Who We Are
A precious-metal refiner built on precision, trust, and sustainability
Viyanmani recovers platinum, palladium, rhodium, ruthenium, iridium, gold, and silver from spent catalysts, electronic scrap, and industrial residues. By combining pyrometallurgy and hydrometallurgy, we return high-purity metal to industry — and keep critical resources in circulation.
- Integrated smelting and chemical refining under one roof
- Transparent, assay-based valuation and certified purity
- A genuine circular-economy alternative to primary mining
What We Do
All ServicesEnd-to-end precious-metal recovery services
From catalyst recycling to high-purity PGM refining, we cover the full lifecycle of precious-metal recovery.
PGM Refining
High-purity refining of all six Platinum Group Metals, to up to 99.95%+ purity.

Seven precious metals, refined to the highest purity
Dedicated, technically detailed guidance on every metal we recover — from the six Platinum Group Metals to gold and silver.
Why Viyanmani
The refining partner industry trusts
Technical capability, transparency, and sustainability come together in every consignment we handle.
Integrated Pyro & Hydrometallurgy
Combining high-temperature smelting with precise wet chemistry lets us recover metal from feeds that single-route refiners cannot process efficiently.
Certified High-Purity Output
Every refined lot is verified by ICP-OES and shipped with a certificate of analysis documenting the purity achieved — up to 99.95%+ for Platinum Group Metals, subject to feed material.
Transparent Settlement
Clear, assay-based valuation and full traceability from intake to payout mean you always know exactly how your metal value was determined.
Secure, Insured Handling
High-value consignments are protected by insured logistics, secure processing facilities, and documented chain-of-custody controls.
Sustainability by Design
Our closed-loop model returns critical metals to industry with a fraction of the carbon footprint of primary mining.
Expert Metallurgical Support
Experienced metallurgists advise on material preparation, sampling, and logistics to maximize the value recovered from your streams.
Our Recovery Process
From spent material to refined, certified metal
A rigorous 12-step process combining inspection, assay, pyrometallurgy, hydrometallurgy, and precise chemical separation.
1
Material Collection
Secure intake of precious-metal-bearing feed from across industry, with insured logistics and documented chain of custody.
2
Material Inspection
Incoming consignments are weighed, visually inspected, and classified by material type to determine the optimal processing route.
3
Sampling
Representative sampling ensures accurate valuation. Heterogeneous feeds are homogenized so every assay reflects the true metal content.
4
Chemical Analysis
Samples are assayed by XRF, ICP-OES, and fire assay to precisely quantify platinum, palladium, rhodium, gold, silver, and other values.
5
Pyrometallurgical Treatment
High-temperature smelting collects Platinum Group Metals into a concentrated metallic phase, separating them from ceramic and refractory carriers.
6
Hydrometallurgical Processing
The metal concentrate is dissolved through controlled leaching, bringing precious metals into solution for selective separation.
7
Chemical Separation
Dissolved metals are separated from one another and from base-metal impurities using precise, sequential separation chemistry.
8
Individual Metal Separation
Each precious metal is isolated into its own high-purity stream, ready for final refining to fine metal.
Industries We Serve
All IndustriesTrusted across the industrial economy
We recover precious metals for the sectors that depend on them most.
Sustainability
Every gram recovered is a gram not mined
Precious-metal recycling uses a fraction of the energy of primary extraction and avoids the land, water, and carbon impacts of mining. Our closed-loop model is built for a circular economy.
