BigstackD is fun once or twice but his “treasure” is imaginary in terms of real value compared to the money he sunk into it with gas, tools, grinding disks etc. Aluminum bronze etc. are basically base metals. Close to someone stockpiling dirt or old newspapers.
Great part 1&2! The cloudiness comes from AgCl which is soluble in concentrated HCl when pH is very low and the higher the better the solubility of AgCl... when rinsing the filter with distilled water the pH rises and the AgCl comes out of solution. Those microscopic cristalsl of AgCl serve as cristallisation core for the gold when dropping it. You have to either concentrate the gold solution by evaporating most of the remaining HCl and then dilute with water and all the AgCl comes out, then filter and drop the Gold OR you boil the dropped Gold in concentrated HCl several times. But this is not so efficient because inside the gold powder units there is an AgCl core which is liberated when you redissolve the gold... Exolained this in extenso in some of my vids.
I came across your channel by chance about a year ago, absolutely no interest in gold/silver refining, but iv watch every episode you’ve produced since. Thankyou.
I find it fascinating how entertaining this is when you would think it would be so boring. I firmly believe most of that comes from how complete Sreetips is not only in his demonstrations but, most importantly, in his explanations. You could take the contents of his library here on TH-cam and start this up yourself. Glassware to fume hoods is right here.
Thanks for another great, honest video. I have a couple of comments but first my qualifications. I taught chemistry for more than 30 years. The cloudy precipitate is very likely silver chloride IMO. You skipped the inquartation/nitric dissolution step that would have removed the silver for later recovery. The passivated metal you discovered after your first aqua regia dissolution adds further evidence to the silver chloride hypothesis. Easy to be wise after the event of course. Couldn't be sure but the little "tail" at the end of your ingot evidences that some contamination remains in your gold. I see lots of comments regarding recovery of value from your cemented copper. Probably wouldn't be cost effective unless there are some precious metals retained in this copper but an electrolytic refining step for copper might be worth considering. Thanks again for your videos. I really enjoy them.
I watched both from the beginning and when you calculated the 2.5% in, I kept hoping for more. I saw there was a lot of silver in so I got some of my hope up but the weigh-in at the end made this worthwhile, 2700 is better than 2000 dollars, especially with all that work.
I’ve been watching Sreetips for the past year and even if I don’t refine any gold, I find it highly interesting. Very eloquent man, humble in his mistakes and very educational. Continue the great job Sreetips!!
The best videos of refining out there. I looked at some of your videos a year back I think but even more and nobody can match you, your efficiency and professionality ;) Keep doing the great job you are doing ;)
Love the come-back part! Old prof used to make us put a section at the end of our projects (there is a name for it that escapes me) that was specific on what went wrong. His opinion, and I totally agree, is that errors are where half of learning takes place. Books are ouststanding base sources of what others have found, but when you screw something up and can figure out how and why you pump up you own knowledge base and gain confidence to step further out. Or something like that.
Thank you for taking so much of your time to make these videos. There’s nothing else like this (what you do) anywhere else. Your work is appreciated very much.
This is truly amazing. The skill set you have with the trial and error is really enjoyable to see. Thank you for making these videos for all of us. God Bless.
I love how deliberate you are in your movements while dealing with these highly corrosive chemicals. I’m a clumsy bull in a China shop and would not attempt this even if I had the knowledge which I don’t, but it’s great to see someone with your skill, make scrap metal into something highly valuable.
It looks like you were battling silver or lead, or both. Your filtered solution would turn cloudy from the water you had used to wet the filter papers prior to filtering and the water used to rise the papers afterwards. Not that it needs to be identified but if whether or not the white contaminant turns purple in sunlight, this could prove useful under certain circumstances. Next time, instead of repeatedly filtering, start over again by getting all the solution back into a single vessel, add hydrochloric to drop any silver, add sulfuric to drop any lead, let sit for a half hour or so, preferably chilled, then do the filtering. No need to be shy with the hydrochloric and sulfuric in this situation, won't hurt a thing, so be generous. It looked as if you were using distilled during the filtering process, if you had been using tap it would have dropped even more of the contaminant out of solution.
