Gold Fingers – How To Recover Gold From Electronic Scrap


In this video tutorial i’m showing how to recover gold from electronic circuit board scrap. Specifically the gold plating that is found on the board connector edge – A.K.A the “fingers”.
This video is a complementary to the complete written tutorial on Gold-N-Scrap website (direct link below)

The process applies to other kinds of gold plated itmes, given the substrate is unreactive (such as PCB, ceramic, glass etc’…). This process is less suitable for metallic items that are gold plated such as gold plated pins and gold filled items, though it will work with much effort and large consumption of acid.

Post a comment and let us know how much gold do you think this recovery process yielded.

    You don’t have to go through all of that crap. Go to the dollar plus store
    get a soldering iron. Heat the metal up with the iron and pry it up with a
    metal dental pick or exacto knife.

    Can this exact process be used for silver..? And if not, what would be the
    best way to extract the silver ? I found an unlimited supply of unused (but
    not up to quality control standards) PCB boards with silver. Thanks.
