The content of metal elements in the waste liquid of copper etching liquid is very high. If it can be recycled, it will also expand the interests of the enterprise. Therefore, many companies want to do the project to extract metal elements from waste liquid. There are several methods for extracting copper from copper etching liquid, such as reduction method, replacement method, solvent extraction method, etc. Using the centrifugal extractor, and the solvent extraction method is adopted, and the appropriate extractant is selected to extract and recycle copper from the waste liquid of copper etching liquid, with significant results.

Method process for extracting copper from copper etching liquid

The extraction of copper mainly includes extraction-washing-stripping-regeneration and other processes. The selected extractant and copper etching liquid are injected into the centrifugal extractor according to a certain ratio. Through the mixed mass transfer of the equipment, the metal elements are transferred to the extractant and discharged from the body through the outlet.

The discharged loaded organic phase is washed to remove the chloride ions in the organic phase, and then stripped and the subsequent regeneration stage operation is performed.

Equipment for extracting copper from copper etching liquid

The CWL-M centrifugal extractor developed and produced by Zhengzhou Tiei Extraction Technology is developed to address the shortcomings of traditional extraction equipment. Its power consumption is only 10% to 30% of that of traditional annular gap extractors. At the same time, the centrifugal extractor has a short stage retention time, rapid phase separation, high extraction efficiency, and saves investment costs and solvent recovery and regeneration costs.

The model and material of the CWL-M centrifugal extractor can be selected, and it can be customized and purchased according to the customer's processing volume and liquid system to meet the different production requirements of customers.
