It makes me feel better about my dishwashing skills that sometimes gunk is just stubborn. Have solids on a plastic spoon? Pour acid over it, I might think. Some junk just doesn’t want to go. Haha
Love these videos, i am sure its a pain to refine and comes at an expense. But it sure looks like fun to-do and i bet the feeling at the end is amazing. Keep up the good work Sreetips loving the content.
Aaaaaand another cliffhanger. Now I have to re-watch some older sreetips video to feel whole again 🤓 Thanks for all your work and explaining. Best wishes from Germany
Most games that came out since 2007 are a just horrible thanks to Xbox and playstation, everything got so dumbed down. For me the 1990th had the best PC games.
Great video Sreetips. I was NOT expecting you to use purana solution. During the whole video I was waiting for that plastic spoon to melt like in the old bugs bunny cartoons stirring poisonous concoctions 🤣
Excellent video as always! Sreetips, did you see the videos of the nitric spill in Arizona recently? First thing to come to mind was hoping that spill doesnt have any impact on what you are doing! Of course it didn't or wouldn't, it probably wasnt that much that was spilled, but its reaction when spilled was a familiar one!
Just a quick question for ya, Sreetips, does the color of the fumes change depending on the type of acid used/material dissolved? Total layman here that is fascinated by these reactions..
He said 'test this with stannous', and I thought he said "it's Mr. Stannous!" It would be fun if he'd throw in little jokes and started naming very common items. Mr. Stannous, Steve the Stirbar, and all of Sreetips favorite friends!
Hello Mrs and Mr sreetips. Soon weekend, and 2 part of the refining. Hope all who follow sreetips will get a nice weekend. Thanks for sharing sir. Thanks 🌹. Arne
Id be interested to see if you find the piranha treatment to be worthwhile for the filter paper refining? That would potentially save some incineration time, and just filter paper can go super fast in piranha. For this refining, maybe it generates too much waste to be worth it, but idk, I still support the use of piranha elsewhere if it makes economical sense and you think you wouldn’t mind
I think you should use the piranha solution on the last bit and the filters instead of the scoops of pure material. With the possibility of high lead from repairs, it's probably not a bad idea to have it in that sulfuric acid.
Is there a video on this channel of how you got started in all of this? It seems like such specific knowledge that you need to even begin to understand the processes.
Yes, there are many reactions that occur and some of them interact or interfere with others. It is generally recommended that a person download a free copy of C. M. Hoke's book on refining jeweler's waste and read that before doing any experimentation of their own. The book contains acquaintance experiments to help familiarize a person with the basic reactions, processes and tests.
if solution before adding piranha contained excess nitric, adding H2O2 may cause some gold to dissolve. you shold check piranha for gold with stannous. does piranha rinces took some colloidal gold? you should od some aqua regia to rince waste to check it
Because of the Dirty nature of this material, wouldn't a total melt and pour into a Cone mould be more efficient? After the melt, chipping off the slag, leaving you with just the heavy precious metals to chemically refine? I only say that to make it less annoying for you. The slag can be ground up and remelted to get any trace metals, if you're so inclined. Not to get off topic but, if you were to use Aquarigia with the sulfuric dose from the start, wouldn't it eliminate all the sludge more quickly, if you stayed with a pure chemical method? If not for watching you, I wouldn't have even contrived these questions. Thanks for all you do.
He needs to start with nitric acid to dissolve and get out any silver that is likely present. If he were to use aqua regia from the start then the silver would create an extremely fine dust of silver cloride. That dust would clog up any filter and be nearly impossible to get out of the solution with the gold because it is too fine to settle out.
156th! Your videos are so interesting to watch. Once I start, I’ll watch video after video. Brings me back to my time at School of Mines. Roger in Pierre South Dakota
Everything you scooped up from the bench was either precious metal or polishing compound. The compound is wax with a fine grit. The wax is flammable. The grit, depending on type is either glass or diamond dust, maybe steel. Glass melts before gold or silver. Diamond doesn’t melt and steel melts waaay after gold or silver. It seems to me that you could burn off the wax and set up a staged stack melt and let the gold and silver percolate to the bottom and collect in a pool of glass (flux). Does any of this ring true? Am I way off?
Glass melts at 1700°c. Gold melts at 1064°c. This method that exploits metals melting point for separation.... I think it starts with a T. For the life of me I cant remember it. Someone smart... help me out. I think it would be better suited for recovery of lead and tin, but Im certainly no expert. I see where youre going, Sreetips is mostly setup for Hydrometalurgy.
There are folks who know how to add a flux recipe and a collector metal, such as silver or copper, then get it real hot and pour into a cone mold. But I have zero experience with that. So I’ll stick to what I know, the wet chemical process.
Hi, I'm a silversmith and jeweler so it interests me seeing how much you get from the polishing compounds. And can I ask in both videos so far how many hours has the process taken? 🤔Seems very time consuming,but of course gold is worth it 👍🏼haha
I’d be interested to see if using piranha solution on a filter recovery would be better than incinerating the filters, leaving less residue to gum up and hold the gold in like this mud ended up doing.
That’s a good one. But incineration does more than just burn away the paper. It converts any tin that may be present to insoluble tin oxide. Then it can be easily filtered out (so I’ve been told). However, after incineration, and before the nitric boil, hitting the incinerated material with piranha solution my help by dissolving the carbon away and removing the solids, making filtering easier.
@@sreetips oh! Didn’t know that part about the tin. I wonder if the tin would oxidize in the solution with all that H2O2. I’d love to see a mini series on a test of both pre/post incineration
In Hokes book it does mention to use one method or the other. Youv reduced the organic matter to Carbon by incineration, I am unsure whether Caustic Soda will have a meaningful effect on this. The Pirahna Solution will turn the Carbon to Carbon Dioxide, so is conceivably beneficial. I hope youre a trained chemist and you absolutely school me right now...
@@NOFX0890 haha no… that’s where I read about the method also (but obviously can’t remember the details). I tried it on my own incinerated jewellers waste and it removed most of the remaining crud… but I decided it was too dangerous even on a tiny scale and now give the ash to the refiner.
Loving the series so far. For materials that are highly contaminated like these, I wonder if it would be easier to reduce your volume of working material by smelting first for the recovery phase and then refining. Jason over Mount Baker Mining and Metals might be interested for the next go around if that was even an applicable solution.
Splitting the sample up and doing a comparison of the processes would be very interesting. I’m sure Jason would be up for it and something many would enjoy seeing. Great idea!
Haha, I just commented about the same thing. Full melt into a Cone mould, than just deal with the clean stuff. Stops likes doing it mostly chemically, but this stuff is nasty.
Dunnow why but this is a funny episode. at 10 min mark now...why not test the pirahna (rinse) solution with stannous? could even do a nitric titration after that and check if Precious metal particles came over with the rinse.
That’s been tried. I couldn’t get a good result. Others with more experience, adding a collector metal for example, may be able to pull it off. But for me, it’s the wet chemical process that I’m familiar with.
I am NOT going to skip to the end this time. Lets go BOBBING stuff! Finished edit That juice looks thick to me. In my molar ignorance, I'm going to guess 15.8g of gold if a single refining of the good stuff.
If you don't mind I can suggest other RUclips channels to you, something like this ruclips.net/video/mvmWGM3QqEU/видео.html a guy that bought a mine with a ghost town.AvE is a fun Canadian, bigclive is in to circuit boards.

