Frequently Asked Questions
Answers about industrial gold, electronics, coatings and recycling.
Why is gold used in electronics if copper and silver conduct better?
Gold combines good conductivity with a surface that resists oxidation, making it useful at selected contacts and interfaces.
Is electronics the largest use of gold?
No. Jewelry remains much larger; electronics uses a smaller share for specialized functions.
Why are coatings thin?
A thin layer can provide the needed surface property while minimizing mass and cost.
Can electronics be recycled for gold?
Yes, through professional electronics-recycling and refining systems.
Does this site teach chemical gold extraction?
No. Hazardous extraction and refining procedures are excluded.
