Yay ! Sreetips Teaching again ! Lov'in your videos best when you Pass the Knowledge on. Tin (II) Chloride can be made using Tin metal + Hydrochloric acid, but it takes a Long time, like a month, depending on temperature.

I pay attention to the volume of raw (source) material he is processing and final yield. The major problem is exactly the expectation vs actual yield. My brain was contaminated very early with the gold fever. It takes a very large volume of eWaste for example to yield a gram of gold. In the generic example Mr. Sreetips mention in the video, using myself as reality, I learned the hard way that it is not that SMB does not drop. At the end, I have micrograms of gold, it is like you can count the grains individually. It is easier to not even see whatever dropped. The I changed my mindset to micro-refining. Literally using those mini 50 or 100mL beakers is more than enough. I reduce the source (whatever it is, early Jan I had like 10 depopulated motherboards, I completely incinerated them and the result was a handful of grains). I do not have access to large quantity of eWaste. Maximum I manage to have like 20 SMB microprocessors. While recovering, you can see "a lot" of gold wire mesh, A LOT. However it is less than a gram.
ive done that with an instant conversion to black on the test. still no drop with SMB but was able to drop with copper, i used micro dosing with nitric so i shouldn't of had exes nitric, however im going to get urea to redo the process and see if it does better. love the vids. keep them coming
Hello Mr Master Sreetips. With all due respect I say that. I was wondering have you made or can you make a video that can get someone who wants to follow your footsteps what to do and how to get starter kit on inventory and everything needed to do what you do? Sure would appreciate it take care
Thank you for this! I found out the hard way that zinc oxide is no good for gold recovery. I cut the top off a tin can. So far so good! P.S. how long will it last?
There are many different recipes. Many ask for concentrated HCl. I just use solder (99.3% tin with 0.7% copper) and snip bits off into conc HCl to dissolve. I make sure that there are bits of free metal left. Works fine for many months. I regularly test with about 100mg/l gold solution.
Will that work just recipe that you explain work on silver and will it work on the other three metals that sreettips tested. Thanks if anyone can answer this
Great video thanks. Do you know what the effect of other metal contaminants in the Au solution will have on the test results? My gold solution likely contains Fe and/ or Cu.. and perhaps Au?? Cheers
Have you possibly thought of a follow up video to show others what a stannous test would look like with other metal contaminates still in the solution? Maybe also if there is more than 1 PM in the solution? I know the old saying of stannous test every step, but it seems that that can be confusing for some on the test outcome.
Awesome! Curious why the extra tin though? Does it keep longer or maybe just make it a more potent solution? Thank you. Love your videos. (Underground Editor)
Great content as always. But for the reasonably well practiced refiner who processes only karat gold, Is stannous chloride really necessary? The white foam thing seems to work well giving expected yields and if all waste solutions are reprocessed anyway, I personally don't feel compelled to add another process to my set up. My lack of vacuum filtration however... now THATS a pain in the ass!
@@sreetips I am curious of course yes. But i see them more as a potential bonus from waste processing. I'm new to this and have barely 1.5 litres in my stockpot and just a dozen or so used filters!
Love you videos, and, I have a question. I have the same issue you mentioned, the gold dissolved, making a beautiful yellow solution, but when I test it, there is no gold. My question, where did the gold go?
@@sreetips I started out with 10 grams of foils, from memory sticks, I guess they must have been much thinner than I had at first assumed. I'll give it another try, and thank you so much for responding.
I’m in the UK and the company I’m looking at for buying it list it as Tin (II) Chloride dihydrate ACS (Stannous Chloride) is this the crystals you refer to?
It seems to me, and I could be wrong…that when trying to get the gold from escrap that wether you’re doing fingers, pins, chips…there comes a time when you have gold or yellow liquid and you are ready to precipitate. My question is: if you are dealing with small amounts could you combine all the yellow liquids collected from various items so that when you precipitate it is actually an amount worth doing?
@@sreetips Thank you, also I have heard mention of a book on refining that seems to be the top book for me to read. Any Ideas on what book I possibly heard? There are plenty on Amazon but prefer to have the holy grail, so to speak, if there is one. And thank you for your time. I know it is precious.
@@sreetips Really my test was wrong .. very little genius palladium in solution. that's why I can't reach the color you see in your examples .. I made a new palladium solution in aqua regia and it worked ... thank you very much for answering! regards
I've run into this , but I'm wornering where the gold went if it;s not in solution. It's like it disappeared into thin air. Can you tell me where it went and or how I can get it back if possible?
