Purpose of the development: Recycling of valuable components from a rare phase; return the original characteristics of pickling solutions.

Recommended application field: Electronic and instrument-making industry.

Technical characteristic: The optimal parameters of the process; the amount of the metal powder at the stage of the exchange of the contact; pressure of chlorine in the oxidation of the etching solution components; The set values of pH and concentration of the solution digestion chlorination.

Advantages over analogues: Intensification of regeneration process, reducing the amount of oxidizing agents, providing non-waste recovery process.

The development stage readiness: Introduced in production

Technical and economic effect: Depends on the amount of etching solutions in the areas of etching.

Description of the development:
()
The method for regenerating the etchant waste FeCl3, which excludes contact recovering copper powder and iron oxidation in solution Fe (II) to Fe (III) with chlorine in the solution circulation of the adsorption tower.
