The alkaline etching fluid recycling copper extraction system is used to treat and recycle the alkaline etching solution used in the copper etching process. It extracts and recycles the copper ions in the solution by recycling it, thereby reducing the need for waste liquid treatment, reducing costs, and improving resource utilization efficiency. The system usually includes liquid circulation, copper recovery and regeneration treatment, and the final liquid cleaning and filtration steps.

Alkaline Etching Fluid Recycling Copper Extraction System Process
The process of recovering copper from alkaline etching fluid mainly includes the extraction electrolysis process and direct electrolysis process.
Extraction Electrolysis Process
The extraction electrolysis process in an alkaline etchant recycling copper extraction system is a critical step for extracting and recovering copper from the etchant. This process is highly efficient and environmentally friendly, and by recycling and recovering copper, it reduces the need for fresh resources and lowers the cost of waste solution disposal.
Working Principle and Process
The alkaline etching fluid recycling copper extraction system adopts the process of extraction separation – electrodeposition of copper. Extraction separation is to separate the copper ions in the waste etching solution so that the waste etching solution can be regenerated. After adjusting the parameters, the regenerated etching solution can be returned to the etching machine for recycling. The electrodeposition of copper is the electrodeposition of extracted copper ions into high-purity electrolytic copper.
Features
The waste etching solution is regenerated, and the regenerated etching solution can be recycled.
The copper ions in the waste etching solution and ammonia washing water were recovered to reduce to high-purity copper with a high copper recovery rate.
The equipment is simple to operate and maintain and does not affect production during installation and debugging. After installation and debugging, it can be put into use.
