Sr. Chief, if I could go back 30 years with what you’ve taught here on your wonderfully informative channel, I’d be writing this from my own private island! Great stuff, Sr. Chief! 👍👍👊👊
I just want to say thank you Sreetips your professionalism and very detailed processes. They have led me starting to recover and refine gold as well as silver. I just ran my first batch of GF material last week. 200g led to 7g button 3.5% yield! All thanks to you! I’ve been watching you for years and I can’t wait for the next video!
GF material is readily obtained for 1/2 pennies on the dollar! Way to go. Explaining to the folks you are buying it from what is actually in it can be hard as it is just as shiny as 10k gold and if it is also plated with 23k they might think you are attempting to scam them, be careful, let them watch your determination of what it is... offer to test any other jewelry they might think is too good to be sold so cheap. Carry a spare loop, it will serve you well... get lucky and have fun. Use the testing solutions and the scratch plate, watch the jaws drop!
I've done a few computer scrap refines so far, using nitric acid substitute in powder form, and I have a small 10gram nugget, but it represents a ton of work and fun. Getting through the excess nitric acid issue was tough at first but the tip of adding very little at a time was perfect. Looking forward to my next scrap refinement :) Thank you Sreetips!
@@rhf5448 friends, family and dumpster diving. Profit? If you salvage all gold from the boards you can have enough to drop maybe like 15$ on refinement but the scrap yard will give you money for copper, heat sinks, fan motors, motherboards, and any other precious electronics. So overall, yes lots of profit but from gold? Definitely not considering the hundreds of hours I’ve put in for a 750$ chunk of gold nugget
Stretips is the best no doubt! He is the heavy weight refiner Champ of the World!🏆 I had to refine a huge 1 pound nugget.. It took me forever.. I got it done tho! My refinement process is a Geo Metro & Stretips refinement process is a Rolls Royce🏅🏅🏅 Great work as always! God Bless you and Mrs Stretips!🙏🏆🙏🏅🏅🏅💎
I watch a few different forgers of raw metals, people who melt it to form bars or coins for storage. You are by far the most meticulous and interactive of them all. I try to never miss one of your videos. Keep the great content flowing.
I would love to send you a little bit of gold that i got from a creek in central Illinois area it took me 6 hours to find less that a quarter gram lolol it isn't much but you have brought me years of entertainment and education
Awesome Sreetips I look forward all week for your videos . I'm a diehard fan of yours . I've even saved every video you have done to my phone . So if Wifi ever goes out I still have something interesting to watch. 👍👍👍
Another great video, your ebay recomendation for a fume hood and extractor was much appreciated, all i need now is my own Mrs. Sreetips, but GF material will suffice for now.
I saw after precipitation and rinsing, after boiling in HCL, boil in water, then ammonia to further scrube any copper off. Always seems to look great with the ammonia boil
Cold Ammonia in janitorial strength works well enough to part the fractional copper remaining after all the nitric boils but will add another waste stream to the process which will not play well with the initial waste treatment usually suggested -cementing silver with copper. If doing this pour the cold ammonia rinses into a different catchment system. Since elemental silver does not dissolve well in frigid or icy cold ammonia direct treatment of that waste stream with iron is preferred. Ionic silver will readily be dissolved in even cold ammonia and since a part of the remaining silver is present as ions of nitric you will lose that portion, hence the reason to treat that waste stream separately for the cement vs ammonia parted at the very end. A little goes a long way and can be beneficial if you do not care about the fractional silver present after all the boils in HLC H2O. You will be able to see the silver oxide form as a dark grey to black coating which will vary depending on the fraction of silver present after all those rinses. This can be removed with hot Dilute HLC. It will shine your nitric parted gold inquart as you say...
Mr scientific again I'm going to put abouuuuuuuuut that much, Love your lingo! Hey when you remove the silver from the inquarted gold and the gold looks dull, can you bring the brightness back to that gold in that form?
