The refining anodes taken out from the refining furnace is changed into electrolytic copper with purity of 99.99% through an electrolysis process: During electrolysis, copper (II) ions leave the impure copper anode and since they are positive, migrating to the negative cathode. From time to time, the pure copper is scraped off the cathode.

The end result of of the copper smelter operations is anode copper which is 99% pure (see graphic on the left). An example where copper is further purified is at the Asarco electrolytic plant in Amarillo, Texas. The 99% pure copper from the anode furnace is cast into 750-pound, 3-inch thick, rectangular slabs called anodes. The final step is a process called electrorefining. This is done by ...

Copper electroplating fundamentals

Unlike TSV and DD wafers, which are coated with a copper seed layer across the entire wafer, pillar wafers have a copper seed layer only at the bottom and photoresist that has been patterned on top to define the features. Suppressor wets the photoresist and the leveler enters the via during the 7- to 8-minute plating process, to help create a pillar with a flat top. Both leveler

Electrowinning - an overview ScienceDirect Topics

Electrowinning is the plating of metallic copper from the CuSO4 –H 2 SO 4 –H 2 O electrolyte produced by solvent extraction. It consists of passing direct current between inert but conductive anodes (usually Pb–Sn–Ca alloy) and stainless steel (sometimes copper) cathodes. The cathodic copper deposit is similar to that from electrorefining.
