DSA (Dimensionally Stable Anodes) widely used in the chlor-alkali industry feature a titanium metal substrate coated with an active layer of precious metal oxides (e.g., ruthenium oxide, iridium oxide). After use, these anodes retain substantial recoverable precious metals.
MMO anodes (precious metal oxide anodes) used in water treatment facilities contain precious metals like iridium and ruthenium, making them a key material for our precious metal recovery operations. Titanium-based precious metal electrodes in seawater electrolysis require periodic replacement due to prolonged exposure to corrosive environments, providing a stable feedstock source for precious metal recyclers. Precious metal catalysts used in electrochemical oxidation processes primarily contain elements such as Pt, Ir, Pd, Ru, and Rh, possessing extremely high recovery value.
Specialty precious metal catalysts and electrode materials in aerospace, precious metal components in medical devices, reactor linings and catalysts in chemical equipment, anti-corrosion anode systems in shipbuilding, automotive catalytic converters, precious metal powders for 3D printing, and precious metal products involved in international logistics transportation are all key areas of focus for our precious metal recycling company. Through specialized precious metal recovery processes, waste materials from these sectors enable efficient resource recycling.
The recovery and utilization of industrial precious metal waste is a technology-intensive endeavor requiring specialized knowledge and equipment from recyclers. Precious metal waste from different industries possesses unique characteristics and recovery value, necessitating differentiated processing approaches.
Precious metal catalyst recycling constitutes a vital segment of our operations. These materials typically contain precious metals such as Pt, Ir, Pd, Ru, and Rh, possessing exceptionally high recovery value. Platinum (Pt) exhibits outstanding hydrogen evolution performance, with the free energy of its hydrogen adsorption intermediates approaching the ideal value of zero, thereby achieving the highest catalytic activity. Industrial water electrolysis predominantly uses Pt/C as the hydrogen evolution catalyst, with many HER catalyst studies benchmarked against Pt/C performance. IrO₂ and RuO₂ are commercial oxygen evolution catalysts and serve as reference points for numerous investigations.
Titanium anode recycling focuses on DSA (dimensionally stable anodes) from electroplating tanks in plating facilities. These anodes feature a titanium metal substrate coated with an active layer of precious metal oxides, retaining substantial recoverable precious metals after use. Recovery of MMO anodes (metal oxide precious metal anodes) primarily targets applications in cathodic protection systems. Such anodes are coated with precious metal oxides like iridium or ruthenium, combining high conductivity with strong corrosion resistance.
