Chief, I like how you keep going over the steps. Not in a "you are so stupid way", either. Just "this is how you do it and why". Very methodical and precise. Familiarity breeds contempt is not your style. Bravo.
You have so many angles figured out with these processes you've found a way to maximize efficiency and limit waste of costly acids. So much knowledge and experience you give for free!
This is why it's crucial to rinse the gold well with several distilled water boils and not just cold rinses prior to aqua regia. Distilled water boils are able to rinse the gold and remove the remaining base metal nitrates much better within the honeycomb structure, resulting in the cleanest gold possible before proceeding to aqua regia, which is the ultimate goal of base metal removal. As you say, the more time we spend in the base metal removal process, the fewer complications we encounter in the gold refining process. This theory also applies when it comes to rinsing the gold prior to aqua regia. This is very important! Other than that, great video Mr Sreetips! Nice looking bar! Thank you!
Love watching you refine the gold and I like watching you recover the silver for your silver crystalizer lolol you gonna need a lot of silver for your HP looking forward to many many more refining and silver pores especially when you get enough silver if you ever decide to poor a big 30 to 60 pound bar lolol woooo that's wishful thinking lolol I only say that because I got to see a 60 pound bar of silver and a 66 pound bar of gold love your vids SREETIPS number 1 refining channel I've ever watched God bless
Thankyou once again for these wonderful tutorials. I’m obsessed with this chemistry. Your knowledge has kept me intrigued for a long time and I just wish I could put it too good use.
wondering if a large anode "puck", formed in a melt dish, with a 90 degree from the center out copper spiral shape, would be well suited for the larger silver cell?
I love how streetips makes refining look so simple... 👏 And man that silver cell is looking extremely impressive and putting the old anodes into the silver shot to keep the "hot" anode out of the solution brilliant idea👍 Like always thanks Streetips
I know this will sound weird, but I've watched so much of your chemistry/electro chemistry that I can tell the purity of your gold by the color and clarity of your gold in nitric solution. Always enjoy all of your content!
It never gets boring, nothing prettier than a huge blob of molten gold, especially in person watching it melt, I LOVE GOLD, But not more than my Dog Lol.
Very well done sir! For a single refining with no frosting on the bar, you could easily stamp that 3 nines fine! CM Hoke would be applauding you for this! At this point I feel you could write an updated version of her book with modern techniques and revisions and would sell 100K copies.
Hey @Sreetips. Love your work. Had a bit of an idea... See if you could consider pulling it off. So the total amount of (above ground) gold on the earth is estimated to be equivalent of a cube of gold with a side of 21.4m. Therefore, if you made a cube of side 2.14cm, you'd have a scale model 1 to a billion, of the imagined cube of all the gold we've ever mined... and you'd have 'exactly' a billionth of the earth's gold in one awesome little cube. It would be hard to do, I'm sure. But you're the man to pull it off! Wylis
Very nice bud. Do let Momma Sreetips 😮 see you drop that gold bar into the cool water bowl without a wash cloth in it. You're denting and marring up the final product 😊
Current value of this bar is around £6600 gbp. Would be nice to know what you paid roughly for all the gold plus what you have left in value with the diamond and Tiffany necklace etc
I watched part 1 as well, but forgot to hit the like button. Got a question for you sir. I noticed you use distilled water to rinse your beakers, are the ice cubes you use made of distilled water as well ? I am asking because of the minerals in tap water,, and am thinking those minerals would contaminate the solution. Anyways, I love watching these videos. It is always a pleasure to watch someone who knows what they are doing and why, and also have the capability to pass that info along.
Should dilute with more water after evaporating excess nitric acid. Make solution less syrupy so gold don’t get stuck to filter also kick nitric silver out of and make easier to filter. Making second refining easier
Congratulations from Brazil Mr. Sreetips, your videos are awesome! As an old subscriber that is following your work for many years I would like to ask you if possible for a video showing again your waste tratament where you after cemented the silver, you cement the copper with iron, and melt this cemented copper in a bar... I know that the value of the copper is low and you usually avoid work with it, but i believe that it would be a interesting content.
Hey, I was wondering - There is an Australian melter called BigStackD, who has a whole lot of silver connectors from various electronic and electric devices. I know from his videos he's also a viewer of Your craft. I am fully aware that You're a gold refiner, but could You please consider doing a video about harvesting and extracting silver from the silver connectors, as sort of a guide? This could be both an interesting series and help for those who want to try Your craft to recover precious metals.
@@sreetips I'm still gratefull for the lead demonstration video, although I thought You did go overboard with the amount XD Love the engagement and will wait for the next videos. You did inspire me to try my own shot at amateur jewellery making, especially with melting and pouring metal over plaster molds.
Isn’t it true! Every time we do anything against our normal “this is why we do it this way” routine we end up getting reminded why… in reference to the filter paper failing the the full suction
How long can the gold stay in its liquid form? Can it evaporate, or is it stable? (I ask because it would be cool to hide your gold in plain sight -- like in a bottle with an apple juice label on it, for instance -- in the fridge or someplace like that. Probably a silly idea, but that's how my oddball mind works.)
That’s totally possible. In liquid form it should keep indefinitely. Or it could be evaporated to dryness to form burnt-orange chloroauric acid crystals. Those will last indefinitely and can be rehydrated with hydrochloric acid and a little heat.
Would it be worth the time to break up the gold sponge after you have done maybe 5 nitric boils to break up the gold more to give it more contact with new surfaces to make sure all your nitric boils are effective? It seems you waste a lot of good nitric on the 5th and beyond boils because it doesn’t seem to consume all the nitric to take the silver and base metals out. Maybe instead of pouring those off, you give it a stir and move the gold around some to break up the sponge. Is that even possible?