Can you explain the quarting the gold with the silver? I have no clue what’s going on have the time, but from watching you, I always thought you add the silver to make it into Karat gold or lower karat. Seeing the scrap was already karat gold would it not have Silver or enough silver in it to put the gold into solution and perceptate it out? Thanks
Inquart: adding enough sterling silver or clean copper, to create an alloy that is 1/4 pure gold, and 3/4 silver and base metals. With the gold content of the alloy this low (25% or 6k) the nitric acid can now penetrate each piece to its core, forming a honeycomb structure as it goes, to completely remove all the silver and all the base metals. Inquarting with silver and parting with hot dilute nitric is a recovery technique. Once all the silver and base metals are removed, we can then refine the gold with Aqua Regia. Recover and refining are two totally different processes.
Es wäre interessant zu wissen, wieviel Gold, Silber und andere kostbaren Metalle sich auf dem Boden und in der Werkstatt von Sreetips befinden. Eine kompletter Reinigung würde sicher einiges zu Tage bringen. Hoffentlich kommt mal eine Sondersendung dazu.
Wen you spilled some of that gold powder in that one video I was like ohh 😂😂 bro wen you swept that up 😂😂😂 very cool !!! I metal detect and find tons of jewelry I started watching you a while back trying to learn😂 and wat I learned is that I'm bright enough to clean up My gold I dig 😂😂😂😂
Would this go faster if the chunks of inquarted gold were much smaller? Like I wonder if this could be reduced to metal powder and then do the nitric washes or would that make the reaction too violent?
Do remember to scrape the cement floor for precious metals. I noticed the thier was quite a bit of over splash to the floor this time. A gram of findings is worth the effort occasionally.
Impure silver is best waterboarded, impure gold not so much. It has to do with the molten metal surface tensions being different... The gold even in very low percentages acts as a surfactant of sorts... The silver likes to ball up but the gold relaxes the solution. The copper in the recovered silver causes the balling to be more prevalent. The heat shows this well in the inquartion melt vessel and the condition of the dirt (anything other than those two metals is dirt even pgms!) all contribute to the solute alloy's ability to "cornflake" on contact with the water. This flat splash and the fragmentation bursts are what you want to increase the surface area of the poured metal alloy. Slush ice works best but it hard to achieve in most casual labs with any ease. Floating ice is ok but not needed. If the pot of water is actively chilled with coils of refrigerant the best results can be obtained. That is way too expensive for a hobbyist unless you are an HVAC manufacturer in your day job. Making shot works best without a waterboard and a greater height. You also heat to well above the alloy ideal temp for the air to fractionally shape to ball type shot. The depth of water needs an increase if your resultant shot is teardrop shaped in any fashion. Shot is for shooters, cornflaking is for refiners. The reason we refiners like flat splashed is for high contact area with control of dissolution and the convenience of the alloy not rolling away while rinseing and such.
He's probably going to refine the silverware anyway so might as well start the process when inquarting gold. At least that's the sense I've gotten from previous videos.
To, "J": You and me both! I started following this incredible guy, two years ago. If we could just go back in time? I'd have an island beside yours! The really incredible thing is, unlike most of what you find on the WEB, SREETIPS is ROCK SOLID! It's hard Science that is repeatable! Since that first Video, I now have my own Laboratory and enjoy every day I'm out, Boiling Metals! All thanks to SREETIPS! A TRUE ROCK STAR! wade
@@sreetips If we know the amount of gold that will be precipitated, and we weigh the amount of SMB before we start the process. Use the SMB, as you usually do, then weight the SMB when you're finished. This will give a ballpark figure to start with.
I just use number of spoons for a specific amount of gold. For example, I know I can get all the gold to drop two ounces with eight spoons of SMB. But it only takes three spoons for an ounce. Why the disparity? Don’t know, it just does.
