Rhodium recycling is critically important due to this metal’s irreplaceable role in automotive exhaust catalysts, chemical manufacturing, electronics, and high-temperature alloys. As a scarce precious metal, efficient rhodium recovery technologies are essential for sustainable industrial operations.
What is Rhodium?
Rhodium is a silvery-white precious metal with an ultra-high melting point (1964°C) and exceptional corrosion resistance. Chemically stable, it resists acid reactions but interacts with oxygen/halogens at high temperatures. Its standout catalytic performance – particularly in redox reactions – makes it invaluable.
Key Applications
1. Automotive Exhaust Catalysts
As a core component in Three-Way Catalysts (TWCs), rhodium converts toxic gases (CO, NOx) into harmless substances.
2. Chemical Catalysts
Vital for organic synthesis, hydrogenation, and carbonylation reactions.
3. Electronics
Enables high-precision resistors, electrodes, and optical coatings.
4. High-Temperature Alloys
Enhances oxidation resistance in jet engines and industrial turbines.
Rhodium’s scarcity and high cost (3x gold price) necessitate advanced recovery solutions.
Primary Rhodium Recycling Sources
1. From Ores
Rhodium coexists with platinum/palladium. Centrifugal extraction technology achieves 99.2% separation efficiency vs. traditional methods’ 75-85%.
2. From Spent Catalysts
Auto catalysts contain 0.1-0.3% rhodium. Our technology extracts >98% pure rhodium from leachates.
3. From Industrial Wastewater
Recovers trace rhodium (0.001-0.005%) from electronics/chemical effluents, boosting resource utilization by 30x.