Mr Sreetips, I am using your recipe for the first time. Mine does not get milkish. I am using distilled water plus HCl, Tin shots, and Stannous grains all from The Science Company. I made it to compare to the other 2 recipes I have. Shouldn't your recipe just get milky? Any recommendation on my case? Thank you.
It will be relatively clear for a day or two then it will turn for you. I’ve used my stannous solution well past three months by adding a few drop of HCl to reinvigorate it.
@@sreetips that's me! Lol I'm still trying to figure it out. I just made stannaus and tested and confirmed it. Nothing in solution. Definitely a live and learn scenario. I ordered tin shot and it took a while to get here so I was impatient and rushed it. Pretty sure I lost it all. 🙃 but it was a awesome learning experience! It truly was.
I followed this recipe and nothing happened. The stannous chloride dissolved but the shot did not. The solution is clear after sitting over night. I ordered the tin shot from Amazon. Any suggestions? Thanks!!!
I must have messed something up. I thought I followed your directions exactly. My gold test solution is 5 grains of 24k (Pampa bullion) dissolved in 100 ml AR then diluted with 100 ml distilled water. When I use the stanus chloride on filter paper with the gold solution I get no change in color. Any thoughts? I am very new.
Rex, I don’t know what you’re trying to do. I can answer simple questions. There are too many variables to consider. I don’t offer training or tutoring.
@@sreetips I would to make a gold solution similar to what you have in your Wheaton drip bottle. Did you use aqua regia and then dilute with distilled? Thank you sir.
@@sreetips ah, well then I'll stop worrying lol. I just saw the solution you poured out and didn't see any. I suppose with the brown bottle I couldn't tell. I'll get to test my stanous cloride soon. About to finish the nitric boils on 350g gold filled. Thanks for all the info! Said 700g at first. Forgot half the weight was the clips that I removed.
I made the solution per the recipe, but I’ve also noticed that it’s remained clear and the tin balls are not dissolving. Is this normal that I do something wrong?
@@sreetips i took 9.5gr of gold leached it in AR . All disolved nice. The i tested liquid with the fresh made stanuos solution /was made the same way as per y video/ and no results no color change when i put a drop if it on filter paoer with rich solution what i did wrong???
Just dissolved my gold, used the stannous chloride solution and nothing!? Is my aqua solution still reacting? Maybe I got a bad product to test with? I haven’t removed any liquid at all so this seems impossible
@@sreetips Figured it out. After doing some research, that 3:1 ratio of Hydrochloric Acid to Nitric Acid isnt exactly the best advice. I over saturated the solution with Nitric Acid. Went ahead and boiled it down to about 150ml, added more HA to consume the nitric acid and filtered it all. Adding the SMB seemed to take way better this time but its a waiting game to see if it precipitates. Let me know if any of my process is wrong. All was easy up until refinement!
The gold bearing solution was rinse from flasks that contained gold in solution. The other solution was waste from ferrous sulfate that contained no gold. Ferrous sulfate, dissolve in solution, looks just like a solution that contains gold. In fact, aqua regia, if allowed to sit, will form a yellow to orange color, all by itself with no gold in it at all. This has probably fooled many to think gold was present, just because the solution turned the color of gold in solution - fools liquid gold!
Dear Sreetips If I boil hydrochloric acid and tin to the stannous acid, but the tin is (Sn63a) 63% and there is lead, will it work? or can a process be done before to remove and leave only tin? Thank you
Out of curiosity, I looked a bit deeper. As far as I can tell, if the solution isn't well sealed, it'll will slowly react with oxygen in the air, changing the oxidation state of the tin in solution, rendering it less reactive.
Love your honest, straight up content🇦🇺👍👌

@@sreetips I'll just buy the right one 😊🙏
What strength hydrochloric acid ?
Bottle says 31.45%
@@sreetips Thanks missed that .
Stannous chloride powder work the same ? Or only in crystal form
Stannous chloride powder or crystal should both work fine
@@sreetips thank you sir
👍👍👍
Why does the Stannous Chloride go bad?
Entropy
Out of curiosity, I looked a bit deeper. As far as I can tell, if the solution isn't well sealed, it'll will slowly react with oxygen in the air, changing the oxidation state of the tin in solution, rendering it less reactive.
Keep the dropper bottle well sealed and it lasts for many months.
But always when you open it, you insert a bit of oxygen. Properly sealed it will indeed last very long
Can i send you some dry extractions of gold to refine?
Sorry, I only work on material that my wife and I find at local sales. This is my hobby.
Ahh bummer. Thank you anyways and love the videos. :)
