With it being the high grade like that I was thinking it would've had a higher yield than that! It was an awesome video!! Have a Great Day My Friend!!!
guess i need to get back at it , been layin around all winter and need to rebuild my work station since the ice storm tore it down for me , lost a jar full of cloroauric from plated ceramic dishes in the collapse , i'm guessing a couple grams of gold gone , been saving that jar for about 3 years . bummer
I just lost 16 grams of gold in aqua regia. The aqua regia was 25ml nitric acid added to 65ml hydrochloric acid. The various gold pieces melted in a half hour with no heat, way faster than i expected. The color was a dark sludge like emerald green. During the filter rinsing i added distilled water making a little more than double the volume in solution. Then I put about a tablespoon of sodium chloride to drop the silver first in case some silver was plated with gold. No silver dropped. Then I added 1.5 teaspoon of sulfamic acid (in place of urea prills) to denox, then I added 2 teaspoons sodium metabisufate. It changed to a clear transparent emerald green, then it went purple emerald green, then back to emerald green. The gold would not drop out. I was disappointed and confused. Either the nitric acid was too strong (ph percentage wise) or because I put a tablespoon of sodium chloride to drop the silver first. To neutralize the solution for safe disposal it was added to a 20 litre pail filled with 1/3 distilled water in case of over fizz and neutralized slowly incrementally with baking soda and stirring with a 5 foot 1/2" dowel to keep a safe distance away from the fumes and in case the fizz splashed out of the pail. It took an hour to neutralize! I used frequent ph test strips. The acid neutralizing experience was weird! Thank God for my very basic chemistry knowledge and caustious instinct. The acid atomizes into the air when it fizzes! At one point the brown dioxide fumes come out even when neutralizing watered aqua regia solution. This was ALL DONE OUTSIDE at an open spot, on a windy day! Thank God i wore rubber gloves, face shield over non vented goggles to protect the eyes, two sweater jackets, repeatedly held my breath when I added the baking soda then briefly stirred the solution, then distancing myself far away upwind to safely breath clean air. Repeating this till the solution was neutralized. The pungent bleach like odor was strong at times from 20 feet away down wind. I washed my clothes after i was done and bathed in water. The next day the minor exposed skin tingled. Folks THIS IS NOT FOR NOVICES or city dwellers with many nieghbors. ALWAYS LEARN THE SAFE PROCESSES WITH AN ATTENDING GUIDANCE OF AN EXPERIENCED PERSON! White fuming nitric acid is overkill its SERIOUS stuff and its for experienced person only. 50% nitric acid is fine for aqua regia. Store what you need outside, leaching nitric acid odor can make people feel sick! But I still love watching and learning from gold leaching videos. Peace and safe prosperity to everyone.
Only thing I would have done differently is a second or third acid bath when dissolving the pins and contacts, it would make the next steps cleaner and the aqua regia solution would be less green(typically from copper still in the solution) and its ends up with a much cleaner final product. From what I’ve come to understand, but still a nice little button
Dusan, have you ever tried to cupel the pins 1st, before you use the Nitric? I've always wonder if that will remove most of the metals, thus saving you Nitric.
Good job freind. I wish u succès. I Want just to aske u about paladium i cant find dmg in my country (morroco 🇲🇦). Can i use something elss for the precipetation. Thank u so much brother

Nice video. Your precious metal recovery skills are excellent. Your Englsh spelling skills, not so much. Here are a few corrections Subscribe / Aqua regia /removing .

They are some really nice relays there 👌
You are still the gold king.
Aw man. It looked so good in the beginning! Can't win them all I guess.

wow nice collection bro..
Отлично!!!
Ngl 1:20 looks like a great idea
nice gold point relays!
Dusan, have you ever tried to cupel the pins 1st, before you use the Nitric? I've always wonder if that will remove most of the metals, thus saving you Nitric.
I have a bunch of random pins to process, can I do them all with this process?
love your work bro
Do you check for palladium in a batch like this? How do you know it's there and how would you separate it?
Check with tin chloride and then if brown I think you then can drop with dmg. But u can also do a test with the dmg itself I suppose.
👍👍
? The pins are just gold plated right? ?? Gold plated steel? ?
Hey Dussan can you explain me about SMB
metabisulfite de soude
I started saving up my scraps and 1 day, 1day ima try it out, ggz bruv
Friggin Aaaaaaaa!!!!!! 👍👍👍👍👍
Nice one 👍🏿
how can I contact you sir?do u know someone who buy palladium ?
Thumbs UP
hit gold bead flat with hammer if it cracks its not pure fun fact
You are nice video
Kaltube below, maybe you could make a video in his language for him. Don't look a gift horse in the mouth, get scrappin.
what are you using to make your charm plug?

Siftli nmrtk watsap akhay ndwiw ok
Hebat lo bro salut aku
Lotsof plastic on those kind of pins .

Yeah probably because he’s Serbian and not from an English speaking country 😂
