Agreed, I almost always know exactly what step comes next(unless he switches it up) down to being able to finish almost all of his sentences. However, for some weird reason I get mad when I have to wait for a video because of the suspense roflmao. Been watching Sreetips for about 2 years now, still suspenseful lol.
@@thesleeperofrlyeh9015 I often watch and enjoy these videos too. I like to second guess what might come next and what I might want to do if I were treating the material. I'd be washing the solids a few times with distilled water, then adding sodium cyanide solution to leach out noble metals but I've never seen Sreetips use cyanide. Cyanide is what is used to extract gold in the mining industry.
I watched someone pour acid on something and an orange cloud came up. I knew immediately that it was nitric acid. This sort of knowledge could save you life.
This is my favorite kind of thriller! Taking the unknown substance and extracting gold from it, like Sherlock Holmes. Please, keep doing it! Although it is not pleasant to perform, it is a hell ton of pleasure to watch.
"Every time I get jeweler scrap, I swear I'm never gonna do it again..." we love your videos. I am in a non gold bearing region however electronic waste is ever present and you have taught me a lot. Thank you so much.
So much work! This is another example of using the pyrometallurgical application of the fire assay analysis. Ignite and screen your sample down to that black powder. Ignite it again. You want to be left with your metals, carbon and abrasives oxides and carbides. Take the black screened material into a fire assay clay pot and fill it about 1/4 of the way up. Add half that volume of CuO. 2 oz of Na2CO3, 1 oz of Na3BO3 1 oz of clean SiO2. Heck. Throw in 5 oz of wheat flour to insure you have enough ignitable carbon. Mix the dry materials. Fire until molten in your furnace. Pour off into a metal cone. Let cool under a metal cover. Break up the glass and collect the Cu button. Repeat until all your initial sample is processed. When the carbon reduces the CuO to Cu metal, the glass formed by the borax, washing soda and sand will absorb the abrasive oxides/carbides. Work up your Cu buttons with your HNO3 boils. It'd be a quantitative collection of all precious metals. The only place you could lose metal value would be in the initial ignition and grinding process. No inquart needed. When you cement out the Ag, it'd be all the Ag in your total sweepage. Maybe some Pd, too! You're left with nothing but metal and glass. If it survives, the crockery can be used over. If it doesn't survive, it can go in the trash. Expect breakage. The glass can be disposed in your local glass recycling, if you wish. You have all the equipment that you need except the fire assay clay pots and CuO. (Chuckle) You can sweep up around your lab table and run that material.
Hearing you describe general good quality jewelry repair as a dying breed reignites the little spark for jewelry craft I have. I'm only 24 but I took a jewelry class in high-school. I loved it, loved it so much I spent almost 600$ buying things to make jewelry but before I could get into it things went sideways in life. I really hope that one day in the future if nothing else that I find myself in a position to pursue jewelry craft again. Thanks as always for the great videos Mr tips.
Such a tease! "What's in the brown mud? Find out in the next instalment!" I really need to be more patient! looking forward to the reveal. Have you ever had a mystery sample analysed in something like a mass spectrometer to know what it was in fact that you were dealing with? Would be a fascinating comparison on mystery substances like this.
Great stuff Sreetips! I started watching, and then thought to myself, "Didn't he swear to never do this again?" Right then you said, "Yes I swore I'd never do this again and yet here we are." 😂😂😂 As the old saying goes, it takes one addict to recognize another. Looking forward to the next in the series. Did you remember to sweep out the furnace? Not that there would be much there.
I got a good feeling about this round Sreetips. That was a very good volatiles burn off and HNO3 separation and the most surface area you could ever ask for. GL&HF!
Thank you for the new video, cannot wait to see how much gold you recover from this! I know it is hard to do, but these kinds of recovery are fun to watch.
You are welcome. Looks like it’s shaping up to be an interesting result. As I watched this from the pacific coast tropics, nearing sunset, I looked up to see a large flying bird that wasn’t a vulture. I was able to get a quick glance through the binoculars and I’m quite sure I had my first known sighting of a Golden eagle (all other sightings, in Canada, can be attributed to being juvenile Bald eagles). That said, I figure it’s a good omen, and soon we’ll see a great golden egg. Thank you Sir!👍👍🤟
Chemical engineer here. When I designed a scrap recovery system, we used tunnel furnaces, which used trays and of material pushed from one end to the other.
Sreetips, you have gained roughly 30k subscribers since I have started watching you. I assume your viewership has gone up and you are hopefully monetized. Anyway, I (I am sure I can speak for most of us here) enjoy your videos and if there is a way I can support you including us in your hobby, I hope you let's us know how.
