WARNING!!! This must be done outdoors or under a fume hood! Acids are dangerous! There are warnigs throughout the video, please heed them! This project was only in my garage for about 20 minutes for filming purposes! Gold recovery from gold fingers and gold plated boards using the A/P method or Acid peroxide is in my opinion the best way to get started in gold recovery. If done safely, this is a very fun hobby! Using Muriatic acid and hydrogen peroxide, you can dissolve the copper and nickel etching that holds the gold foils to most boards. Make sure the boards are free of other materials first though!