Don't throw away copper. For startes all scrap metal refiners will take it of you and pay you for it. At $6-7000 the metric tonne it's still somthing to consider. $3-3.50 a pond. It can help cover some of the cost and maybe you cud make an arrangement with them to swap for thing you need like zink ect. Same for lead . They are still precious metals and highly sort after. Thank you by the way for not cutting out the mistake. It helps the learning process.
It appears that some of your material may have been Carat scrap instead of gold filled. Remember that crown left over in the un-dissolved leftovers? Please show us a video if what you recover from that leftover material. Thanks!
This was a very educating video, thank you sir! Could you make another video about your waste treatment process in the future? Especially about the time and resources it takes to deal with the waste solutions after you reclaimed the traces of precious metals in your stock pot? This is a very important step of your work wich some people might not know about or appreciate enough due to how important it is to the whole refining process.
I do enjoy your videos. My father would let me do some precious metal refining in the backyard. I mostly did silver scrap but did study and try some gold computer scrap. My setup was a few flasks and plastic buckets. He would come out and ask me what I was doing and then go back inside after I explained. You might try Refining Gold with Dibutyl Carbitol to separate the gold solution from persistent contamination. Oxalic acid as a final precipitation agent is supposed to yield high purity gold.
At this moment, even if that bar is only 23k, it's worth US $2,569.90 at scrap value. At 24k it would be worth $2,681.64. Good job, Sr. I really like how you keep your "uh ohs!" in there to show what to do. I always roll my eyes when I see people make mistakes and then fail to tell you what they did to correct it or even explain what the mistake was in the first place.
You ever figure out what the impurity was that was following the gold over? Awesome attention to detail and craft on your part by the way. Just beautiful to watch you work and have your thorough explanations as well as you not being afraid to show a mistake and use it as a teaching/learning point.
Seems like every time we get a Gold Filled Scrap video the final yield is always more than expected. Also curious about what those pieces of metal that didn't go into solution were.
It's time to get you an XRF. I watch enough of your videos to throw in 10-20 bucks for one just to satisfy my (and your) curiosity. Set up a Patreon for an XRF.
Most refiners, dealers, and jewelers will be perfectly content calling that a "pure, 24k gold bar" Not Sreetips tho! The man has such high standards for his gold that he'll feel forced to refine it, at least once more, before stamping his name on it. 👍👍👍🤩
Would you call the bar .998 fine gold? It sure looked pure. It had a nice look at the pour!! I think it would be cool to see one of the bars that you call really pure or .999 fine assayed. Just to see what it is. I think most would not be surprised to see that most of your bars are .9999 fine. Maybe you like to be safe with your estimates and keep it a grade lower so as not to over rate it, to be safe! Great video Sreetips!! Have a Great Day My Friend!!!
Awesome video , so if you melted down the initial pile of foils instead of dissolving them into solution for further refinement would you essentially have 12-14k gold ? Perhaps taking one last look to clear out potential missed steel bits and stones ? So every step beyond that is refining the gold further through continued cycles of dissolving precipitation and filtration ? Thanks
Awesome video and a beautiful bar at the end. I'm curious as to why you took a different route this time instead of encourting your gold with silver like you did for the $47,000 bar.
I find it fascinating that you find it fascinating by adding a chemical to gold bearing solution to precipitate the gold out of the solution. I find it fascinating that YOU can take a metal that never oxidizes, make it oxidize, and turn it into a liquid. Truly amazing!
I just want to comment thanks for ur honesty and not misleading people! I say that to say this there are a lot of videos out there saying that you can basically use urea to denounce nitric acid all it does is lower the pH wasting money maybe you can help me why these people are misleading people?
I use sedimentation in a measuring cylinder to remove fine sludge from AR. It takes longer, but the AR is then absolutely clean. Maybe it's a solution for someone who doesn't have vacuum filtration.
Guessing silver chloride followed all the way through. It is a real nightmare to get out. Almost impossible with regular filter paper. Clear condition was probably because excess nitric redissolve the silver in first filtration but there wasn't enough free nitric in the other redissolves... just my guess from an experience or three.
I always enjoy your videos sreetips. Your glassware is always extremely clean. Can you do a video sharing what cleaners you use, special brushes or other cleaning tricks. I find keeping my filter flasks clean can be a challenge. Thanks!