Hi all, Question for Sreetips, when cooling AR you add ice cubes to cool, dilute, and precip any silver chloride. The precip of the silver chloride is caused by the cooling, dilution, or are you using tap water instead of diH2O ice cubes? Thanks in advance! LOVE the vids! I have learned so much!!!!!
I think i found my answer: Silver Chloride precips out when solution gets down to 50c due to the chlorides in the HCL which is in the AR, correct? Thanks again for the VIDS cant wait for the next!
Silver chloride is slightly soluble in Aqua Regia. More so in hot Aqua Regia. Adding cools the solution and forces the silver chloride out so we can filter it out.
The water splashing out from the tank as I poured the molten metal in only appeared to be metal because it (the water droplets) were being illuminated by the brightness of the torch.
Borax melts. Any contamination will tend to float on top of the molten gold. The molten borax will adhere and pull it off to the side of the melt dish. Also, borax cause the metals to flow into a central mass in the bottom of the melt dish.
After I do the initial nitric boil on my gold filled scrap, I can add karat gold to it when I put it into aqua reiga (latin for, will turn any God dam thing into liquid)?
@sreetips I'm going to try it. Just a couple of pieces of scrap. 10k & 14k earrings. After you do the initial nitric boil you're just left with karat gold, so let's try it.
I was watching an unrelated video a little while back, and the person mentioned that the trick for rosebud tips on torches is to run a slightly oxygen deficient flame and it helps. Not sure what the mix is, or if it will help you or not, but it is worth a try if you haven't tried that.
SMB will tend to drop platinum group metals with the gold powder, if present. But it’s quick easy and cheap. Ferrous sulfate (iron sulfate) will drop the gold, all the gold, and nothing but the gold. So if there are other metals in the gold solution, for high purity, iron sulfate is the precipitant to use. However, ferrous sulfate is cumbersome, bulky (takes a pound of it dissolved in hot water to precipitate two ounces of gold) a little more time consuming that just adding SMB right into the gold solution.
my one question would be: Since by my understanding that Nitric acid is expensive and hard to come by, why aren't you capturing the fumes off the boils and condensing them back to usable chemicals for future extractions?
People selling online know what they have, that’s why they sell it online. We buy from people who don’t want the gold for a number of reasons. Mostly because they need currency to pay some bills. People are clueless about gold and silver. They believe, incorrectly, that paper dollars are more valuable. We buy at local sales. But it won’t just fall in your lap. You’ve got to get up early and be there first. Or else the gold and silver will be long gone by other pickers who understand the true value of GOLD.
@@sreetips I tottaly agree people think that dollar is so high and mighty and that's cool I figured it was probably at some sales but I also kinda figured since they don't know what they have most people might try and over value it but mabey not as for the selling online part would make sense didn't really think about that to mutch
When are you going to take a trip to Australia to do a video with bigstackD casting? He gave you a shoutout a few weeks back. He has a pretty good size following
Nothing like some good old Gold on the Rocks. That aside, I seem to recall that in one of your earlier videos you tried enquarting the gold with copper and that it seemed to be cleaner and easier than with silver, yet you're still using silver.
you can clearly see the water is kicking out material.. maybe hold it lower or use a shroud around it, money, I know you will sweep your floor one rainy day and pickup a nice little bar .. .
What fascinates me about elements like gold and mercury is that their properties like the yellow colour and being soft or liquid is due to immense relativistic effects of the inner electrons being bound so tightly to the superheavy nucleus and forced to speeds so close to speed of light it makes them heavier. Such nucleus could not even be made in an ordinary star - even heating to hundreds of millions of degrees would do nothing to it. Even atomic blast would barely touch it.
Because it a giant pain and the crucible has a tendency to boil over from all the sodium carbonate that must be added. Silver chloride conversion makes three nines silver.
I think my favorite form of the gold is after you inquart the gold and boil of the silver with nitric. I'd probably stop there and just store the gold in a raisin bran or corn flake box. 😂
