Titanium Anodes for Metal Electrowinning Systems
Engineered for copper, zinc, nickel, cobalt, and industrial metal recovery processes. Hele Titanium provides MMO coated titanium anodes, PbO₂ electrodes, custom titanium electrodes, and project-specific anode assemblies for acid electrowinning, hydrometallurgy, and electrochemical metal recovery systems.
High-Purity Metal Recovery
Metal electrowinning uses controlled electrochemical deposition to recover metals from aqueous electrolytes in mining, hydrometallurgy, recycling, and industrial wastewater streams.
Electrolyte composition, acidity, chloride content, current density, temperature, target metal, and anode coating stability directly affect current efficiency, energy consumption, metal purity, and service life. Hele Titanium supports these systems with MMO coated titanium anodes, PbO₂ electrodes, custom titanium anodes, and project-ready documentation.
For electrowinning projects, anode selection should be based on metal target, electrolyte chemistry, operating current density, cell configuration, coating requirement, service life expectation, and documentation needs.
Working Principle
In an electrowinning cell, metal ions in solution are reduced and deposited at the cathode. The anode supports the required anodic reaction while maintaining stable current distribution and compatibility with the electrolyte.
How Metal Electrowinning Works
Copper Example
Metal electrowinning recovers dissolved metal ions through controlled electrodeposition. The cathode collects the target metal, while the anode supports the required anodic reaction under controlled current and electrolyte conditions.
Metal-Bearing Electrolyte Enters the Cell
The electrolyte contains dissolved metal ions such as copper, zinc, nickel, cobalt, or other recoverable metals.
Metal Ions Deposit at the Cathode
Metal ions are reduced and deposited onto the cathode or starter sheet under DC power.
The Anode Supports the Anodic Reaction
Titanium-based anodes support oxygen evolution or other anodic reactions depending on electrolyte chemistry and coating selection.
Process Conditions Control Performance
Cell voltage, current density, acidity, chloride content, temperature, and coating stability affect efficiency, energy use, and service life.
