One of your best videos yet. "I'll eat my hat." So funny.

Just fantastic. New CPO update; have been contacted by one selectee, other than that, have not seen or heard from any of them. Signed no charge books, visited by none of them. Times have certainly changed. Keep up the excellent work.

Great to see you back. Praying you get the rest you rightly deserve. Lmao... no more Sreetips withdrawals. Looking forward to more awesome videos. Greetings from Phelan California.

i am reading an old refining book on pdf and fascinated how smb hasnt got a mention and the copperas being used like the stannous test for checking whats left in solution by dropping green crystals in and look for brown forming on the crystals. it mentioned the stuff spoils and becomes useless when it loses the bright green colour on the crystals, perhaps thats why you needed so much? also interesting the mud dropped by copperas may be more dense compared to smb mud judging by the surprise from yourself by how much it melted to.... and also amazing how much it needed to be rinsed, great video.

Would copperas be a good first refine and then follow up with SMB for increasing the purity? Would the iron still follow the gold with the SMB if it wasn't fully rinsed off?

wouldnt it be faster to use multiple filters/funnels to speed up the copperus going into ur gold solution?

Hello sreetips. Nice video. I dont mind that one broken shot... happens. With the amount of gold looking to be so small, it might be the different way of precipitation. With the SMB it is rather quick, and the gold forms quite a lot of smaller flakes, allmore or less the same size and they do not compact that well. Those are also more easy to rinse, as they have a lot of space between them. With the Copperas it seems to have more time to form bigger gold crystals at the beginning, and later, when the solution is less dense, it forms smaller flakes. And those flakes and crystals just form a more compact "gold sludge", which is apparently more difficult to rinse. The gaps between the granuals are simply smaller. Of course you get a more clean precipitation, but that amount of rinse-waste was a lot. More or less comparable to the difference with silver, one cementing on copper the other with lye and sugar.

That was awesome well done

Amazing as always!

Great video, very informative.

slow addition of reducing agents will create a more dense and cohese precipitate. Faster addition will create a porous (less dense) precipitate. Moreover, the iron salt is already dissolved in water prior to precipitation, while ammonium metabisulfate yu add it to the solution. This induces nucleationa nd cristallization on the shell of the dissolving ammonium salt granule, thus creating a porous less dense gold precipitate. Plus iron sulfate may induce a different precipitaion and cristallization mechanism, rather than ammonium met4ebisulfate, but for this last one im not sure.

I believe I have watched all your gold melts and that is likely the purest bar you have cast

Hi sir if I have copper plated gold and rhodium can I separate

I love your videos they're very informative thank you for everything that you do. Having seen so many of them, I'm aware that there have been different practices employed by you over time.. such as adding dry sodium metabisulfite, aqueous smb, diluted undiluted solutions AR AP, ice bath and none. Which leads me to my question. In this video you added ice directly to the solution. So. I'm wondering if you're doing this because you're trying to prevent glass breakage, and resultant losses due to the cooling coefficient of glass? Or is it a temperature sensitive reaction? Or are you trying to avoid a runaway reaction? Or is an approach to satisfy dilution as well as insurance against everything above? Or am I missing something thank you again

@sreetips

I’m constantly refining my refining techniques. I add ice before filtering because the filter works better, and slower, with a cold solution. During precipitation, with SMB, I always add ice when precipitating Two Troy ounces or more of gold. Precipitating with SMB creates lots of heat if there’s a large amount of gold.

I have found that the purity when precipitating with Iron (II) Sulphate is far superior to sodium metabisulfite, but is a bigger pain in the rear end... but almost hit .9999 on XRF testing :) I don't use copperas however, just buying Iron (II) Sulphate from Amazon, very clean and doesn't require filtration.

@sreetips

8 ай бұрын

I can eliminate rinses by dropping the gold with SO2 gas. Adding SMB puts chemicals in the gold. There’s no chemicals with the gas. Just clean precipitation.

I think what happened with how it didn't "look" like it was the right weight comes down to density. I'd be willing to bet that the change from MBS to Ferrous Sulfate, and maybe the slow drips down the side of the beaker, made the physical size of the gold change that allowed it to pack down into the sponge. I think that is what that is called, at any rate. Not a refiner (or even a chemist) just like watching the videos. I agree that the MBS reaction is much more 'fun' to look at. And handy with the white foam letting you know you are close/done.

Could you not precipate the platinum group metals first

When you use iron sulfate...you dont need to deNox sulution by sulfamic acid?

Denox = remove excess nitric. You don’t need to remove excess nitric because there is none to remove.

I'm curious about all you were doing with the ferrous sulfate (and in my experience, it is top notch for greening up fruit trees, setting back moss, harming slugs(big +), and as a cheap way to add iron to my aquaponics system... Anyway, when you added HCl to the solution, didn't you simply produce iron chloride and sulphuric acid? I would suspect that this is doing two things. One would be the same as the SMB and dropping other PGMs, but at a lower rate, because you're introducing iron, which is just an expedient version of your "waste bucket" displacement. So, you've got the illusion of some kind of better option, but the HAuCl already has HCl, so why did you pre-convert only some of your FeSO4, leaving a solution of HFeCL and H2SO4 (assumed)? Also, if iron doesn't drop other PGMs, then what is keeping you from sewering them after the "Waste bucket with iron, cementation" stage? I'd like to know a lot more about these angles, as I've not seen the FeSO4 used like this, and I already have a good and cheap supply of it for my fruit trees, aquaponics, and my war against strawberry-stealing slugs.

@sreetips

Ferrous sulfate is recommended by Mrs Hoke in her book. She also instructs to add HCl to get it greened up before adding to the gold. I’m not sure of the chemistry. I’m just doing it the way I learned it from professional refiners. Sewering the waste before it’s been treated. That’s like pouring acid down there. I prefer removing the metals on iron first, then dropping the iron with sodium hydroxide. That’s the way I learned it from the pros who taught me. I’m not a chemist. Just an advanced beginner and a hobbyist.

@@sreetips Ok. That explains a lot... I too am learning the ropes in this fun hobby. By the way, I did watch your video where you neutralize the acid with hydroxide after the iron stage. My point there about "sewering after that stage" was more of a question about "if the iron in chlorinated ferrus sulfate does not drop other platinum-group metals, then how does your cementation system assure you that they are recovered before you eventually lose them?" There is an excellent chemistry channel called NurdRage, who is a chemist with a PhD, and is starting to make videos with refiners in mind. He has some absolutely swell "no waste" versions of some stages that you already do that I guarantee (or no money back) will make you very happy. I recently bought some nitric acid, and the price made my heart ache for the amount of it that you lose forever. He's got some videos that show you how to recover it very efficiently, as long as you're willing to run another electrolysis cell.
