Gold Reduction with Oxalic Acid -Complete Process
Ғылым және технология
www.goldnscrap.com/index.php/g... ** In this video i'll show the complete process for the reduction of gold from chloroauric acid using oxalic acid and pH adjustment.
This process is used exclusively as a second refining step. Meaning, the initial Aqua Regia solution already contains high putiry gold that was refined once in to the area of 99-99.9%.
Unlike The previous video (see link below), the gold dropped this way doesn't precipitate as a cool lava lamp, but rather as fine brown powder that clumps together easily. Nice and shiny looking Dendrites might grow here and there. It is still very pure though :)

The whole process is a lot more than I knew a few minutes ago. I think it is very cool. The man knows what he's doing. So, stop complaining.

You are a legend ! in some other countries, you gotta be a servant for years to learn this, yet here you teach openly and freely. once our lives end, i know you will feel something extraordinary for what you are doing now with your videos. totally the opposite compared to the ones that knows, and keeps it all to themselves.... Thats the difference of being a giving person, or a selfish person. You win in the end.
This looks like a fun, profitable hobby, but seeing as how I can barely manage to make an omelette, I'm guessing this process might be a little above my skill set..

I might some day when I have a ventilated, safe environment to do it in.
Seeing gold come out of dirty materials, it's like I'm watching alchemy. Excellent videos!
The narration was not made by me. I'm struggling with my english as it is... :) Would love to know what you guys think about it. This is the first time and i'm sure it will get better in time...
Great tutorial and very informative. Take so much trouble to make some gold, if you don't get a very good recycle supplies, its not worth that time to refine some gold. But really this is good education!
To all those randomly spouting information here. 1. No these chemicals aren't expensive, but they can be tricky to obtain in high concentrations. 2. Yes if you could get old PC parts by hauling them for someone cheap/free you could turn a profit. Gold is very heavy and worth minimum of $1100USD an ounce. You need time, money and expertise to pull this off but you could do this as a hobby and make a small amount of money on the side doing this, however without industrial sized machines and a large amount of scrap computer parts you're not going to make a living.
Good to see an expert sharing knowledge with the public.
It is produced by dissolving gold in aqua regia (a mixture of concentrated nitric and hydrochloric acids) followed by careful evaporation of the solution Au + HNO3 + 4 HCl → HAuCl4 + NO + 2 H2O Under some conditions, oxygen can be used as the oxidant. For higher efficiency, these processes are conducted in autoclaves, which allows greater control of temperature and pressure. Alternatively, a solution of HAuCl4 can be produced by electrolysis of gold metal in hydrochloric acid: 2 Au + 8 HCl → 2 HAuCl4 + 3 H2
I work at a Gold and Silver Refinery, our process is similar except we electroplate our auric solution onto titanium cathodes with 99.95% gold anodes as feed stock, and only use a sodium compound to precipitate our waste auric solution in large tanks.
How about the other way around - base first then oxalic acid? Any pros and cons?
I agree with you - most people seem to have difficulties filming and doing their thing at the same time.. while talking. As a matter of fact, it does become confusing for the narrator at some point, but that's not an excuse. Especially when it is added as a separate recording (or at least it seems so). Good luck in your endeavors BTW. It's rewarding to see a person who accepts other's opinion even if it confronts their own.
Can all these acids be found over the counter? Where does one go about finding them.I have a few old Hp cpu boards and hdd controller boards from the sixties that are loaded with gold.
why go thru adding Ar + HNO3 only to have remove trace elements at the end? why not just HCl/HNO3
so is there a way to also make use of the dissolved copper and nickle from the first stage of processing? it would be a waste to dump those solutions
Great video! i really like the clear step by step explanations.
aside from the fingers are there any electronic parts like in tv or radio or old cellphones where you can get gold?
I have a 12 ounce nugget that is approximately equal parts of copper and gold. Can this method be used to separate out the gold?
Because this is not a phase seperation process. Oxalic acid reacts with NaOH and for Oxalate and Hydrogenoxalate anions. Organic solvants such as BDG may react differently to alkalis.
So where can you buy all the chemicals and stuff that you need? And how much does it cost and how much do you get? I'd like to try this but i don't know where to find the chemicals, and how many times can you reuse them?
I appreciate your voice over I'm a dislexic and was about to slow down the video to a speed I'm able to read at you have no idea ! Thanks
there are also several different ways of reduction. But your method is fast & cheap. thnks for video
Hi, thanks. What you are doing is good enough. The process with oxalic is a re-refining process to ensure four nines gold or better. That is not always needed. For example, a jeweler that cast alloys would be satisfied with 999 gold
So, what's the ratio of return? How much gold can you recover and how much did you spend on the materials to recover it (not including the equipment)?
