United Nuclear lists a process for a carbonate leach leaving with a solution of uranyl tricarbonate. They mention the use of kerosene for precipitation but would your method of precipitation work as well?
Good question, the method in my video only works if insoluble uranyl peroxide can be formed. From this paper (www.sciencedirect.com/science/article/pii/S1876610213012800), it seems that uranyl tricarbonate (the leach solution in the United Nuclear method) forms a soluble complex with peroxide, and hence would not be suitable for precipitation. Feel free to try it out though and if you do let me know the results.
The reason the uranium nitrate isn't heated directly is because autunite contains impurities that also form soluble salts upon reaction with nitric acid. The precipitation with H2O2 is selective for uranium and thus is a easy way to separate it from the other unwanted elements.
In theory HCl would work as long as the H2O2 can oxidize the uranium from +3 to +6, although I am not sure if that is possible in practice. If you give it a go please let me know the results. If you have a source of neutrons (say from Pu-239) then you can use it in a breeder reactor with the UO3 to produce more Pu-239. Where you would get Pu-239 and if this is something you can attempt at home is another story.
@@unpairedelectron2886 thxxxx, then...Uo3 will be turned into PuO3 directly? I search PuO3, but there is not much information about it, it makes me doubt that if it exist.. ..... About the neutron source, I am going to get some helium ionized by electric arc( around 60kV) then become alpha and hit beryllium and emit neutron...I am not sure if helium can be ionized in this easy way.. For extraction of uranium using hcl..I may give it a try later. It seems that UO2Cl2 will be made.
@@endothermicexothermic4051 I've seen this method, uranium ore in hexavalent state is dissolved in HCl after crushing, alternatively you can add some H2O2 or even bleach(produces chlorine, beware) among other oxidizing agents to change teravalent U to hexavalent state in solution. Iron may be used as a catalyst for the reaction. After fully dissolving you can let the solution settle or preferably vacuum filter it. To filtered solution you add NH4OH to produce (NH4)2U207 which precipitates while also percipitating several other metals, optimally a pH of 5-7 would be slightly selective for the Uranium but in order to precipitate all of it a pH of 10 is achieved also percipitating other metals. Now you leach using Na2CO3 and maintain a pH of around 10 using sodium bicarbonate. This produces UO2(CO3)3-4 while leaving most other metals as a precipitate save for Molybdenum and Vanadium. Following this the Leachate is vacuum filtered and seperated into a smaller and larger portion with the larger one having HCl added to neutralize the leachate to pH=3 and H2O2 is added while solution is boiling(hazardous take precautions) and a yellow UO4•nH2O precipitate forms. Due to pH decreasing in this reaction, the smaller bit of leachate is used to maintain a pH of 3-4, the excess is kept for a next batch. Following this you can dry the UO4 hydrate and crush it to a powder and then cook it at around 300°C to form UO3 which is useful for further Uranium chemistry. I will try to find where I found this method because I do not have all the minute details.
I don't live in the United States so I get it from a local online eBay-like store. I do however see uranium mineral listings on eBay all the time, so perhaps you can check there.
This should work for all secondary uranium minerals or even some very rich >50% primary uranium ores. The main downsides to doing this method is you would need to waste a lot of nitric acid for low concentration ores.
I tried it out, put some barium carbonate into the ore then dissolve the ore in nitric acid like in the video. After that add sulfuric acid, this will precipitate out the radium/barium sulfate. (you need a bit of barium because there is too little radium to have a precipitate you can then get out of the solution)
You really just have to add some over time and watch until no more precipitates. This is because at the high temperature it decomposes pretty fast (you can see bubbling as it is added).
Hey, interesting video, i made a somewhat similar video recently, with less access to proper equipment and restricted chemicals, although i have found that Na2U2O7 precipitation tends to give a purer product than The peroxide precipitate. I think this may be due to vanadium impurities, but i am unsure.
Hey Rogers Nuclear, I just watched your video on extracting yellow-cake from autunite. It's a cool coincidence that we came up with such similar videos in a short period of time; when I first began work on this project there was no other video on TH-cam on this particular extraction. Uranium chemistry is so interesting, I do hope more people get into it. I'm curious to know how you figured out the purity of your product, since I would like to do the same with mine. Heating to decompose it to UO3 perhaps?
@@unpairedelectron2886I made yellowcake a variety of ways, but I took a sample of each, decomposed it, observed it's colour as the first indication of purity, then dissolving them in acetic acid, checking for effervescence or undissolved material, another indicator of purity, however depending on the type of yellowcake, the decomposition results in sodium carbonate as a byproduct. Then I neutralise the acetic acid, there will typically be a precipitate of impurites, I then filter it, dry the solid impurities, then weigh them. The Uranyl acetate solution can be evaporated and the uranium to decompose again, you can recover the UO3 by washing your decomposed mixture with water, as the carbonates and remaining acetates will dissolve.
That is insanely simple. How radioactive, Or rather, how much radiation is emitted by the new uranium yellowcake? And how does that compare to the unprocessed autunite?
If really anything else is left behind it should be less radioaktive. Because a lot of the radiation is coming from decay products like radium I think.
Thank you for your video.how can we sell this uranium yellowcake concentrate?about 3 years ago i succeeded in extracting yellow cake from my gold ore here in indonesia.this was the outcome as a byproduct after oxidative pre treatment using H2SO4 and HNO3 to maximize gold ore recovery.
I love how I'm researching this to make an atomic bomb for my Mad Artificer in DnD. "Listen guys, if the bard can't seduce the dragon we have plan B. Worst case scenario we die and cause an atomic winter across the continent, best case scenario we die and recreate the sun." Suicidal Barbarian: "I don't understand but yes." DM: "Wait how the heck did this happen?" "Remember those rocks I collected since session one and treated them with nitric acid and peroxide?" DM: "Ah fuck"
@arizonaexplorations4013 funny enough a year later I see The Click's video on it. That artificer had a different more DnD approach, mine started with making larger and larger bombs eventually escalating to brewing Napalm and Enriching Uranium, segragating isotopes and making a bowling ball out of it.