It would be very interesting to know the exact purity of your cement silver once it's melted. The Silver shot doesn't look silver colored at all. Sterling Even at 92.5% silver (7.5% copper) has a silver color to it. You silver shot looks very copper colored, more like 75 to 80% Silver. Just for kicks or maybe for video content, you should send some of your melted cement silver to get it analyzed for exact purity contents.
Wow! Again, this is an awesome video out of curiosity. Would it be easier and cheaper to use just copper instead of silver, or would it create more problems than it is worth as gold amalgam already has silver content, and I would assume the silver content would hold a very small yield and can you still use SMG to precipitate the gold out or would you have to use something else, love your videos
I’ve used copper instead of sterling and got excellent results. But I refine silver so for me it’s best to use sterling. I’m refining both metals simultaneously. SMB works with gold inquarted with copper
I used to have a hard time remembering whether anode or cathode is positive/negative. Now I can’t say “anode” without thinking “basket”, so I can’t forget.
I have a question, I was watching a old video about getting gold from a bottle of catches but you had a problem with springs, the question is that could you possible have a carbon fiber mesh be used as a filter to filter out the gold from the catches as I believe carbon fibers resistance to heat is higher than that of gold
Hello Sreepips, What happens if you add the cement silver directly to the anode basket instead of melting it first? Wouldn't it be easier and faster to purify silver in powder form? Thanks.
There's a new BBC article on "India's army of gold refiners face new competition", and there's a sentence at the end saying: "They are moving away from using nitric acid to purify gold, instead switching to Aqua Regia, which is less polluting." I was thinking, "Hey, I understood that reference!", thanks to these videos. It must mean that previously they had been doing the nitric acid boils on inquarted material, and now they are dissolving the gold instead. I'm not sure, if it was really meant to say that they are doing this as an alternative, rather than to reach an even higher purity which they are talking about in the next sentence, given what we learned here that #1 dissolving scrap gold-filled material in Aqua Regia is a no-go, because too much is wasted, and #2 the more dangerous fumes come from the second method, even with incremental dosing of nitric. And no masks on the guys in the photo. Although the photo is about the melting, which is the most photogenic part, of course.
Karat gold can be dissolved straight away in aqua regia. But two nasty problems can happen. 1) it will put everything in solution, creating a very dirty solution. And there will be a lot of silver chloride that slows filtering. 2) passivation. If the silver content in the karat scrap is high then the hydrochloric in the aqua regia with react with the silver in the karat gold, form a hard crust of silver chloride on the karat gold, and shield it from the acids. It must be scraped off before anymore gold will dissolve. But of course, the passive layer of silver chloride will re-form and scraping must be repeated. Both of these problems are completely eliminated by first inquarting with silver (or clean copper) then parting my with nitric BEFORE going to aqua regia. Inquarting is the easier softer way.
I keep thinking If it was not more advantagous to pour a bar of inquarted gold and stretch it between rollers before submitting it to the nitric boils. The nitric acid would not have to penetrante as deep as into the large, irregularly shape chunks of.shot. This might save on time and nitric acid expended.
I tried it once. Having to fight with the rollers, annealing the bar repeatedly. It was just too much. I’d rather let the torch do all that work for me.
@@sreetips I understand, alloys are always harder than their constituents and tend to work harden as well. I'm always fascinated by your work. I am a retired chemistry lab assistant, I understand the chemistry behind your work but have never worked with precious metals myself. Greetings from Berlin, Germany.
Awesome video, I know you cement all the silver out of your solution, do you ever try to get your copper back, would just stand to reason to re-use the copper as well, I know its not that expensive but could resource this metal as well, thanks for another great video!!!
I don’t know. Evaporating until all the fumes are gone, and the excess nitric gets expelled. I don’t know the chemistry/physics of how it works. It just does.
Sreetips, I'm curious about wether there's a way to grow gold crystals as the result of a refining process which would net pure fine gold crystals and could one induce, by temperature, saturation, or maybe voltage, a single large solid faceted crystal of gold to grow...?🤔
HEY SREETIPS ITs MIKE . I got a question when I dissolve my gold sponge and aqua Regia and it boils does some of the gold get lost due to the evaporation or not because I have a clock dish covering the beaker and what I noticed is that the yellow color drips down back to the beaker is the gold mixed with the steam?
Yes, some of the gold will depart in the finely atomized droplets that get ejected from the beaker. Covering with a watch glass will minimize it. Even better is to heat it gently so that it doesn’t boil. It’s the turbulence from the boiling action that causes atomized droplets to form. Reducing heat so that the solution doesn’t boil is by far the better option. I always boil mine because I’m in a hurry and in a rush to publish my video. Don’t do as I do, do as I say and you’ll be fine. Reduce the heat. Even then you’ll probably still see yellow liquid condense on your watch glass cover. There are losses all along the way. Minimizing them will depend on the skill and technique used by the refiner. If I wasn’t making videos I’d probably do a lot of things different. When that camera is running I’m tensed up and tend to make errors. I’m going to refine a batch of karat gold later this weekend. And I’m not going to shoot video of it. I’m putting the camera away, taking it nice and slow, and try to regain some of the enjoyment I used to get practicing my hobby, like it was before I started using that pesky camera. Be like taking a breath of fresh air.
He uses distilled water to make his ice cubes. Tap water would add too many contaminants that would then have to be purified from the gold, and in some cases could be quite difficult to purify from the gold.
Chief, I like how you keep going over the steps. Not in a "you are so stupid way", either. Just "this is how you do it and why". Very methodical and precise. Familiarity breeds contempt is not your style. Bravo.
Yes, that's my take on it too
Also you never know who’s watching for the first time.
Thank you
I wholeheartly agree - I learned more about non-oganic chemistry from Sreetips in a shorter time than 6 years of middle and high school.
He came off rough around the edges when I started watching but I came to realize this myself over the years as I’ve watched his videos.

