Titanium‑Based Anodes for Non‑Ferrous Metal Electrowinning

Hydrometallurgy extracts non‑ferrous metals via electrolytic electrowinning from liquid electrolyte. Typical electrolyte systems include chloride solutions, sulfate solutions, and mixed chloride‑sulfate solutions.

Traditional anode materials such as graphite and lead alloys present obvious drawbacks in real‑world operations. They suffer from material dissolution, dimensional deformation and generate secondary pollution, which cannot satisfy today’s stringent environmental‑protection requirements. Titanium‑based noble‑metal oxide anodes have become a reliable alternative for modern hydrometallurgical processes.

Typical Application & Our Product Offerings

Based on long‑term R&D and field‑service experience, we manufacture high‑performance titanium anodes for copper electrowinning, nickel electrowinning, cobalt electrowinning and other non‑ferrous metal recovery under harsh electrolytic conditions.

Our titanium‑substrate lead‑dioxide electrodes adopt a multi‑layer three‑dimensional composite coating structure (noble‑metal oxide intermediate layer + α‑PbO₂ + β‑PbO₂). This layered design significantly enhances coating‑to‑substrate bonding strength.

 Key Performance Advantages

-Low electrical resistivity and excellent conductivity, supporting high‑current‑density operation

-Stable chemical performance in complex chloride‑sulfate electrolyte environments

-Outstanding corrosion resistance, reduces electrode consumption and impurity contamination of metal products

-Strong coating adhesion, mitigating coating peeling and extending service life

We are also continuously developing and validating custom mixed‑metal‑oxide (MMO) anodes tailored for diverse hydrometallurgical workflows.

Custom substrate shapes, coating formulations and dimensions can be provided to match your electrolyte and process parameters.
