Gold & precious
Precious metals in circuit boards are thin coatings and tiny contacts. Recovering them safely means grading, concentrating and refining under controlled conditions. It never means acid baths or open burning.
01 · In
A circuit board
Graded high, medium or low by its precious-metal content.
02 · Depopulated
Components come off first
Batteries, heat sinks and large parts are removed by hand.
03 · Concentrated
Gold contacts and pins gathered
Edge fingers, leads and pins carry the gold.
04 · Refined
Back to gold
Recovered in a controlled, assayed process. Never acid baths or open burning.
Step by step
From what arrives
to what leaves
- 01
Grading
Boards are sorted into high, medium and low grade by type, since precious-metal content varies widely.
- Equipment
- Sorting benches, reference library
- Principle
- Phone and server boards are richer than power-supply or TV boards.
- Output
- Graded board lots
- 02
Depopulation
Batteries, heat sinks, steel brackets, large capacitors and cables are removed by hand first.
- Equipment
- Dismantling benches
- Principle
- Removes hazards and dilution before any processing.
- Output
- Clean boards + separated components
- 03
Size reduction
Boards are shredded and milled into fine particles under dust extraction.
- Equipment
- Shredder, hammer mill, dust collection
- Principle
- Freeing the metal from the glass-fibre substrate.
- Output
- Board powder
- 04
Physical separation
Magnets pull out steel, eddy currents eject aluminium, and density or electrostatic separation splits the metal concentrate from the fibre and resin.
- Equipment
- Magnetic, eddy-current & electrostatic separators
- Principle
- Each material responds differently to magnetism, induced currents and charge.
- Output
- Metal concentrate + non-metal fraction
- 05
Controlled refining
The concentrate is refined with emission controls: smelted so copper collects the precious metals, then electro-refined, or chemically processed in a closed system.
- Equipment
- Certified refinery processes
- Principle
- Precious metals concentrate in the copper and in the residues of electrolytic refining.
- Output
- Gold, silver, palladium, copper, tin
- 06
Assay & settlement
Precious-metal content is measured by assay, so pricing is based on what was actually recovered.
- Equipment
- Fire assay / XRF
- Principle
- Measured content, not guesswork.
- Output
- Assay report
Safety first
No burning. No acid baths. No shortcuts.
Informal recycling burns cables and dissolves boards in open acid, harming workers and neighbourhoods and wasting most of the metal. Every stage here is mechanical, controlled or done by certified refiners, and every load is weighed and documented.
