high purity copper electrochemical refining

The Electro Refining Process :: Total Materia Article

Electrochemical processing is used both in the primary extraction of metals from their ores and in the subsequent refining of metals to high purity. Both operations are accomplished in an electrolytic cell, a device that permits electrical energy to perform chemical work.