Screetips recover copper to and make bar, the price of copper will drop with electric car etc... You coukd make a video of making cooper bar with cemented cooper
A very short video. Just melt & pour. But what might be interesting would be to then electrolize the copper bar and then analyze the remaining slime (if any). Any precious metals left would indicate a 'leak' in his refining process. Given how carefully Streetips checks with stannous chloride, I rather doubt it. But it might be worth the effort just as a check. Of course it would be quicker to just use Mosssbaur spectroscopy. :)
Watched again.. maybe 3 or 4 times? 😋 Because.. I’ve been worried (ever so slightly worried) because I often get about .03/3% yield on 12k GF scrap. The numbers never perfectly add up. Just processed 412g of clean 12k gf scrap.. yielding 12.7g.. (.031 or 3.1%) The numbers: 412 * .05 (1/20) * .5 (12k) = 10.3g = (.025 or 2.5%) You have refined GF scrap many times now, is this also your findings? 3 is way better than 2.5.. thus very lightly worried 🤓 Thanks Sreetips ✌️PT
It varies depending on the material being processed. Watch cases and gf bracelets tend to have a little more yield than pins, rings and chains. But watch cases that are heavily worn through down to the brass will yield slightly less.
Hey Sreetips, Thank you for another awesome and insightful video. I have quite a bit of GF scrap saved up and have been scouring every resource to find a Nitric acid alternative method of processing. Any thoughts on how this could be achived with the same level of efficiency as Nitric Acid? Many thanks.
And now , because I've watched many of your videos and have been a subscriber , you've given me the courage to think about trying this on my own . Thanks much from s.w. Michigan .
I diluted my pregnant solution three times with cold water to crash out AgCL then filtered impurities and dropped 30g of pure gold today with SMB. Precipitate was incredibly fine and settled into an extremely dense mud. I washed with hot water a few times but on boiling in dilute HCL I had extremely violent bumping and was worried about losses or breakage. I abandoned this step and decided to melt as is. Anyone experience this violent bumping and have a way to avoid? Thanks in advance and stay safe!
Steam bump. I experienced the same thing. Just turn the heat down to avoid it. The solids on the bottom create hot spots to form, then release abruptly, propelling solids and liquid up and out of the beaker. Good thing I had mine covered or else the inside of my fume hood would be coated in liquid gold.
@@sreetips thanks for the speedy reply sreetips and yes it was so violent I thought the glass might break! I thought something had gone wrong as visually I didn't think I had 30g but it was very compact. In your experience does dropping gold from a more concentrated solution give courser gold less likely to settle and bump?
In a recent video I had 4 ounces that looked like 2 ounces. Kind of stressful because it looks like you got ripped off. Then after the melt the weight is all there. Not sure what causes it.
@@sreetips Exactly! I abandoned the second AR refinement as I thought I screwed up. I read on the forum that strong AR can dissolve AgCl so I diluted heavily with water before filtering and SMBing. I guess fine gold is good for the first refinement then drop from stronger pregnant solution the second time to facilitate courser gold and easier boiling with HCl.
Where do you get acid from? That’s a huge cost factor for me when I refine. Also, where did you get those glass acid containers with the name of the acid in the glass? Those are nice 👍🏻.
My guess on the cloudiness is the lead... You use sulfuric acid to precipitate it out... I would suggest not running the solution back through the same papers in cases like this... It will help that micro-particulate matter get removed from the solution rather than let some get pulled back through. Just a thought. Either way, nice lookin' bar! 😍🤑💛
@J Fz In my cleanups the centrifuge will make clear solutions when filtering fails. Usually the clear liquid contains the gold. If the pellet in the centrifuge tube is the desired product, it is usually ready to wash after removing the supernate.
@@unh0lyav3ng3r8 I have one centrifuge that can hold 4 tubes of 50ml each. You can spin, clean, refill and continue all day long. The need for filter paper is all but eliminated.
I’m sure that bar is 99% pure, maybe not four 9’s fine but you’re really just splitting hairs at that point. It’s a couple dollars difference in the end. I know that’s the standard for pure gold I’m just saying...