Amazing!! And such pretty gold!! Can you show us how to refine palladium , platinum , rhodium and iridium ???
can i use the dirt to make a mold for hot melted aluminum to make a mold for the liquid gold to form what ever shape i want instead of dripping it in water
So how much gold did you end up getting from all those scraps in ounces?
I have 2 questions, 1) flaming gold power with some carbon-butane-like torch will not add some wastes from combustion? and 2) how many gold did you recover and/or did you recover the money expend within this long proccess?
Very good video, requires lot of patience and very good knowledge of using chemicals.
Do you know how much gold you get per electronic item (sorry, very ambiguous but a few examples would be good)? Do you need to melt down like 20 motherboards to get a gram of gold or something?
If you are from the US, You should be able to find small quantities online or at local chemicals vendors.
It looks great, how much scrap you need for that much gold, and what do you use?
Hello benim aque regia sizinkiyle aynı düşen tortularda aynı kahverengi onları küçük tüp pürmüzle erittim hiç bişey çıkmadı neden her tortu altın değilmi yoksa. Başarılar
Excellent knowledge and process demonstration keep it up boss - can you specifically explain on when it is supposed to be hot and when cold thank you
Is it possible to just melt the gold foil flakes into nuggets or a bar instead of going through the entire refining process? I understand the gold wouldn't be 99.9%, but would still be between 9 and 14k right?
I can't understand it. the videos jump from gold fingers to scrap jewelery and they start in the middle of the video. I can't follow the steps because each video is different I wanted to see how you get gold from just the gold fingers I'm a little confused.
What about the nitric acid, should it be neutralised before the precitation?
Yes Heisenberg, i love your videos.
What is the reason for washing out with HCl and NH3 after precipitation?
are there places where I can bring in my gold fingers so it can be processed?
yes it would lovely to here some numbers. How many fingers to yield a gram of gold.
Is the amount of gold you actually get worth all of the time and material you have to put into it by the time you pay for your chemicals, electricity and gas for melting?
What amount of scrap is needed to obtain the amount of gold shown here?
hello, how much did you invest in all the chemicals used in your videos and how much gold did you get in return?
well if it takes 160 plates of gold to make $60 can u tell me what did u make?? any ways my dad n his dad made like $7890.00 with 4 buckets full...........
Very nice vids. Thanks for showing us in a clear way how to do it and thanks for all the cautions too, which is wise.
can you tell me is that the remains of circuit integrate video? if so what part of three (magnetic part, slica, ash) you used in tis process?
Hey that was pretty cool. is this the gold from the fingers? what is the weight in total? and can you please list the tools needed to achieve the final result? thanks!
could you refine gold by melting the gold then skimming all the impurities off, to at least get 14k gold to 18k gold?
hello i was woundering , what if there is copper and other metals on the pc borads, will it melt the copper and that too same as the gold and then the gold ruined. this is what im confussed about. which no1 explain's. or dos it just melt the gold and non other metals thanks
No. For the reasons you mentioned. No need to destroy a perfectly reusable BDG. You can either adjust the pH of the Oxalic acid solution to 5-6 beforehand or just use Bisulfite solution to reduce the trace left over gold in the organic phase. But all this has little to to with the process described in the video. Apples and Oranges.
Hi... Look at the equation in the video. The oxalic acid does not remain as it is, so there's nothing for you to recover. You could buy rather cheaply, sodium or potassium oxalate and make a solution of the salt and use that instead.
Im curious as to what the weight of the final product is...?
this is great and all but i doubt that making gold out of pc parts is profitable. i mean the time and effort required to find and harvest parts then on top of that all the equipment to reduce it all down to pure gold does it really bring in a worthwhile profit?
nice bro, but is it worth it all the energy and materials + recyc of the waste?
The materials your putting into the solution, what types of things are they and what should not be in that solution, plastic, aluminum ect. thanks
hi, i took some cpu pins added muriatic acid and peroxide, after a few days i got a black liquid but see no gold, i took out the liquid added more peroxide and it turned into yellow i then added sodium metabisulphite got a little reaction but then nothing after that, what may i be doing wrong ?
So how many grams or ounces did you end up with ? Awesome vids btw, thank you, I'm definitely going to try.
Can you tell me how to recover the oxalic acid? I have a book on refining and the solvent extraction method is shown in this book clearly, but oxalic acid is expensive so recovering it would be helpful. I paid a lot for mine and I would like to find a cheaper source.
