- Gold refining is easy (and cheap). This video provides highly detailed and easy to follow instructions on the refining of jewelry, jeweler's scrap, electronic scrap, panned gold and pretty much all forms of gold.
The most advisable and detailed Video in UA-cam , thank you very much , after watching your video I got better knowledge about refining gold , wish you all the best and thanks again 🙏
Everything sreetips does is explained here
I truly wish I would have watched this video 1st! It would have saved me so much gold, time, headaches, panic attacks and money
bs
I wonder where the Aztecs, Mayans and Egyptians got their variety of acids from?
All that information is probably in the Vatican
bread video thank you very much
I tested the Hydrochloric acid I used to remove iron from ore and it tested Orange quite thick. Then I tried the Ammonium test one with it and it looks more white and thick. My reckoning is magnesium was in Ore. I thought the Gold would show up? I will take the Aqua Regia from the kit that I treated the ore with next and try to extract more gold from half of that to see if it will get more saturated rather than waste its ability. The Aqua Regia was 500ml and 50 grams over the specific gravity it should be normally. XRF on the ore Hematite was 90% iron and about 5% PM of many kinds at least half of them the rest copper, Nickle, and sometimes cobalt. Study study getting a clue. I would like to get the IPMI one recommended or Hoke book. If you have a good source I would be grateful. Thanks Oh one more thing the Bottom of the Aqua Regia has settled out a yellow powder? Would it be gold or what? I have not put in anything else yet just MX3
Great video thank you, will have a look at your products .
I’m mid way through your processes and as far as I can tell this is going to be my preferred way to recover and refine all my gold
If you put up affiliate links for the equipment we need, I bet you'd make some extra money, and we'd save time trying to find appropriate fume scrubbers 😅😂
Thank you so much for the video!! I'm watching and rewatching!

Hello again.
I've heard that mbs will also precipitate Pt or Pd so the end product will have Pt and Pd if they were within the solution.
Some people are using iron sulfate to drop the gold claiming that it does not precipitate Pt or Pd.
Will switching to quadratic precipitant prevent precipitating Pt or Pd with the gold?
Please advise, thanks!
Iron sulfate will drop gold and nothing but gold.
Is it better to put the gold mud in a beaker, add Hydrocloric Acid to it, and then slowly add the Nitric acid with a Pipet until all of the gold mud has disolved into the solution ! This way you will not have excess Nitric Acid that you will have to get rid of.
Yes, it is much better
Quardarpole precipitant means?
Thank you for the detailed instructions. I added NaSO3 to HCl and heat them up so the former can dissolve faster. But after the solution cooled off, the salt recrystallized and the solution returned to its original color (from the yellow color of aqua Regia).
Please advise on how to stop this reversing reaction.
Thank you.
Presume you mean sodium nitrate (NaNO3), not sodium sulfate. By heating the solution, you enable far more chemical to dissolve. When the solution cools, the some of the sodium nitrate can no longer remain dissolved. That would indicate that your ratios are incorrect (too much sodium nitrate per liter of solution). If your ratios are actually correct, it would mean that you are evaporating a lot of solution during the dissolving process (changing the ratios). Just keep your ratios correct and the problem will not reoccur.
@@shorinternational3841 Yes it is sodium nitrate not sodium sulfate, my mistake. Thank you for your explanation, the temperature I set was probably too high, which caused lots of evaporation. I will add more HCl to achieve the correct ratio. Thanks again.
My Aqua Regia came out dark green after I dissolved the gold scrap. I already filtered the solution 3x, it is now clear but still has this dark green color. Is this normal or is it contaminated with something?
Please advise, thanks!
@@tvu98 No worries, the color of the solution is a result of the dissolved copper content. It can be green, dark green, brown, even a brown so dark that it's almost black. The color is unimportant and has no effect upon your results.
@@shorinternational3841 Thanks. So when the gold is precipitated will it be mixed with copper?
And how about other Precious Metal like Pt or Pd how do we detect their presence? Thanks.
Good luck. Get more gold.
How to remove iron from a refined gold and what give a clear shine to gold bar
Presume your iron is only on the surface of your bar, a result of contamination from your cast iron ingot mold. You can remove it by heating your ingot with a torch, then lightly sprinkling it with ammonium chloride. The ammonium chloride will vaporize, taking the surface discoloration with it. Be careful not to sprinkle too much on the ingot- the ammonium chloride vaporizes and will make a lot of smoke if you spinkle too much.
However, the best way to both avoid iron contamination and also get an easy, smooth shine to the ingot is to use a graphite ingot mold, instead of steel or cast iron.
Some say that Corn Starch can be used as a Precipitant, Have you herd this ? What do you think ! Thank You for your prompt answer to my previous question !
Corn starch can be used as a flocculent. If your precipitant has resulting in very tiny particles (a common reaction when working with sodium metabisulfite), the particles tend to float and decanting or filtering becomes a challenge. The addition of corn starch will clump the particles so they settle more quickly.