I say this, because FYI, when you make comments on your videos about how you said "I was never going to do this again", means, this is going to be a damn good video or series of videos. And when you grovel over an incident in a video, it is usually the best part of the video. I don't believe it is because we enjoy your distress, I think it is because some interesting or new just happened and seeing how resolve the issue.... It is just like reading a good book (I would assume).
I've been waiting for 6 days for the last video to come out. Now I'm going to watch all of them at once. Thank you for creating the most unique refining series videos. You are by far the best.
I know you swore to never do jewelers scrap again but I for one am glad you did. These are great to watch - but I sense your pain 😉 Well done sir. Great video 👍
I wonder if this would work similarly to a batch of various scrap electronics I worked on last summer. I didn't have the patience in me to spend the time separating everything out so I just added it all to 400gm of sterling. I figured since I'd know reasonably close the amount of silver I'd get from the sterling that anything extra would have come from the scrap. I can't remember exactly how much scrap I worked but it was over 500gm. All various smd components (ie diodes, transistors, resistors, capacitors, fuses etc). I just melted the sterling and then began adding in scoops of the scrap and let it all melt and alloy. I had to use a LOT of flux though as it kept getting really chunky but when I poured it the flux had a really nice glassy look and separated very well from the prill. Followed that up with nitric acid and there was a surprising amount of black dust left over and most of that was Au. Some Pt which was just poured into the stockpot. I was surprised at how much Ag and Pd I got out of it. More than I expected and this method was (for me at least) much easier than the way I had been doing it previously and far less labour. It'd be interesting the see if doing this would make working this type of material easier to clean out for you. That abrasive has GOT to be a royal pain in the neck.
My dad was army and he used to say if you bite off more than you. Can? Chew just keep grinding till you get that bite small enough to swallow. Always informative can't wait to see the next episode of this.
In place of the repair person paying you for cleaning his equipment, is he giving a percentage of, or giving you in whole what you recover from this? I hope it's the full amount personally. Love the show and the work you do, very fascinating and fun to watch.
More like the other way round, he makes a fuck ton from these videos, if I had this many subs I'd do the jewellers dust for free, just my opinion but he probably does get a cut of the yield.
I was curious what a reasonable percentage is to keep if you are toll refining, not for a friend, with a material that is relatively (ha) straightforward. Theres many variables i suppose. Great series Srretips...
I add this to my special RU-vid unicorn list. This is so pleasing to watch. People that have the pleasure to be close to you are surrounded with blessings all around. What a wonderful human being.
Is this the same jeweler that had the carpet scraps you refined? The guy that eats peanuts at his bench 😃 I know these are insanely time consuming but it’s fascinating the way you process seemingly non-metallic stuff into bars.
Doing cleanup work like this or the carpet from under the workbench always seems like they would be a lot of work, but makes for good content showing all the odd places you might find a surprising amount of gold. I noticed you had different kind of nitric acid bottles. Did you change supplier or did your supplier change the container? If you changed supplier any reasons why?
Missed this video when it uploaded and I'm just now starting to watch it. I'm dumbfounded that this fan is inside the area where all the metal dust is collected! It's probably full of precious metals that can never be recovered!
Mr Sreetips… I just want to introduce myself as an avid lover of the videos you have done. You being a hobbyist gives me real passion to pursue the same joy you are doing… which I hv already invested some into … Having said these things ,.. just as a opinionated answer or answers from you,.. could you please give me and others here any links to some viable” and somewhat cost friendly” sites beyond EBAY,.. that provide purchases of reagents and acids, that can be acquired as a home hobbyist. Particularly on Nitric acid sales and on dry reagents. I am meeting roadblocks as an individual trying to purchase and not as a business. Any input or direction would be so helpful… Ken from Kentucky
I just bought nitric from dudadiesel. All the other stuff I get on eBay or Ace Hardware. If they want a business, then create an LLC. It cost a couple hundred bucks. Any tax accountant can do it for you. A company doesn’t have to be a building with plant and equipment. It’s just a piece of paper in a folder in your file cabinet.
I agree! I transfer it to 1 liter bottles, much easier to handle. Seems like the sources for nitric are getting hard to find. I have made nitric in the past but it is a lot easier and cost effective to buy it.
Have you ever thought of getting a small propane blower burner, some kaowool, fire bricks, crucibles, a cone mold and flux. Rather than struggling with the incinerated mess, just add it to a crucible with a flux compound. Melt it all at once. Pour it into a cone mold and let it cool. All of the precious metals will make there way to the bottom of the mold with the collector metal. Then all you need to do is cupel the lead button and you are left with a nice clean ball of precious metals to further refine. It might save you time, money and headaches.