So the sodium hydroxide changes the ph of the AR to allow you to precipitate the gold..? Would it ALSo work to recover platinum?
i just cant sstop believing how we can utilize the available but scarce materials. Good job
I want to buy this complete system where I can plz help me out
How many Pentium 3 processors should I use to make 1 gram pure gold ? And if I have the pins seperated , should I use only HCl to seperate the gold foils ?
Remember, you start with acids (HCl + Acid Gold Chloride + some Nitric acid + Oxalic acid = pH0). That's why the addition of NaOH is controlled. I never want to go over pH1.
hello my friend congratulations on the videos, is oxalic acid a reducer to precipitate? and to neutralize it can be sulfamic acid? before precipitating with oxalic acid can i neutralize with sulfamic acid? Thanks
How much gold do you get if you have 1 kilogram of choloroauric acid powder
About 30 grams from that it looks like to me spot is $1100- so depending on who you sell to is what you get for it I'd imagine?
ive been wondering does the whole process worth the time and the cost?
can we used this method to recover gold from ram ic chips???
I´ve seen on another vid to voporide the chloroauric acid and then add the oxalic acid with out any adding sodim hydroxide.Do it work too ?
Out of curiosity, compared to the gold you obtain at the end, what is the cost of the chemicals and the total time needed to get from the Chloral Auric acid to the gold nuggest?
So kids when you tip your computors and mobile phones out, then get recycled in countries like India, where the labour cost and health standards are a lot lower, with the exception of the US dollar being a lot less in actual value.....What this gentleman is showing you is a clever way of getting gold back, I'm impressed. Thanks for the video's.
Dude, of all the cool shit I have seen on youtube, this took the cake. I bookmarked your website and hope to utilize this process on all of the scrap electronics I held onto. You're awesome man, keep up the good work!
Can you tell me how much oxalic to how much HAuCl4 at the beginning, the ratio. and as you adjust the mixture how much sodium hydroxide are you adding, say over an hour? Thanks.
Hi, what is the overhead to purchase and set up everything you need to get started with this? thanks!
Are the acids used available for public use?
Hello sir, what is the specific gravity, the yield of the gold
I wanna try this but it seems like a lot of work + I don't have the materials and chemicals... probably in the future idk.
Can you also include other gold items like broken 10, 14, 18K gold jewerly (or gold plated) at the beggining of the process to get the pure gold out of it?
Mr. Wizard never taught me this. Seems like a lot of work for not much gold. How much is that worth?
after a lot of research im instrested but where can i find a buyer i thought about the we buy gold but i was told there is none on the east cost from a connected but unreliable source cause he a hussler. So about how much was that in weight and value where can i find a buyer

I have gold or I crush it into powder and mix 22kt gold testing acid with it will this destroy everything that's not gold? And will the stuff left over be just pure gold? Please respond?
could you comment on the washing of the gold powder further and also the reducing flame your using, is it oxyacetaline, natural gas or map? do you think this is easier than dropping the gold out with "copperas", washing then using a electric furnace . Or the "SHOR" PROCESS?
Hi Fortunately, this concern is invalid. In the presence of a reducer (Oxalic/Oxalate), by the time you reach pH1, all of the gold had been reduced already. However, you would precipitate hydoxides of other non precious elemens (if present) by adding too much NaOH. But it will be dissolved away with the following water and acid washes.
aku punya mesin hp 2kl mesin cpu campur prosesor klu d proses menghasilkan berapa gram,termakasih atas jawaban nya
how many grams of gold was that?
Why did you "cornflake" the gold (Pour it into the water) rsther than cast it into a button to ingot?
What's the approximate value of the gold chunks you made at the end of the video?
How much is this worth? I know it has to be less than the computer, but this is at least like 30 dollars right?
how much this would go on price?
How much was it worth, and how many computers did you have to go through to get that much?
cara muito bom video mais eu queria que voce metirace uma duvida sobre çido oxalico aonde vende meu amigo
Pretty awesome. What is the weight of gold you recovered?
Hey there indeeditdoes, I just wanted to thank you for making your videos. There are more of them out there like yours, im sure, but yours are the first ones I have come across and feel that I do not need to look any further. I am no chemist, I am no hobbyist neither, I simply don't mind working for my earnings. And let me tell you, you make it look very easy. But I am quite sure it is not that easy. I do stumble on things late I have to admit. Your videos were posted 2 years ago. I have a question regarding what components to use for melt down. Are the pieces shown on your first video the only pieces to use in order to obtain gold? Please respond.
what is the rate of amount of that fluid to gold that you get from it? how much profit, if any, is made?
you can usually find oxalic acid at the hardware store near the paint section, I used it to clean driveway once.
...which is the percentage strength of the oxalic acid ? Thanks
can somebody give me a list of all the chemicals that i need to do this from a processor thanks
