Is it possible that you still had some gold in solution? Because of the yellow color of the solution the other day.

Could you also dissolve gold in HCl by just adding concentrated H2O2 ? 🤔😕

I respect you.

Good👍

The first song what is the name!?? good video

Which metal vessel will be suitable for heating sulfuric acid, Nitric acid. I am confused. I searched a lot of videos but not solved. love from INDIA❤❤

Sir Which Pot Do use For Sulfuric Acid

Metal scrap also we can recover ?

Buy the acid more expensive then get the gold

Only thing I'm unsure of is where do I get sodium metabisulfite

Nice components, sir! Score! Peace Prospector Tripp

You are amazing, thank you.

Gold aveleble all blue quqrtz????

Were they all the same one? With gold bonding wires? That looked too easy without crushing 😂 good show man!

Good video 🤑

Nice one. So the yield is less than 10 grams per kg!!?

Thanky you sir ., good job😊

احسنت هذا جيد لدي سؤال هل سماد اليوريا يعتبر من النترات

Is using a cotton cloth substitute for synthetic tissue fiber okay? Or its gonna get dissolved?

2:31 does it worth any thing? I mean the beryllium graphite iron, I have about 20 kg for same material

Good one

I thought those were called Mosfets?

Sir, cell phone circuit board and any pcb board this method use recavery gold. Any toilet cleaner use?

Can I use Tincture Iodine 2.4%?

doing gold recovery from old cpu processors on a large scale is profitable so why don't many people do it??

Dear sir, if gold is in powder ( DUST ) form, can it be dissolved in nitric acid?

Thanks for this video. What do you use for mask if needed? When I'm outdoor I use a fan to blow the strong fumes away from me, only when I'm working with the solutions. It helps. Windy days are good too.

Please tell me using what chemical water

Ofcourse you could put the SMB in some distilled water and boil it and then put it in your gold solution.

Is it possible from toilet harpick

From Aceh indonesia👍oke master..

Man i have a way that removes it a lot faster than that an it works u just need to stay with it use one cup hydrogen peroxide and 2 tablespoon Mariah acid and it will remove your gold in 2 hours u just have to stay with it or it will turn to liqued if it dose that then u will have to use aqua regia

What do you use for the toxic fumes? Very much interested in doing this, but the acid-digesting hoods are quite pricey... is there another way that doesn't require me to harvest my own kidney or sell myself into slavery to pay for it?

Excellent.!

First mechanical separation and concentration. Next digest the concentrates with diluted sulfuric acid. Next filter off and rince 2x with boiling hot distilled water. Then take the solids and digest with nitric acid, copper silver and palladium disolve. Gold wont. Filter out the gold and crap mixtur from your copper silver pd acid mix. Make a solution of 5 parts HCl to 1 part HNO3. This will disolve gold and platinum. The remaining precipitates are garbage if e waste is your pm source. To get the gold process multipld batches till your aqua regia will hold no more. Then filter and put into a flask. Add dropwise ammonia till the cloud of precipitation disappears. Let this settle as its s mix of Pt and Pd NH2/Cl2 complex. Filter off the yellow solution of HAuCl4 and distill off excess acids. Keep going till it starts getting slightly cloudy and cool. The crystals you get are chloroauric acid. Save these as they can be used as feed stock for an electrochemical refinement cell. Did a lot of gold refining from scrap back in the later 90s and early 2000s when chemicals didnt cost a fortuine and rewuire you to sell your soul to buy them.😂

1. regal water is used not to melt the gold, but to raise its setting. 2.SnCl2 is not required for gold detection in liquid

Anyone will put solder in Aqua regia you wont get any gold from it. not at all!!!
