Electrowinning / Electrorefining Cell Module
An integrated modular system for high-purity metal recovery — combining electrorefining and electrowinning into one compact, scalable solution.
How the Process Works
Cast anode metal tubes are first processed in the electrorefining section, where base metals are dissolved and separated while valuable metal slimes are collected. The recovered slime is then transferred to the electrowinning circuit for selective metal recovery and purification.
High-Purity Output: 3N to 5N
Through controlled electrowinning, the system refines metals to purity levels ranging from 3N to 5N (99.9% to 99.999%), depending on the metal type and process conditions — delivering exceptional product quality for precious metals, specialty metals, and other high-value materials.

Modular System Architecture
What's Integrated
  • Electrorefining cells
  • Electrowinning cells
  • Solution handling units
  • Filtration systems
  • Recovery units
  • Rectifiers (ER & EW)
Design Advantage
All components are built into one compact frame, eliminating the need for separate infrastructure. The modular design simplifies installation, reduces footprint, and allows straightforward capacity expansion as production demands grow.
Designed for Cast Anode Metal Tube Refining
The system is specifically engineered for cast anode metal tube processing. Anode tubes are loaded into the electrorefining section, where controlled dissolution separates impurities from the valuable metal content — ensuring consistent feed quality into the downstream electrowinning circuit.

Target Applications
Precious Metals
Gold, silver, and platinum group metals requiring ultra-high purity for industrial and investment-grade applications.
Specialty Metals
High-value specialty metals used in advanced electronics, aerospace, and energy technologies.
High-Value Materials
Any impure metal feed requiring selective purification and high product quality for downstream use.
Selective Recovery from Refining Slime
The Challenge
Electrorefining generates a valuable slime containing concentrated precious and specialty metals. Recovering these metals selectively — while excluding impurities — demands precise electrochemical control and robust solution management.
The Solution
The integrated electrowinning circuit accepts the slime directly, applying controlled current and chemistry to selectively deposit target metals at high purity. The result is a refined product ready for direct use or further downstream processing.