It's a pretty messy setup. As the video progresses, I could see spots forming on the fumehood surface. That's just unnecessary contamination. It could've been done way more secure.
What’s TH-cam doing right now? I’ve never in my life searched this and I’m getting like a dozen uranium refining….oh shit…. I really hope a bunch of terrorists aren’t searching how to make nukes to the point it’s made it into the algorithm. This is actually really concerning

I did not in any shape or form imply in the video I was enriching uranium. From Wikipedia: Description Yellowcake (also called urania) is a type of uranium concentrate powder obtained from leach solutions, in an intermediate step in the processing of uranium ores. It is a step in the processing of uranium *after it has been mined but before fuel fabrication or uranium enrichment*.

So what you do than you smelt the yellow cake to get the metal uranium?
Is this "yellow cake" tasty?
Is yellow cake less radioactive than Autunite? I think it might be less radioactive as you may have separated out Radium and Polonium.
Exactly right!
@@unpairedelectron2886 do you have any plans on turning the yellowcake into UF6
All a nice Yellow Cake like that needs now is a dreamy Chocolate Frosting! 🤗
How selective would this be for the uranium? Will the precipitate be "pure"
Welcome to the fbi watch list everyone!
Are you using a magnetic stirring rod as well?
Yes, the white bar in the beaker is a teflon coated magnet called a "stir bar". There is a spinning magnet in the hotplate that causes it to rotate.
@@unpairedelectron2886 Oh thank you. One other thing where exactly do you get that particular Autunite?
i didnt have to boil the uranyl nitrate in the end : the precipitate appeared after I started to neutralyse the acid but in a very fine powder form.
Hi. Can this process be done with uo2 (pitchblende) ore? Thanks in advance
Yes, but you need to make sure it has a high uranium concentration.
@@unpairedelectron2886 Do you know any easy ways to check uranium concentration? sorry if this is a dumb question I'm new to this kind of stuff.
Anyone know how this powder could be turned into a solid block?
Does yellowcake generate electricity in solar cell?
Thanks a tone for this, actually, using this video, I was able to complete my personal project with this.
How do you get the chemical answer by combining 2 elements? I never took chemistry so I'm new.
Can such ink be made that can be seen only when wearing special goggles?
Do you have to use uranium crystals.
Can't you like use normal pitchblende or uranium ore?
Pitchblende is expensive and uranium ore has very little uranium
What is the make and model of the hot plate in the video?
It is a Thermo Scientific Cimarec SP131325 Hotplate Stirrer
Can Uranium nitrate be heated directly(400°C) and obtain UO3？why H2O2 is used
The reason the uranium nitrate isn't heated directly is because autunite contains impurities that also form soluble salts upon reaction with nitric acid. The precipitation with H2O2 is selective for uranium and thus is a easy way to separate it from the other unwanted elements.
1. Can I use HCl replace the HNO3？
2. Can UO3 undergo nuclear reaction? E.g: UO3 (where U is U 238) +neutrons, and make Pu239
In theory HCl would work as long as the H2O2 can oxidize the uranium from +3 to +6, although I am not sure if that is possible in practice. If you give it a go please let me know the results.

Yes, you will just have more water to boil off.
now how do we turn this in to the metal