I did the tests before and after. I just didn’t include them in the edit.
@@sreetips awww I knew you would as your a pro my brother..👍
Have you ever tried putting the freshly poured bar (still in the form) in a preheated oven, to finish the bar to a smooth high lustre? No pour marks.
Getting the mold that hot would quickly ruin the graphite mold. Plus, I’m kind of partial to the pour lines.

If it looks like that when u melt it it’s way under 99 to 98 percent too much copper
Perfect you showed us how smart you are great job.
What are you referring to? The gold or the silver.
Isn’t it true! Every time we do anything against our normal “this is why we do it this way” routine we end up getting reminded why… in reference to the filter paper failing the the full suction
I was trying to pull it through faster to save time. Ends up costing me more time. Murphy’s Law.
Sir could you get a weight on how heavy the solution is before your put the gold back into solution and after plz ty
Hey Mr sreetips, why don't you break up the gold when dissolving out the silver? The gold looks more like brown nuggets than a powder.
Because it will produce very fine powdered gold, or worse, colloidal gold that makes separating the silver solution from the gold more difficult.
How long can the gold stay in its liquid form? Can it evaporate, or is it stable? (I ask because it would be cool to hide your gold in plain sight -- like in a bottle with an apple juice label on it, for instance -- in the fridge or someplace like that. Probably a silly idea, but that's how my oddball mind works.)
That’s totally possible. In liquid form it should keep indefinitely. Or it could be evaporated to dryness to form burnt-orange chloroauric acid crystals. Those will last indefinitely and can be rehydrated with hydrochloric acid and a little heat.

