Metso has unveiled a new robotic solution aimed at improving efficiency and flexibility in copper electrorefining, introducing its Outotec Robotic Split Strip technology for cathode stripping operations.
Designed for both new and existing plants, the system separates cathode sheets from cathode plates using a combination of robotics and advanced hydraulic control. The compact design is intended to streamline the stripping process, delivering greater precision while reducing waste and supporting more sustainable operations.
According to Metso, the Robotic Split Strip replaces the large mechanical structures typically used in conventional stripping machines with a more integrated and flexible setup. By incorporating robotic technology, the system reduces the number of fixed components, enabling simpler layouts and improved access for operators and maintenance teams.
Metso technical product manager Peter Nord said the technology addresses key challenges in traditional stripping systems, particularly around installation complexity and maintenance requirements.
“Traditional split strip machines rely on larger mechanical structures and a higher number of components, which increase installation effort, spare part needs, and maintenance time,” Nord said.
“In comparison, the Robotic Split Strip introduces a compact and highly integrated design, with advanced robot technology replacing several fixed mechanical functions.”
Nord added that the system’s hydraulic technology enables precise, individual control of movements, improving performance in more challenging conditions such as sticky cathode plates.
The company said the solution offers a smaller footprint and lower weight, reducing structural requirements, while also delivering improved reliability through more precise control systems. Reduced componentry is expected to minimise downtime and simplify maintenance, while the modular design allows for flexible plant layouts and retrofit integration into existing stripping machines.
Metso said these features support faster commissioning, easier operation and a lower total cost of ownership compared with traditional technologies.
The launch builds on Metso’s long-standing position in hydrometallurgy, with the company drawing on more than 40 years of experience in cathode stripping and a global installed base of over 350 machines.