I figure you lost 2-3 grams to waste solutions and have another 5 grams in the scrap that didn’t dissolve. 50 grams not bad for gold filled scrap. Nice work and video bud.
very intriguing series of videos. nicely narrated & explained. my ONLY critiques are that the gloves used are not suitable for working with these corrosive liquids. imho the gloves should have had at least an 8 inch cuff to protect his arms. second critique is when he added the acid to the water and not water to the acid. but all in all, an instructive and entertaining video series.
I have plenty of clean copper that I bought for cheap. No need to invest time that I could use to get caught up on my precious metals. I’m so far behind on metals that are worth thousands per pound. I don’t think I have enough days on earth to get it all done
@@sreetips I'm America we are naive. Our currency has been king as long as we can remember. Mike Maloney taught me the difference between money and currency a few years back. I am adjusting my portfolio accordingly
We can use this to our advantage - not in the rigged financial markets - but on the street when dealing with regular people. People will sell you their gold at a discount, sometimes a very large discount, simply because they don’t understand the value of owning and holding gold. It’s a gold buyers paradise at yard sales, thrift stores, resales shops, consignment stores, flea markets and estate sales. As long as gold price is held low by our friends in high places, then this will continue - I paid off my house last year from the gold we bought. But when it gets away from them, and it will, and there is a big spike in the price of gold (this will inevitably happen) then we won’t be able to find it any more. Those who understand this will do well. Those who don’t will be left holding a bag of worthless dollars. Good luck!
@@sreetips Well said 100% and thanks for the info. The stock market has ruined me financially. I am 34 years old but it's clear what's coming around the corner. I'm making moves right now to hold more and more precious metals. Your videos are great and I'm memorizing the methods of extraction that you show. I should have took Mike Maloneys advice some years back. I would have been well off if I did. But I have a never quit mentality so I'm adjusting and learning. Thanks for your replies your videos are great.
@@hiddentruth1982 yep, me too. Sreetips talked briefly about this in one of the stockpot vids. The iron drops everything, but the copper already dropped the value metals, so all that's left is base. I don't do smelting, but I would guess that copper contaminated with zinc, nickel, lead and random stuff would be unhealthy to melt. Sreetips has said it's not worth it to him to recover and purify the copper, since he gets it cheap at yard sales. Still fascinating stuff to learn though, right?
"I just throw the copper away"
Somewhere, bigstackD just felt a wave of sadness.
BigstackD is fun once or twice but his “treasure” is imaginary in terms of real value compared to the money he sunk into it with gas, tools, grinding disks etc.

He doesnt do it to make money. He isnt into recovering precious metals, just recycling what would otherwise end up in a landfill.

This put me to sleep, woke up a hour later and he’s now washing mud in another beaker.
Damn that tiny little bar is just shy of $3,000 USD , crazy
The chemicals and process probably ate a decent chunk of that profit.
I'm sure that he could have skipped 30 stages and precipitations and saved himself $2990 and around 600 gallons of acid into the environment
I think he probably just likes to pour stuff,,, he was at the gold mud at least six times beforehand ffs,,,,,,,,,,,,,
It's also very clean and fine.
Thank you for taking so much of your time to make these videos. There’s nothing else like this (what you do) anywhere else. Your work is appreciated very much.

Correct

Yes

But it might be worth the effort just as a check. Of course it would be quicker to just use Mosssbaur spectroscopy. :)
That copper is highly contaminated with zinc, lead, iron etc. Would be cost prohibitive and time consuming to purify it.
Dang near $1,900 in todays dollars. 👀 👏 👏 👏
Have you ever done a tour of your shop? I'd love to see how much glass wear you have.

Watched again.. maybe 3 or 4 times? 😋
Because.. I’ve been worried (ever so slightly worried) because I often get about .03/3% yield on 12k GF scrap.
The numbers never perfectly add up.
Just processed 412g of clean 12k gf scrap.. yielding 12.7g.. (.031 or 3.1%)
The numbers:
412 * .05 (1/20) * .5 (12k) = 10.3g = (.025 or 2.5%)
You have refined GF scrap many times now, is this also your findings?
