BIG NO NO, DO CUT THE PIN, the steel piece you see is separate from the gold pin, under that is still gold plating, looking inside you will see, common mistake
One last word of advice. From a guy who's been doing this about 12 years. If you have to buy electronic stuff for gold recovery, like on ebay. Don't, you will loose your shirt. I work with a salvage company, I get everything for free and split the recovery. Just picked up about 30 lbs of gold plated pins. Might be 2, 3 or even 6 months before I see any more. I look at ebay and I'm blown away by the prices. Don't be a sucker, it's not worht what they want. Not even close. You can easily spen 100 and only get 10.
you will lose a fair amount of flash plated gold using coffee filters , let your filtered solution sit for a couple days and you will see it settle on the bottom as a black film , decant and process that as well
try using sulfuric acid dilluted 50% with distilled water and sodium nitrate , go slow with the nitrate , its faster and fairly cheap , use heat on the thicker pins
Why everyone still uses peroxide beats me. Y'all know it does dissolve some of your gold. Use only half and low heat. Or in sun but takes away longer. Or just add half old ap and half fresh muriatic acid. Still great video
I was curious about the fact that you were getting a nice amount of product .After watching a 1/2 dozen of scraping gold from electronic’s . Okay I’ll just have to say you started with nice pins and prices. I liked your video the best, the clock was a nice touch. I myself like to tinker and in the past couple years I have about ten pounds of which I would like to say is quality I use mostly for repair and innovation adapting parts for my entertainment also. So I was thinking of selling off some of my stuff, I came across videos using the different process’s. I just don’t know if I want to part with my parts unless the price goes up or, And getting the most out of all the work. I’d like to give it a try one day.
Good observation! The true answer is I decided at the end of the first day to double the amount, at the same ratio. My hope was to speed up the process, but I don't think I really gained much time by using the extra acid solution, likely just a waste. Thanks for watching.
