Alkaline Etching Fluid Recycling And Copper Extraction Equipment

The process of recovering copper from alkaline etching fluid mainly includes the extraction electrolysis process and direct electrolysis process.

The alkaline etching solution regeneration and copper recovery system extraction process is the use of a special copper extractant on the high copper content of alkaline copper etching solution extraction – back extraction treatment to get copper sulfate solution after electrolysis in the cathode copper foil deposition to generate high-purity copper monomer and the extraction of alkaline etching solution is called etching regeneration solution. The etching regeneration solution maintains the original chemical composition of the etching solution, and through effective treatment and deployment, it becomes a regeneration sub-liquid with a stable etching ability to return to the etching line for etching, thus realizing the recycling of resources.

Alkaline etching solution regeneration and copper recovery system direct electrolysis process is the use of special materials composite cathode and anode on the high copper content of alkaline copper etching solution for direct electrolysis, cathode plate deposition to generate high purity copper monomers after the removal of the copper solution to maintain the etching solution of the original chemical composition, through effective treatment and deployment of regenerative sub-liquid with a stable etching capacity through the specific gravity of the signal is automatically controlled by the addition of the return etching line to etching work, thereby realizing the recycling of resources, thus realizing the recycling of resources.