@@shorinternational3841 Could a person simply add some JetDry to the Gold Mud in solution to reduce the surface tension of the solution causing the ultra fine gold particles to sink to the bottom of the container making it easier to decante
@@cbarkerify The easiest way to remove surface tension is to just spray with Static Guard. However, the only thing that surface tension does is keep some particles suspended on the surface of the solution. Fine particles not on the surface will still tend to float within the solution. This makes filtering or decanting very problematic. Flocullents can be used, but really, the best solution to this problem is to use a precipitant that results in particles that are large and heavy.
@@shorinternational3841 corn starch?! I've never heard that one! Sounds like a fun experiment.
At the step of adding urea, we get gold, but out of the remaining solution, how would we get copper if it was in the impure gold?
The urea removes free nitrogen ions but does not precipitate anything. For that, you need a selective precipitant, such as Quadratic Precipitant.
Copper is a common in karat gold (jewelry) and most other forms of non-pure gold. It cannot be selectively precipitated from solution. However, once the pure gold is precipitated out of solution (and the pure gold mud is separated from the solution by either decanting or filtering) all the other metals can be precipitated out of solution by the addition of either zinc powder or aluminum foil.
On person who refines his own gold on UA-cam uses Sulfuric acid to get rid of any Lead that might be in his gold mud, what do you think ?
Sulfuric acid will remove lead, but this step serves no purpose. The aqua regia process removes the lead and all other metals, as well as other contaminants, from the gold. Regardless of the lead content, typical purity from aqua regia is 99.95% (99.99% if refined twice).
I have been using muratic acid and chlorine bleach at ratio 2/3acid 1/3 bleach pour the solution into ore quartz sand stirring and let sit for min 4hrs or even days. I then pour off the solution until there is only the solution no solids noticeable. Then I mix mettasulphate and water to the solution let sit min 4hrs. The brown sugar looking solid then with double coffee filter paper then dry the paper and collect the dust that is on the paper.
What is it I'm missing as I still end up with impurities as buyers won't even look at it.
A step by step recipe would be greatly appreciated
For a variety of reasons, I would recommend you use different chemicals, such as the ones detailed in this video. However, that said, if your purity is presently suffering, it is not the fault of the chemicals you are using. The solution is either not free of particles at the time that you start precipitating (most likely cause) and/or you are not rinsing the refined gold mud thoroughly at the end of the process.
Sir ji 1kg Nokia phone me kitne gram gold nikta hai.
When gold stone crushed and heat it in nitric acid why it gives difrent colors? and how to know what kinds of metals are in solution?
The nitric acid will dissolve almost all base metals (but iron and steel don't dissolve well in nitric). It will also silver and palladium. All the more noble metals (gold, platinum, etc.) will remain undissolved. However, their physical shape may change if they were alloyed with metals that dissolved. Changing particle shape can affect the way light bounced off their surface, changing the color of the metal.
@@shorinternational3841 is gold nanopartical are gold? If yes then how i get gold from nanoparticals? What I do to get gold particals instead of nanoparticals by smb plz help me i am practicing for 3 months but did nothing, lots of thanks for helping me
@@sayedalisafishah6666 The very small particles that precipitate using smb are pure gold. The problem associated with them is recovery. Assuming that you don't have 1/2 micron filterpaper and a powerful vacuum pump nor a centrifuge, then decanting is the only reliable method of recovery. Because the particles tend to float and are sometimes so small that they are invisible, it is necessary to carefully decant the liquid. Repeat the decanting after waiting a day for any particles poured off by accident to settle. Repeat again the next day, and possibly an additional day. By this careful decanting, you can recover all your gold.
Alternatively, you can simply use a preferable precipitant.
@@shorinternational3841 sir I collect the nano particals at the top in solution (dark shiny brown color) and kept in 25ml bottle after an hour liquid change its color brown to very light blue and some shiny white sand in the bottom????did this process works below 10c temperature?
@@sayedalisafishah6666 If you have done an ammonia rinse, a blue color would be typical. However, the color of the solution is not important. The shiny white sand at the bottom may be undissolved chemicals. Precipitation will work at almost any temperature, but at lower temperatures precipitation will take longer and require more chemicals. The general rule is this- for every drop in temperature of 10C, the precipitation time will double exponentially.
Hi
I have a question is caluanie muelear oxide like nitric acid ?
This product is used for crushing and processing precious metals and semiprecious stones. It is used for processing precious and semiprecious stones, crushing metals in the chemical industry. In aqua regia, nitric acid acts as a catalyst, encouraging the chlorine in the HCl to bind with the metals, creating soluble metallic chlorides. This is not something that caluanie muelear oxide can do. So no, it is not like nitric acid.

How to get nitric acid
This is a highly corrosive liquid and is generally only available through a chemical supply house. We recommend you use one of the alternatives- sodium nitrate or MX-3 Concentrate.
@@shorinternational3841 thank you
@@shorinternational3841 Will MX-3 Concentrate dissolve silver?
All this extra crap in here is so confusing I just want instructions on how to use the kit that I bought that are straightforward
The problem is likely because you are watching the wrong video. That video covers the many chemical options that are available when refining with aqua regia, not just the chemicals that are included with the kit. The video for the starter kit is at this address: ua-cam.com/video/t0lTUmoSCMc/v-deo.html
