Easy Gold Recovery From Fingers

[@richardhulbert9480]

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

[@LuisRodriguez-xf9lv]

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

[@Ken.Kaniff.From.Conn.]

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.

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

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

[@markgellie7032]

Nice I didn’t think you would get that much gold. I had the same thing happen with the copper sulfate crystals dropping out off solution. No big deal. They look nice though. Great video as usual I always get ideas from your videos 👍

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 ,

[@omegageek64]

It would have to be cheap because the NO2 fumes would destroy it in only a few hours. You wouldn't believe how destructive they are. I go through a lot of equipment.

[@Ghostontherun]

​@@omegageek64you could also get a fish tank bubbler, I was lucky enough to get one for a dollar at a garage sale

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!

[@markgellie7032]

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

[@thewhalsons7624]

Thanks Mike, another great video. 😊

[@sorcererstan]

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! 😆

[@briandiprose7468]

Once again you make learning entertaining, thanks

[@pappawheely]

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

[@scrapingE-wastebyMarsi]

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.

[@richardhulbert9480]

You've shown us how to make several hard to come by and sometimes illegal chemicals. Can you do a video showing us how to make that funny money next?

[@dannysearcy3373]

Awesome as always

[@afineliner740]

That was a great recovery. 👍

[@vw8796g35]

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?

[@omegageek64]

it should work.

[@shaneyork300]

Good yield Mike!!

[@محمداحمد-م9ل7ج]

طيب اذا كانت العينه تراب ايش من حمض تستخدم بالبدايه

[@mmm-p3j6n]

if distilled water is difficult to come by at times, would it be worth distilling your own water?

[@Alex-kp3hr]

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

[@Alex-kp3hr]

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

[@omegageek64]

Not for me. I don't have the storage space.

[@Alex-kp3hr]

I mean like nickel plated ribbon end connectors, nickel plated pins, nickel plated plugs and sockets, etc. The price of nickel is going up and for us scrappers its just like saving up enough of it until its worth refining like other metals.

[@Alex-kp3hr]

Lets say you are doing 2kg of trimmed fingers and go directly to nitric. You'll have a soup containing gold foils and dissolved copper, nickel. maybe tin and lead. Why not recover the nickel also?

[@me.bangladeshi]

Hello sir, For Gold precipitation in aqua regia, which SMB perfect, industrial or food grade

[@omegageek64]

I'm using industrial grade, and it works fine.

[@me.bangladeshi]

@@omegageek64 TNX a lot sir

[@markgellie7032]

Good video

[@GaiasPupil]

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

[@GaiasPupil]

Well after a few experiments last night, I think I'm just going to run them all in dilute nitric. The AP may have consumed the gold, the AR left what I thought was gold behind. So I'm kinda stumped. Think I'll just nitric the foils. It seemed to work without getting the double sided adhesive off.

[@omegageek64]

Try boiling them in a lye solution.

[@vw8796g35]

The time laps piano song😂😂😂

[@deanwilson2923]

boil fingers in water till flakes are free

[@Goody-l7i]

Peace be upon you or in your language. Welcome I am from Yemen and I have experience with this type of work that you work in, whether it is with damaged acids and the method of separating all the metals separately. Can I give you the experience? It is simple and effective.

[@rockycraft401]

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

[@omegageek64]

I've heard it can be done, but I've never tried it myself.

[@rockycraft401]

Happy Easter Mr Mike this is Rocky again I have a question about some sediment that I dropped out of nitric acid buy cementing with copper pipe going for silver but that is not what I got

[@rockycraft401]

Your advice or expertise would be appreciated I have pictures of the sediment if that would help you

[@abeleski]

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

[@timtoolman4125]

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

[@POOPY-c7w]

Can I do the same using sodium nitrate 15:46

[@omegageek64]

Should work fine.

[@AbdulRehman-e6c]

You are so funny.

لا اعتقد ان هذة الجرمات تجرج من هذه الكميه من المخلفات هذا خطاء لا يخرج هذا بالمناجم

[@richardhulbert9480]

You know your weighing the bag🤪

[@Goody-l7i]

hi

[@emersonbiggens1502]

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

[@omegageek64]

You are correct! Bad math. I forgot to multiply the result of the division by 100. That's what happens when you stay up too late editing video.

[@emersonbiggens1502]

Love your videos. I've never wanted to go very deep into gold recovery, but gold fingers seem like something I could do. I currently have about 3 pounds of them.

[@SomeGuyInSandy]

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