The Electrowinning Process: Part One :: Total Materia Article

The Electrowinning Process: Part One. The electrowinning process is a relatively traditional method to recover waste metals through the rinse system and at the same time reduce waste water generation and chemical discharge. The most common metals recovered using electrowinning are gold, silver, copper, cadmium and zinc due to their relative value.
