Very educational. The moral of this story: don’t buy electronic scrap for refining. Hyperinflated prices, laughable yield. Only use that stuff if it was free.
Just when you think that processing trimmed fingers from electronics is a good way to make money, Sreetips goes to great expense to show you it isn’t. Thanks for the videos, sir.
Thanks for overpaying for the scraps to make the video. It was very educational. The gold looked very pure to my eyes. Better than the 22K gold coins I have. Most videos this long don't hpld my interest but this did. Seeing the acid fumes coming off the beaker reminded me of something that happened to one of my uncles. One of the fume hoods wasn't working and no one told him. When he opened the door and leaned in to get whatever it was out, he inhaled acid fumes that burned his lungs. Other than needing to use an inhaler the rest of his life because of the damage it caused, he seemed alright, but it ended his career in an instant. Acid fumes are no joke.
Agitation is the key. You need to get the fingers rubbing against themselves to break the foils loose. A single bubbler is too passive. You need an aggressive boil by using a tube with multiple air holes in the bottom with air pressure strong enough to move things around. Letting it just sit is like holding you hands in a sink hoping they come clean. You need to scrub them to get them clean. Your soak would likely have been only a few days not weeks. Also, recharge your acid as the reaction weakens the brew.
the reaction you are seeing that soon is from the solder on the finger boards. They should have been clipped closer to the edge, or resistors / Lead removed first. The seller should be ashamed of himself selling those boards for that much. It's like taking aluminum cans to the recycler filled with junk to increase the weight.
Love all your Videos I have learn so much from you I appreciate it much. I’ve been .refining 999 FS for a year now and refining gold as well. I’m a retired Disabled combat Army Veteran can no longer work but I finally found a great hobby thanks to you sir. Thanks you Sir I’ll continue watching your Videos. 👍👍👍