I'm always in awe of your patiient editing, and your clean presentation.
Thanks for that.
Can't wait to see how much of the "gunk" turns out to be precious metals and how much was just polishing stone. Great work so far 👏
Enjoying this series very much! You Sir are a personal inspiration to me. Keep up the videos and amazing work!
It makes me feel better about my dishwashing skills that sometimes gunk is just stubborn.

Man, you are so tenacious. You don't give up and struggle through. Every body could learn from you
I didn't even know piranha solution existed. Everyday is a school day. Thanks Sreetips.
It was a pleasure to watch the process continue. You’re hustling through this material like a peregrine going after a pigeon! Lol! Thank you Sir!👍👍🤟

Gooood evening from central Florida! Hope everyone has a great night!
Goooood evening!
Excellent video as always thank you 😊 🙏 👍
Sure will be interesting to see how much gold and silver comes out of that solution. These reactions are always fascinating. 👍
Thank you for another great video!
Thanks for sharing this with us as always ❤️
Very interesting approach I like it. There must be a way to simplify the process as much as possible.
When Sreetips reaches for the piranha solution you know it’s a tough job
Awesome video sreetips can’t wait to see how much gold you get out of the jewellers bobbing

Yes, we recognize the red/brown gas. Seen it a hundred times.
I've made a playlist with the videos I have yet to watch. This is a very interesting series.
Always a good day when Sreetips posts!
Very interesting and informative I believe that you will get a very nice amount of gold and silver from this. Six stars brother

Just a quick question for ya, Sreetips, does the color of the fumes change depending on the type of acid used/material dissolved?
Total layman here that is fascinated by these reactions..
Yes. See Sreetip's various videos where he discusses this.
Mostly red/brown fumes with nitric
Almost forgot all about part 2. Was very curious of how much gold you would get from all of that.

Keep watching and learn.
@Mike Connery I'm not really talking about learning, I'm talking about a video where he talks more about himself.

At this stage I'm always thinking what a mess, how is Sreetips going to clean this up into .999 fine gold but you always do!! 👍👍
His stuff is always very difficult.
When I saw the notification, I put it on and turn the TV up as loud as it would go to drowned out. My daughter yelling at her kids.
Real quick question for you sir! Ever had a serious spill that has either hurt/Injured you or set you back weeks worth of effort? I’m curious to know.
His first stock pot video series includes a major spillage that took several videos to recover. He dropped the entire pgm-bucket IIRC.
Excellent.
I like the dark color on the test paper

In Hokes book it does mention to use one method or the other.