All I saw when you moved the crucible to the melt table was nice big ol Nugs, lol.
I’d love to be able to find some gold in the creek out by my house lol
I know there’s some on my back yard. But it’s parts per billion.
Would it be worth the time to break up the gold sponge after you have done maybe 5 nitric boils to break up the gold more to give it more contact with new surfaces to make sure all your nitric boils are effective?

Maybe instead of pouring those off, you give it a stir and move the gold around some to break up the sponge. Is that even possible?
No. Breaking it up during nitric boils will cause fine gold powder that suspends and takes time to settle and slows things way down.

Always forget to ask. The ice cubes are they distilled water ice cubes or regular ice cubes ? You never say. So curious
Tap water

No, probably some karat gold that was light on gold - it happens all the time.
One day I'd love to precipitating gold out of solution with spoonfulls of SMB. #lifegoals 👍👍
Can you inquart with copper next time ? Is it possible to inquart with other metals ?
Yes

You should try insulating the mold.

Don’t do as I do, do as I say and you’ll be fine. Reduce the heat. Even then you’ll probably still see yellow liquid condense on your watch glass cover. There are losses all along the way. Minimizing them will depend on the skill and technique used by the refiner. If I wasn’t making videos I’d probably do a lot of things different. When that camera is running I’m tensed up and tend to make errors. I’m going to refine a batch of karat gold later this weekend. And I’m not going to shoot video of it. I’m putting the camera away, taking it nice and slow, and try to regain some of the enjoyment I used to get practicing my hobby, like it was before I started using that pesky camera. Be like taking a breath of fresh air.
P.s tell Teresa HAPPY MOTHERS DAY from me and Maggie your loyal viewers. ❤️❤️❤️❤️
Happy Mother’s Day!
You really should have tested that last (9th) nitric boil solution for silver.
There was some silver left, it came out when u added ice. But it’s easy to filter out.
So what byproducts are in the "gold refining waste" flask? Platinum group or a mix?
Traces of PGMs. But mostly suspended gold from the rinses.
Could you estimate the amount of silver in solution by calculating the density?
Possibly, but I’ve never done that.
Hey Sreetips when you add ice cubes into the gold solution are you using tap water or distilled water in the cubes?
He uses distilled water to make his ice cubes. Tap water would add too many contaminants that would then have to be purified from the gold, and in some cases could be quite difficult to purify from the gold.
Tap water
no stannous test!?! 😲
