High-performance surface treatments engineered to withstand high current densities and corrosive acid mist in hydrometallurgical operations.
The Democratic Republic of Congo (DRC) is globally recognized as the epicenter of the green energy transition, harboring over 70% of the world's cobalt reserves and massive reserves of high-grade copper. Mining complexes across Kolwezi, Likasi, and Lubumbashi are expanding rapidly. However, the processing of these essential metals presents extreme metallurgical challenges.
Traditional electrowinning and acid-leaching circuits rely heavily on lead-alloy anodes. These legacy components suffer from rapid degradation, contaminating copper cathodes with lead particles and generating hazardous sulfuric acid mist. By transitioning to Dimensionally Stable Anodes (DSA)—comprising grade 1 titanium substrates coated with advanced mixed metal oxides (MMO) like Ruthenium-Iridium (Ru-Ir) and Iridium-Tantalum (Ir-Ta)—DRC smelting operations can realize unmatched processing efficiency, energy reduction, and cathode purity.
Bridging premium raw material sourcing with advanced electrochemical engineering to deliver high-performance coated metals to African mining basins.
As heavy industry shifts toward decarbonization and strict ESG directives, traditional electrowinning processes are undergoing rapid upgrades. Lead and iron anode technologies are being replaced globally by Platinum-coated and MMO-coated titanium substrates. These modern components improve current efficiency and prevent hazardous heavy metal sludge production.
Our state-of-the-art Chinese manufacturing facilities leverage deep vertical integration, from raw titanium powder processing to automated thermal decomposition coating lines. This enables us to maintain tight control over substrate purity and coating thickness uniformity, while keeping lead times significantly shorter than Western suppliers.
Drawing on decades of experience in high-performance metallurgy, our materials are manufactured in compliance with ASTM B265, ASTM B348, and ISO 13485 standards. We utilize scanning electron microscopy (SEM) and X-ray diffraction (XRD) testing to verify chemical homogeneity, ensuring long-term reliability under severe working conditions.
Understanding the electrochemical mechanisms that make titanium and stainless steel corrosion-resistant and highly catalytic.
Designed primarily for chlorine evolution reactions. Ideal for seawater electrolysis, chlor-alkali production, and salt chlorination systems. They offer low chlorine overpotentials and strong mechanical adhesion.
Engineered specifically for oxygen evolution in highly acidic environments (sulfuric acid systems). Widely used in hydrometallurgical copper/cobalt electrowinning, electroplating, and foil manufacturing.
Provides excellent corrosion protection and durability in mixed halide electrolytes. Commonly used in hard chrome plating, organic synthesis, and hydrogen generation electrolyzers.
Engineered solutions designed for the challenging operational environments of Central Africa.
Our Ir-Ta coated titanium plates serve as low-maintenance anodes in sulfuric acid electrowinning tanks. They generate high-purity copper and cobalt cathodes while minimizing lead contamination, helping mines meet international compliance standards.
Corrosive soils and mineralized groundwater in central African operations require active corrosion mitigation. MMO titanium ribbon anodes and cathodic protection wires safeguard buried fuel lines, mining pipelines, and structural foundations.
For tailing processing and industrial wastewater reclamation, our Ruthenium-Iridium coated titanium meshes enable efficient electrochemical purification and heavy-metal extraction, supporting environmental regulatory compliance.
