Scrap computers, cell phones and other electronic devices are good sources of gold, silver and other valuable metals. During recycling, components are dissolved in baths of acid or cyanide. An electrochemical process -- electrolysis -- extracts the gold by depositing it onto electrodes.
The electrolyte solution you made will dissolve the gold from the scrap, and the positive charge in the gold will cause it to attract to the negatively charged steel. All of the gold in the electronics scrap will form onto the steel, where it can be peeled off and set aside until you have enough to refine.
Electrorefining is a much more common process than electrowinning and such plants occur throughout the world on scales between 1000-100,000 ton/year. Usually they are part of a larger operation to separate and recover pure metals from both scrap and primary ores. Therefore, the process must be designed to handle a
