Platinum Recovery & Refining
Platinum is a dense, corrosion-resistant Platinum Group Metal prized for its catalytic activity, chemical stability, and high melting point. Viyanmani recovers platinum from spent autocatalysts, chemical process catalysts, and electronic assemblies to purities exceeding 99.95%.
What is Platinum?
Platinum (Pt, atomic number 78) is a silvery-white Platinum Group Metal (PGM) with exceptional resistance to corrosion, oxidation, and chemical attack.
Its high melting point of 1,768 °C and outstanding catalytic activity make it indispensable to emissions control, hydrogen technologies, and fine chemical synthesis.
Because primary platinum mining is energy-intensive and geographically concentrated, recovering platinum from end-of-life materials is central to a secure, circular metals supply.

Recovering and refining Platinum
Our integrated route recovers Platinum from secondary materials and refines it to 99.95%+ purity.
Recovery Process
Recovery begins with precise sampling and X-ray fluorescence assay of incoming spent catalysts and scrap. Platinum-bearing feed is homogenized, then processed through a smelting collection step that concentrates PGMs into a metallic phase, separating them from ceramic and refractory carriers.
Extraction Process
Concentrated platinum is dissolved in aqua regia, taking the metal into solution as chloroplatinic acid. Base metals and unwanted elements are removed through controlled chemistry so that only the target PGM fraction advances to refining.
Recycling Process
Viyanmani's closed-loop recycling route returns platinum from autocatalysts, process catalysts, and electronic scrap back into industrial-grade sponge and salts — displacing freshly mined metal and dramatically lowering the embodied carbon of every gram recovered.
Purification
Selective precipitation and solvent extraction isolate platinum from palladium, rhodium, and other PGMs. The purified platinum salt is calcined and reduced to sponge, then verified by ICP-OES to guarantee 99.95%+ purity.
Why refine Platinum with Viyanmani
- Purity of 99.95% or higher, verified by ICP-OES analysis
- Full material traceability from intake assay to final settlement
- Competitive, transparent metal-value returns
- Secure, insured handling of high-value consignments
Platinum and sustainability
- Recycled platinum carries a fraction of the carbon footprint of mined metal
- Avoids the land disturbance and tailings associated with primary extraction
- Keeps a finite, strategically critical resource in productive circulation
Platinum questions, answered
Common questions about how Platinum is recovered, recycled, and refined.
Spent converters are crushed and sampled, then the ceramic honeycomb is processed through pyrometallurgical smelting that collects platinum and other PGMs into a metal phase. The concentrate is dissolved and refined chemically to isolate high-purity platinum sponge.
