application: It can flexibly process various waste liquids and materials containing gold and silver, supporting customized processing volumes. It can also achieve single-machine or multi-machine combination operation, perfectly adapting to the production needs of large, medium, and small electroplating plants, jewelry processing plants, electronics companies, printing and plate-making plants, and other enterprises of different sizes.

Application Areas

Widely used in industries such as electroplating, jewelry making, printing plate making, medical X-rays, precision electronic component production, and circuit board etching, this equipment is specifically designed to recycle various gold and silver-containing waste liquids, cleaning wastewater, and processing waste, helping companies turn waste into treasure, effectively reducing the procurement cost of precious metal raw materials, and practicing green production concepts. It is an essential core equipment for cost reduction, efficiency improvement, and environmental compliance in the precious metal-related industries.
