The economic value of iridium recycling stems from the metal's extreme scarcity and irreplaceable industrial applications. With global annual production at only about 7-8 tons and the price per gram exceeding $6,000, iridium recycling stands as the premier segment in high-value metal recovery. Data from the American Precious Metals Institute indicates that raw material costs for specialized iridium recyclers account for less than 15% of output value—significantly lower than the 40% cost share associated with primary ore mining. Practice at BASF's chemical plants in Germany demonstrates that catalyst materials obtained through iridium recycling exhibit identical service life to new materials while reducing costs by 62%. Tanaka Kikinzoku's annual report reveals its iridium recycling business contributes 38% of the company's precious metals division profit margin, significantly outpacing other metal recycling operations. These figures confirm that iridium recycling is not only the reuse of scarce resources but also a commercial activity with exceptionally high investment returns. Particularly in aerospace, recycled high-purity iridium is used to manufacture engine ignition systems, fully meeting extreme environmental performance requirements and maximizing resource value.
Current iridium recycling techniques have evolved from traditional chemical extraction to molecular-level precision recycling. ULTRA Metals' combined ion exchange-electrochemical refining process achieves a 99.2% recovery rate for iridium from waste materials, with purity reaching 99.995%. The vacuum pyrolysis technology adopted by CERN can separate 99.98% high-purity iridium from composite metal waste, making it particularly suitable for processing iridium alloy components in particle accelerators. Germany's Heraeus Group pioneered supercritical fluid extraction technology, utilizing carbon dioxide under specific temperature and pressure conditions to efficiently recover trace amounts of iridium from medical devices. This method reduces recovery costs by 45% compared to traditional approaches. These technological advancements have expanded iridium recovery beyond high-concentration waste streams, making low-concentration sources such as electroplating waste liquids and precious metal catalysts residues viable recovery options.
The global iridium alloy manufacturing sector is dominated by three companies: Johnson Matthey of the UK, Shaanxi Sanyi Yuyan Materials Technology Co., Ltd. of China, and Furuya Metal of Japan. Johnson Matthey commands 60% of the aerospace market with its patented iridium-rhodium alloy technology. Its Ir-192 alloy maintains superior mechanical properties at temperatures up to 2100°C, finding extensive use in rocket nozzles and aircraft engine ignition systems. The company operates a proprietary iridium recycling system, recovering metal from end-of-life aerospace components to meet 35% of its raw material needs, thereby establishing a fully closed-loop supply chain.
Japan's Furuya Metal specializes in iridium-tungsten alloys for the electronics industry. Its high-reliability contact materials achieve lifespans exceeding 1 million cycles, primarily supplying 5G base station filters and semiconductor manufacturing equipment. The company developed proprietary chemical extraction processes to recover iridium-tungsten alloys from electronic waste, achieving 99.97% purity. China's Sanyi Youyan, Asia's leading iridium crucible manufacturer, has overcome technical barriers to produce 450mm super-large crucibles. Its products are internationally recognized as significantly surpassing comparable Japanese and British offerings. The company also engages in iridium recycling and purification, employing a combined vacuum distillation-electrolytic refining process to elevate recycled iridium purity to 99.99%, enabling direct use in new crucible production. All three enterprises have established integrated systems for iridium recycling and product manufacturing. At Johnson Matthey, the iridium recycling business contributes 38% of the company's precious metals segment profit margin, demonstrating the cost optimization value of iridium recycling for high-end manufacturing.
Although a few large titanium alloy/coating manufacturers operate their own titanium recycling plants, they possess a critical weakness compared to specialized precious metal recyclers: they cannot meet the volume and pricing demands of small-to-medium-sized iridium recyclers.

Industrial iridium recycling has established a comprehensive circular ecosystem. In aerospace, iridium alloys from engine ignition systems undergo specialized recycling for reuse in new components, achieving material-level circularity. In the chemical industry, iridium platinum catalysts achieve 98% activity recovery after regeneration. BASF reduces its annual new iridium procurement by 120 kilograms through recycling. The electronics manufacturing sector recycles spent iridium sputtering targets, producing new targets that fully meet semiconductor manufacturing requirements. The medical sector employs specialized recycling and processing for radioactive iridium-192, simultaneously addressing nuclear safety concerns and enabling resource reuse. This industrial recycling model not only ensures the sustainable utilization of iridium resources but also establishes a stable supply chain system, making niobium recycling an indispensable component of high-tech industries.