3 is way better than 2.5.. thus very lightly worried 🤓
Thanks Sreetips
✌️PT
It varies depending on the material being processed. Watch cases and gf bracelets tend to have a little more yield than pins, rings and chains. But watch cases that are heavily worn through down to the brass will yield slightly less.
Hey Sreetips, Thank you for another awesome and insightful video. I have quite a bit of GF scrap saved up and have been scouring every resource to find a Nitric acid alternative method of processing. Any thoughts on how this could be achived with the same level of efficiency as Nitric Acid? Many thanks.
Maybe a sulfuric acid stripping cell - but I’ve never tried it with GF scrap
@@sreetips Many thanks.
Excellent video, sreetips! Great as always in your work. I'm looking forward to see the Platinum Refining video part 3.
Got it coming up soon
I enjoy every video. Thank you
And we never get tired of watching you precipitate the gold powder my friend .
Me neither
And now , because I've watched many of your videos and have been a subscriber , you've given me the courage to think about trying this on my own . Thanks much from s.w. Michigan .
I diluted my pregnant solution three times with cold water to crash out AgCL then filtered impurities and dropped 30g of pure gold today with SMB. Precipitate was incredibly fine and settled into an extremely dense mud. I washed with hot water a few times but on boiling in dilute HCL I had extremely violent bumping and was worried about losses or breakage. I abandoned this step and decided to melt as is. Anyone experience this violent bumping and have a way to avoid? Thanks in advance and stay safe!
Steam bump. I experienced the same thing. Just turn the heat down to avoid it. The solids on the bottom create hot spots to form, then release abruptly, propelling solids and liquid up and out of the beaker. Good thing I had mine covered or else the inside of my fume hood would be coated in liquid gold.
@@sreetips thanks for the speedy reply sreetips and yes it was so violent I thought the glass might break! I thought something had gone wrong as visually I didn't think I had 30g but it was very compact. In your experience does dropping gold from a more concentrated solution give courser gold less likely to settle and bump?
In a recent video I had 4 ounces that looked like 2 ounces. Kind of stressful because it looks like you got ripped off. Then after the melt the weight is all there. Not sure what causes it.
@@sreetips Exactly! I abandoned the second AR refinement as I thought I screwed up. I read on the forum that strong AR can dissolve AgCl so I diluted heavily with water before filtering and SMBing. I guess fine gold is good for the first refinement then drop from stronger pregnant solution the second time to facilitate courser gold and easier boiling with HCl.
Wow! Beautiful gold!!!

Where do you get acid from? That’s a huge cost factor for me when I refine. Also, where did you get those glass acid containers with the name of the acid in the glass? Those are nice 👍🏻.
GFS Chemicals. Bought the glass on eBay. The Wheaton drip tip containers from a lab glass supply place - can’t remember the name
@@sreetips Yea youve got some sweet glassware Mr. S
I'm sure it's very pure ... I mean how much did you spend on all the acids!!!!! 😂
Sir, my dirty agua regia solution, copper, brass and gold pure green color.. Not settile in sodium metabisulfite.. How collect my gold
My guess on the cloudiness is the lead... You use sulfuric acid to precipitate it out... I would suggest not running the solution back through the same papers in cases like this... It will help that micro-particulate matter get removed from the solution rather than let some get pulled back through. Just a thought. Either way, nice lookin' bar! 😍🤑💛
Yeah, new filter paper each time
I'm very glad this process is not that toxic
I just say it again..That headmike is such an improvement... So relaxing.much more hobbylike.
It sounds better than the mike you use with editing.
Or do I hear a wall with editing?
no its some kind of 12 mm board with wallpaper or such.
I’ll try the wireless plugged in to the pc and bypass the pc mic next time to see if it sounds better. Probably will
I have been using a small centrifuge to pull down all of the sediments.
@J Fz In my cleanups the centrifuge will make clear solutions when filtering fails. Usually the clear liquid contains the gold. If the pellet in the centrifuge tube is the desired product, it is usually ready to wash after removing the supernate.
@@sanmarzano can you do it with the volume of gold solution he has at the end?
@@unh0lyav3ng3r8 I have one centrifuge that can hold 4 tubes of 50ml each. You can spin, clean, refill and continue all day long. The need for filter paper is all but eliminated.
