Drum electrodes have been widely used in electroplating industries. The design of drum allows uniform

electroplating with independency of volume processed. Previously rotating drum technology has been

employed for recycling processes like separation of materials such as plastics and wastewater treatment

[1, 2]. Rotary drum electrode has also been studied for extraction of Cu, Ag, Ni, Fe and MnO₂ via

electrolysis [3, 4]. To explore the potential for drum in field of recycling for separation of materials and

refining electrolysis, a modified rotary drum electrode has been developed. This drum electrode can be

effectively used for separation of metals from plastic and refining electrolysis of materials irrespective

of their shape and size. The innovative and flexible design allows treatment of feedstock at efficient

rate. The drum electrode can be used especially for electrochemical separation techniques to recycle

material and obtain high purity fractions of metals.
