Group 1 - The core advantage of ruthenium-iridium-titanium mesh lies in its role as a dimensionally stable anode (DSA), making it indispensable in three key industries [2] - In the chlor-alkali industry, ruthenium-iridium-titanium mesh acts as the anode in electrolysis, converting brine into chlorine gas, hydrogen, and caustic soda, with a lifespan of 3-5 years under harsh conditions [4] - In the renewable energy sector, this mesh is crucial for hydrogen production through water electrolysis, significantly reducing energy consumption and contributing to carbon emission reductions [5] Group 2 - The ruthenium-iridium-titanium mesh has three layers of value when recycled: the precious metal coating, the titanium substrate, and environmental benefits from reduced mining impact [7] - The precious metal coating contains approximately 60%-70% iridium and 30%-40% ruthenium, with a market value of 3000 RMB per gram for iridium and 60 RMB per gram for ruthenium [8] - The titanium substrate, with a purity of over 99.5%, can be recycled and reused, with a recovery price of 50-80 RMB per kilogram [9] Group 3 - The pricing for recycling ruthenium-iridium-titanium mesh is determined by four key factors: coating residue, titanium weight and condition, market prices, and processing costs [10] - The coating residue is assessed using spectral detection, which directly influences the value of the old mesh [11] - Market fluctuations, particularly in iridium prices, can significantly impact the recycling price, with historical peaks affecting potential returns [12]

Group 1 - Ruthenium-iridium-titanium mesh is penetrating the new energy and chemical industries, acting as an "industrial vitamin" due to its exceptional corrosion resistance and conductivity [1] - In a domestic chlor-alkali enterprise, the ruthenium-iridium-titanium mesh anode has a lifespan of 8 years, which is 300% longer than traditional graphite electrodes, and reduces the electricity consumption for producing caustic soda by 15% [1] - The recycling market is experiencing a significant value transformation, with the price of used mesh materials showing a notable gradient, reaching 820 RMB/kg for materials containing 15g/m² of ruthenium and 5g/m² of iridium [1] Group 2 - Traditional pyrometallurgical recovery has a recovery rate of only 70%, while a leading company has improved ruthenium recovery to 92% and iridium purity to 99.95% using a "microwave digestion-ion exchange" technology [3] - The demand for ruthenium-based catalysts is expected to reach 220 tons/year by 2030 due to the global hydrogen energy strategy, creating a tight supply-demand balance that increases the recycling value of used ruthenium-iridium-titanium mesh [3] - The comprehensive recovery rate of ruthenium and iridium from recycled mesh materials has increased by 18 percentage points from 2020, directly boosting the gross profit margin of a recycling company to over 35% [3] Group 3 - The dual revolution in materials and resources is constructing a closed-loop value chain, where front-end applications drive industry upgrades and back-end recycling ensures resource security [6] - Establishing a graded management system for waste mesh materials and utilizing rapid detection technologies can maximize recycling value for waste-producing enterprises [6] - Advanced technologies like supercritical CO₂ extraction are key for recyclers to break through industry homogenization in the context of increasingly scarce precious metal resources [6]
