Electrolytic copper

With electrolytic copper , a is by electrolysis shape of the obtained copper designated. The galvanic deposition of the metal enables very high degrees of purity to be achieved. Electrolytic copper in the narrower sense is copper metal with a purity of more than 99.9%.

Electrolytic copper is extracted from copper ore . This is available as carbonates (carbon content) and sulfates (sulfur content). The copper-containing components are prepared for smelting by breaking , grinding and separating the residual rock . In the smelting process, sulfur, carbon and water are removed and melted into suitable plates (copper anodes ) for the subsequent electrolysis. In addition to copper, these copper anodes also contain other impurities. During electrolysis with direct current , copper ions are released from the anode plate and migrate to the cathode , on which the copper ions attach to form electrolytic copper.

Electrolytic copper is mainly used as a semi-finished product in electrical engineering ( transformers , printed circuit boards , wires, cables, etc.), in automotive engineering and in the construction industry.

Electrolytic copper is listed on the stock exchange as German electrolytic copper for conducting purposes (DEL notice).
