Easy Gold Recovery From Fingers  

So I mimicked your process and though I had a bit more material it turned out well. It may not be a lot to some but I added 3.87 grams to my bottle. Was my biggest drop so far. Wanted to say thanks for making it seem simple for the dummies. Not that I would consider myself one but my wife sure would

Excellent video. I just ran my PC fingers that I've collected for the last few years. It was my first gold refine ever. I ended up with a 1.8g button. I forget the exact weight of the fingers but it was a little over a pound to begin with. Maybe 1.5 lbs or so.

I have melted finger foils many times. It comes in at 18k pretty consistently, that's under Xray. Mostly nickle contamination with a hint of copper

Hi Mike, Another awesome video by a wonderful teacher! Very easy to understand & follow! Thank you for your time & expertise! Thumbs up!! Safety first! Jim

Nice results! Those fingers looked like so much gold in the bowl, I would have been tempted to just put those in something as-is for display! 😆

Once again you make learning entertaining, thanks

As a suggestion from an engineer , why not get a cheap ultrasonic cleaner and use that to process these , it's stainless and heats to a controlled temp , and inputs significant energy in the form of vibrations , as the acid is diluted in water the cavitation will continually agitate the fluid to surface film , and hasten the reaction basically unattended ,

Thanks Mike, another great video. 😊

I had the same thing happen with the copper sulfate dropping out off solution looks great. I didn’t think you would get that much gold. Thank you I always get good ideas from your videos

I don't remember who it was otherwise I would give credit where credit is due, but for rinsing the released foils off the fingers, he used a jar with holes in the lid big enough to let the foils fall out but not the fingers. First, he filtered the solution. Then he would put some fingers and filtered solution in the jar, screw on the lid, and agitate or shake it and then the let the solution and foils drain through the holes in the lid and into the filter. If needed, he would use the re-filtered solution and repeat until all foils were rinsed off all the fingers. He then stored the non-diluted solution for reuse with a new batch of fingers and then used distilled water to wash off the foils in the filter. Seems like a good way to keep your original solution from being diluted if you're going to reuse it, you use less water which saves you money if you use distilled water, you end up with less waste liquid, and you're not going through and handling each piece one by one. Granted you'll have the filter paper to deal with, but maybe it's a small price to pay overall. For context, I believe he used a copper something (chlorate/sulfate/chloride/I don't remember) solution to release the foils that he reused multiple times for multiple batches of fingers. Looking forward to your next video. Thank you! (EDIT) Thinking about it more, he may have stored the first filtered solution, used saved dirty water from previous final rinses in the jar, then did a final rinse of the foils and filter with clean water which then was added to the water from previous final rinses for reuse. That way he had very little to no waste liquid to deal with. Wish I could remember for sure. It seems like either way would work. Thoughts or comments? Would that work regardless of what solution is being used to release the foils, i.e straight hydrochloric acid, Acid Peroxide solution, dilute nitric, poor man's nitric, copper whichever-it-is (chlorate/sulfate/chloride)? Thank you again!

A fish tank bubbler would add some agitation to the pot you think ? nice demo thank you...

Great work. My support and like. All the best from Serbia. I collect a bunch of materials thry 5.yrs of SCRAP and I still goth all stuf. Keep the good work.

I checked and no one said it so here it goes...you know you also weighed the bags along with the fingers right😂? Cant believe how much gold you got. I was thinking 0.8gr

The time laps piano song😂😂😂

very well explained video for lerners like me. i apreciate to se the same with plated pins. keep that good work

That was a great recovery. 👍

Good yield Mike!!

Hi this is definitly faster then copper chloride and less liquid waste !!. Thank you for this idea. 😃 As you put a lot of water can we use dilute sulfuric acid some water and potassium nitrate?

Good video

HEY Mike! Grats on your 20k milestone again! May I ask for 2 minutes of your time? See my post yesterday that's 2 minutes long and maybe you can help me out with the double sided adhesive! Thankyou kindly

You are so funny.

At 13:00 you turn up the heat just a tad. Would adding a bubbler at this point help at all? Cheers

You know your weighing the bag🤪

Looks like it is time for another fume hood fan replacement video.

boil fingers in water till flakes are free

Hi Mike, When scraping pc boards, is it worth in the long run to hold on to nickel plated items?

My name is Rocky live in Texas I was wondering is it possible to retrieve silver from CDs and DVDs

As sreettips pulls nails on a chalkboard back in his lab...

Can I do the same using sodium nitrate 15:46

Sreetips would have dumped all the chemicals into that beaker! Accelerate!

Wouldn't it be 0.41% ? Not .0041%
