- Gold recovery from Aqua Regia Acid Use zinc powder.@MakeGold
Aqua regia is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. Aqua regia is a yellow-orange (sometimes red) fuming liquid, so named by alchemists because it can dissolve the noble metals gold and platinum, though not all metals.
Aqua regia is primarily used to produce chloroauric acid, the electrolyte in the Wohlwill process for refining the highest quality (99.999%) gold.
What did u do with the bulk sediment before using zinc..it only shows in process the sediment from the sync powder...or is this video only to show how to get back remaining gold sediment left in aqua regia
Hello, and thank you for this video. I learned from him. I have a question: Did the zinc powder deposit copper with gold upon precipitation and got a lot of copper?
Very good for high gold content 👍
Sir, which one is more effective for precipitation, by zinc powder or SMB? In case of by using zinc powder, shall it be boiled? Thanks in advance
Hi there over here in the UK its difficult to get the acids because we had a number of idiots using acids to burn flesh . The UK government made it clear you have to be licensed to use hazardous chemicals and to have the right protective gear visited by health and safety yes that's why it's difficult to extract gold from electronic wastes.
To bad Im willing to but all the e waste you have
It'd be interesting if was subtitled in Spanish, French or Portugues, for I've problem to understand the English spoken in America; I've to see this video many times to try understand everything.
you seem pretty good to me. love from america :-)
Some HELPFUL TIPS for you Archimedes : 1 when you finish the hot water wash... rinse all your gold powder out of the beaker into a coffee filter with Borax already in it, and twist tight to ring out any excess water. 2 the powder does not need to be dried out completely . 3 wet sand your crucible bowl with 2000 grit sandpaper smooth...then fire it red hot and add Borax too hot glaze it hard. 4 Now once you have crucible bowl perfect add some more Borax and place the whole twisted coffee filter in and start the firing with propane 1st until it gets blood red hot, then go too acetylene brazing torch *( Not Cutting the cutting one )*because it will not blow the powder gold dust out of the crucible.
Thank you very much For your advice, I will take your way to use.
Robert Fields, i read your suggestion to archimides is perfect professional. May i know how do i seperate a fe2o3 hematite iron sand from tiny little palladium platinum in it. I use aqua ragia to leach it but iron are also leach into solution. The ore has been process by ballmill and concentrated by shaker table..

how to increase the weight of gold with zinc dust ??
Can we foound gold from zinc powder
robert give your insta id i want to talk with you brother
Gold salt is a powerful oxidant, zinc powder a good reductant. Zinc is zerovalent in its metallic powder form, meaning it has 0 charge (not a salt). When mixed with gold salt with a charge of +3 per gold atom, electrons from the zinc powder are transferred to the gold, this reduces the gold iii to gold 0, which is the metallic non-salt form of gold, zinc loses 2 electrons to become a zinc ii salt. In essence, zinc and gold switch places in terms of salt vs metallic form. The optimal molar ratio of zinc powder to soluble gold salt is 3:2
Woow you mean salt gold waste fusion plasm spherical..yes..tk so much ..yourscience thise video
Amazing this video
really cool explanation. Which country are you from sir?
With that said, I just subscribed to your channel! I have a question, can caustic soda be used to denox aqua Regia. I tried it. Im on day 5 of letting it settle 😳
@@BullProspecting Caustic soda: (Na+ OH-) is not able to be oxidized and thus there is no way to reduce the NOx in solution. If the solution is no longer acidic and at neutral pH, the oxidative species may have decayed by 5 days but no, caustic soda doesnt denox. If you are at neutral pH or even just slightly acid youl have more problems on your hands now. If you add Zinc it will drop the gold from solution slowely but the zinc wont dissolve thanks to no acid so you will have a mess. without a strong acid environment, SMBS won't react with to form SO2 gas which is needed to drop the gold. To neutralize NOx you need something redox active towards the NOx like urea, metabisulfite, or vitamin C. In short. Urea or vit C are to deactivate the solution but not drop gold. They just save you money on zinc and SMBS. Zinc and SMBS are to drop gold out of acid solution but in a large excess they can both deactivate the aqua requa solution AND drop out the gold. So: Au-Auqua Regia --> urea or vitc --->Zinc or SMBS ---> Gold powder. OR. Au-Aqua Regia ---> LOTS of zinc or SMBS----> Gold powder.
Good.
Thank you🎉
Your video is excellent. I have good content of pgm mix in iron ore. The ore obtained through gravity separation. How do i separate the base ore and take pgm out ?
Muito bom, técnica diferente 👏👏👏
Good job
Recovery of Gold by Precipitation with Zinc.
This sample has 10-20 grams of Zinc, which theoretically can precipitate 0.7 grams of gold from pregnant solution refining or aqua regia acid after use
Wanna talk with u can send me your contact details
thank u.
what u tp no
How much was IC cheap weight
How much gold does per gram of zinc can precipitate? Any table to refer sir?
سلام عليكم ورحمة الله وبركاته شكرا استاذ حفظك الله وزادك علما ونورا تحياتي لك وألف تحيت من المغرب الشقيق
Thank you for teaching me how to do this.
What is that Zinc Powder called there are many types of Zinc Powders can you specify which one it is
That has the look of a homemade melt dish...
I wonder would you mind sharing what you made it out of? Or better yet maybe even make a video on the step by step procedure and all inclusive list of ingredients
Great job! Your video was fantastic. Do you know anything about iridium ? I have ore containing 40% Ir 43% Cu and 7% Au and other 10% not as interesting. i would like to know how to separate them efficiently.

