Gold Recovery & Refining
Gold is a highly conductive, corrosion-proof precious metal recovered from electronic scrap, jewellery, and industrial residues. Viyanmani refines gold to 99.99% purity through proven chemical and electrolytic routes.
What is Gold?
Gold (Au, atomic number 79) is a dense, malleable, and virtually corrosion-proof precious metal with excellent electrical conductivity.
It is used in electronics connectors, jewellery, dentistry, and as a store of value, and it can be recycled indefinitely without any loss of quality.
Recovering gold from electronic scrap and manufacturing residues captures significant value while reducing the need for environmentally costly mining.
Industries using Gold
Gold applications
- Connectors, bonding wires, and plated contacts in electronics
- Fine and investment-grade jewellery
- Dental alloys and medical devices
- Aerospace and satellite thermal coatings
- Bullion and store-of-value products
Recovering and refining Gold
Our integrated route recovers Gold from secondary materials and refines it to 99.99% purity.
Recovery Process
Gold is recovered from printed circuit boards, connectors, plating solutions, jewellery scrap, and sweeps. Feed is sampled and assayed by XRF and fire assay to establish accurate gold content before processing.
Extraction Process
Gold is dissolved through selective leaching, then separated from base metals and other precious metals in solution, concentrating it for final refining.
Recycling Process
Because gold suffers no quality loss on recycling, secondary refining returns end-of-life gold seamlessly into new electronics and jewellery — one of the most efficient material loops in all of manufacturing.
Purification
Gold is purified by chemical precipitation or electrolytic (Wohlwill) refining to reach 99.99% purity, then cast into bars or grain and certified by assay.
Why refine Gold with Viyanmani
- 99.99% refined purity via chemical and electrolytic routes
- Accurate fire-assay and XRF valuation of complex feed
- Efficient recovery from low-grade electronic scrap
- Secure, insured handling and transparent settlement
Gold and sustainability
- Recycled gold avoids the severe land and water impacts of gold mining
- Eliminates the need for cyanide-intensive primary ore processing
- Captures value from e-waste that would otherwise be landfilled
Gold questions, answered
Common questions about how Gold is recovered, recycled, and refined.
Circuit boards, connectors, and plating residues are sampled and assayed, then gold is selectively leached into solution, separated from base and other precious metals, and refined chemically or electrolytically to 99.99% purity.
