Abstract

Technology for copper coatings removing from spent parts made of dielectric by anodic dissolution without formation of secondary waste and with simultaneous copper deposition on the cathode is proposed. The kinetics regularities of copper electrodeposition and electrodissolution from pyrophosphate, tetrafluoroborate and mixed pyrophosphate-tetrafluoroborate electrolytes are studied. Electrochemical technologies for copper-containing waste treatment in pyrophosphate-tetrafluoroborate electrolytes to obtain marketable products are proposed. Technology of high-speed treatment to produce phosphorus-containing copper anodes and method of manufacturing of copper electrodes with mechanically strong and high electrochemically accessible surface area in the form of dendrite structures, that are well-coupled with substrate are proposed