Awesome video! Thank you!!
OMG!... This was hard to watch, first you left gold dust in the glass beaker. Then you blow the gold away with your gas torch, your gold losses must be high. If you sweep the floor you might get an ounce or two of gold at the end of the year off the floor......

Hello brother .In our area .Water in gold but micro bit we can't see but it is scientific proof .How can I remove gold from water . Please reply
Hello Sir, thanks for the video. When I used aqua regia to dissolve 1 g gold metal 18 Karats (Ratio 3:1 AR), after precipitating with SMB I got only 0.2 g powder even HNO3 was neutralized, what's the problem?
vary informativ and inspirin video
Kindly help me tayyab
Grats for the gold you have, however, this is kinda pain to watch. How about to test, if there is gold in solution (SnCl2). May be boil the solution and let it stand for some time is more effective (less work). This zinc powder is effective, no doubt, but so much work and chemicals... FeSO4?
Good..👍
I like the video almost as much as gold
Thank you very much 🥰🥰🥰🥰
How many minutes do you wash the gold powder with hot nitric acid?
3 time
Thank you very much too...
Can you use the same method - Aqua Regia - if dust gold is located in dirt and then use sodium metibisulfite
Hey there! Thanks for watching the video!
Pls. can you tell us what are the other chemicals you use before the zinc powder and what is zinc powder? Pls.
Para ko zinc boltey h
Nhi
Ummm… so now if you use the zinc powder you have to use MORE nitric acid to separate the zinc from the gold powder instead of just using SMB which then would be your final step to get the gold mud into your coffee filter letting it dry and then melting the powder to make a gold bar.
Of course adding SMB AFTER you put in Urea so that it won't keep turning into liquid from due to the remaining nitric acid and hydrochloric acid continuously breaking it back down.
No what he is saying is smb cant remove 100% gold so after smb recovery he runs a second parsipatant to remove gold lost in solution with the zinc so instead of getting 95% or so hes squeezing out every bit by double extracting the same liquid
Sir how to recover gold from gold solution??

Hello, nitric acid and hydrochloric acid form acid. Does acid dissolve gold?
Yes, a mixture of nitric acid (HNO3) and hydrochloric acid (HCl) can dissolve gold. This mixture is called aqua regia (Latin for "royal water").
The chemical process works as follows:
1) Nitric acid oxidizes the gold to form gold ions (Au+3).
2) Hydrochloric acid provides chloride ions (Cl-) which react with the gold ions to form a soluble chloroauric acid complex (HAuCl4).
The overall reaction is:
Au (solid) + HNO3 (aq) + 4HCl (aq) → HAuCl4 (aq) + NO (g) + 2H2O (l)
This is one of the few ways to dissolve the relatively inert noble metal gold. Aqua regia is able to do so because of the combination of an oxidizing agent (nitric acid) and a complexing agent (hydrochloric acid providing chloride).
Individually, neither nitric acid nor hydrochloric acid can effectively dissolve gold on their own. The mixture of the two acids is required for gold dissolution to occur efficiently.
So in summary, yes the acid mixture formed from nitric acid and hydrochloric acid, known as aqua regia, is indeed able to dissolve and solubilize gold through a redox and complexation process.
U can use uriya and fairus powder for gold recover.. better then zinc powder.. Im always use u riya and fairus powder
Great job
I didn't understand the gold powder in the last step. It should be brown or black.
After washing with nitric acid What color should the gold powder be?
how about recovery Platinum ,Pd and Rhodium
If the zinc powder is so good as to get the final amount of gold why do you use the sodium meta bisulfite at all. Why not just use the zinc powder?
Good
Great full you happy happy thank
Hello sir. I am a beginer. I want your advise to reduce the fog generated by aqua regia during pouring into the solution which is very dangerous. I really worry for it (my friend already lung infected caused it). How to minimize it, such that it can not spill of the beaker? Or it can be over come by using a dust collector to suct each of fog arise? Thanks before 🙏
