Cathodesearch for term

The result of the electrowinningi process is cathodei copper (or a cathode) that is generally 99.99 percent copper or higher in grade. The cathode starter sheet (either stainless steel or a copper blank) is placed into the electrowinning solution and a DC charge is passed through the system. The cathodes are negatively charged and attract the positively charged cathode ions, causing them to adhere to the starter sheet and create a copper cathode.