Great job sir.from Ur experience what is following this gold silver or pt group.
Always use a magnetic stirrer when heating liquids
I’m sure that bar is 99% pure, maybe not four 9’s fine but you’re really just splitting hairs at that point. It’s a couple dollars difference in the end. I know that’s the standard for pure gold I’m just saying...
Agree
REMINDS ME OF BREAKING BAD!!!
Glad you included the warts and all, shows your character in a big way. (Also how to salvage a minor booboo) 🤣🤣
Wow ~ A lot of work, fantastic! Great job...:~)
I figure you lost 2-3 grams to waste solutions and have another 5 grams in the scrap that didn’t dissolve. 50 grams not bad for gold filled scrap. Nice work and video bud.
What do you do with your reclaimed gold?
Sell some
Love watching these videos..
Very very beautiful gold.
Good job my freind.
very intriguing series of videos. nicely narrated & explained. my ONLY critiques are that the gloves used are not suitable for working with these corrosive liquids. imho the gloves should have had at least an 8 inch cuff to protect his arms. second critique is when he added the acid to the water and not water to the acid. but all in all, an instructive and entertaining video series.
Thank you
@@sreetips you are welcome, Sir! but the thanks goes to you for your service. 👍👍👊👊
Throw the copper away?
Not me.. reuse it for stock pot copper 🤗
✌️PT
I have plenty of clean copper that I bought for cheap. No need to invest time that I could use to get caught up on my precious metals. I’m so far behind on metals that are worth thousands per pound. I don’t think I have enough days on earth to get it all done
@@sreetips understand
Gold is money. Everything else is debt -- JP MORGAN
People think that paper dollars are more valuable than gold. Clueless.
@@sreetips I'm America we are naive. Our currency has been king as long as we can remember. Mike Maloney taught me the difference between money and currency a few years back. I am adjusting my portfolio accordingly
We can use this to our advantage - not in the rigged financial markets - but on the street when dealing with regular people. People will sell you their gold at a discount, sometimes a very large discount, simply because they don’t understand the value of owning and holding gold. It’s a gold buyers paradise at yard sales, thrift stores, resales shops, consignment stores, flea markets and estate sales. As long as gold price is held low by our friends in high places, then this will continue - I paid off my house last year from the gold we bought. But when it gets away from them, and it will, and there is a big spike in the price of gold (this will inevitably happen) then we won’t be able to find it any more. Those who understand this will do well. Those who don’t will be left holding a bag of worthless dollars. Good luck!
@@sreetips Well said 100% and thanks for the info. The stock market has ruined me financially. I am 34 years old but it's clear what's coming around the corner. I'm making moves right now to hold more and more precious metals. Your videos are great and I'm memorizing the methods of extraction that you show. I should have took Mike Maloneys advice some years back. I would have been well off if I did. But I have a never quit mentality so I'm adjusting and learning. Thanks for your replies your videos are great.
Are you related to John C McGinley? You sound&look a lot alike. Excellent informative video.
Save the Copper Sreetips. 5 dollar a kilo I guess. I've heard in bars it's even more worth than scrap.
Breaking Bad
Copper is worth money as well. You shouldn't throw it away
you could melt the copper in to bars and sell them to a scrap yard for 2 bucks a pound. it's not much but it adds up.
It would cost more than that to refine it. That is why it is $crap.
@@TheLemzia true but he has already refined it in the process of getting the gold and silver when he puts the iron in to the stock pot.
@@hiddentruth1982 nope, it's contaminated with everything below copper in the reactivity series tin, lead etc.
@@rickthefatman8426 ah, I've never done any of it so I don't really know. that's why I ask and make suggestions is to learn.
@@hiddentruth1982 yep, me too. Sreetips talked briefly about this in one of the stockpot vids. The iron drops everything, but the copper already dropped the value metals, so all that's left is base. I don't do smelting, but I would guess that copper contaminated with zinc, nickel, lead and random stuff would be unhealthy to melt. Sreetips has said it's not worth it to him to recover and purify the copper, since he gets it cheap at yard sales. Still fascinating stuff to learn though, right?
