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 CZcams and start this up yourself. Glassware to fume hoods is right here.
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.
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.
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.
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 ;)
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!!
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.
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.
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!
Another great video @sreetips and a nice looking bar at the end. 👍👍 Any afterthoughts on what might've been following the gold through the refining process ?
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 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!
So awesome to watch your videos again I really look forward to them thank you. How long do you think untill we find out what's all hiding in your stock pots and filters?
Wow that looks nice and clean I love it I have some gold about 1oz are more And it has some Aluminum in it that fell in the kiln while melting the gold down Is there a way of getting it out Thanks
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.
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.
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.
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.
Another question if you dont mind Sir....If you dont have an oven can you just incinerate the material you captured in the filter with a torch? Or would there be a reason you would absolutely have to do it in an oven other than convenience?
Suggestion. I used glass funnels as lids. A 600 ml and 1000 ml. Just set them in the top of the beaker. You never need to pick them up and you can add fluid via the funnel
I love your videos and am at the very begginer of jewelry manufacturing and refining. I found in my search that if youa don't want to pay outrageous for your gold inventory it's best to try and find the the carated gold and gold filled scrap. I get where to find gold filled items but where do you find the gold carat for refining and resell. Any info would be greatly appreciated. I have 1500 grams of gold filled so far and all the real carat gold I found even scrap is way over charged on ebay and the other selling sites. Any help would be very useful.
Yard sales, thrift store, resale shops, consignment stores, flea markets, estate sales. Got to get up early and be there first or the gold will be gone. People on eBay know what they have and want top dollar - eBay is not a good place to buy gold. You can’t sit on your computer, in your pajamas, and expect to buy gold online at a discount. However, you can find it at deep discounts at the aforementioned places if you know when, where and what to look for. Most people believe, incorrectly, that paper dollars are more valuable than gold. We can use this misconception to buy gold at a discount. But it’s not going to fall in your lap. You must hunt. Good luck.
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 .
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!
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.
What is the cost of your refining effort, between scrap jewelry, chemicals, and disposal of waste products? Could the cloudiness be from the impurities in the stump out and Iron fertilizer?
Hey sreetips can you remind me what those dark fumes are? Also, I love your videos. Learning alot and am collecting some scrap to refine my own gold and silver 👍🏻 love how you make safety a priority, much respect
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.
I have a question I know you do a distilled water and nitric bath to get rid of the base metals would using hydrochloric acid and hydrogen peroxide not also work??
So when the copper cements out on the iron, is it replacing the iron or does the iron stay the same, still an angle iron and relatively the same amount of iron? And if it just plates out on the iron, after the entire surface of the angle iron is covered with copper, does the cementation stop?
Please see “reactivity series of metals” the copper “cements” out on the iron as the iron goes into solution. The two metals trade places. Once the reaction is done, I’ll have metallic copper in an acidic iron solution.
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?
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.
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 👍🏻.
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 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.
Aluminum bronze etc. are basically base metals. Close to someone stockpiling dirt or old newspapers.
He doesnt do it to make money. He isnt into recovering precious metals, just recycling what would otherwise end up in a landfill.
@@cjwinther1658 His "treasure" is CZcams views. ;)
@@cjwinther1658 he still would surpass costs, he gets bunch of money from youtube doing it and its a hobby. Why not
bigstackD! He used to pretend to melt his wifes fancy faucets, door knobs, screens or whatever. lol
My favorite part was when he realized it was more gold than he was expecting. It's always fun to realize you have more gold than you're expecting.
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...

its quite wonderful when you add your nitric to your HCl and gold and see it spring to life with that fizzing and gorgeous yellow colour
I love the yellow clear solution, but I also love watching the SMB precipitate the gold out. What a beautiful process.

Thanks for the great vid Chief, absolutely riveting.
Great stuff Chief. Way awesome. When I retire in 10 years I'll be doing a lot of this type of stuff. Currently an OS1. Thanks for the great content
The Navy was good to me, and I was good to the Navy.
We never get tired of watching your stuff. Keep 'em coming. Best health and luck to you, Sreetips.
Was really looking forward to seeing this second part!
This put me to sleep, woke up a hour later and he’s now washing mud in another beaker.
Still enjoying the chemistry absolutely phenomenal yield of your gold

Freaking awesome videos brother love watching u recover gold and silver!!
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.
Thats awesome. Good job. Beautiful bar.

Great job sir.from Ur experience what is following this gold silver or pt group.

Sometimes it remains a mystery.
Silver or lead maybe?.
Do you think it would be less expensive to make your own assets or buy them?
BTW thanks for your videos.
I think I will start refining soon.
Great stuff, as ever. 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.
If I remember correctly, that was refined from karat gold, not gold filled scrap.
great videos (pt 1 and 2). Thank you for sharing. How do you dispose of all of the acid solutions.
Waste treatment
Like the chemistry behind it
Always use a magnetic stirrer when heating liquids
Another question if you dont mind Sir....If you dont have an oven can you just incinerate the material you captured in the filter with a torch? Or would there be a reason you would absolutely have to do it in an oven other than convenience?
I’ve used a torch, but the flame will blow material out of the dish.
So this is how they make Mt Dew.
Great job, great result! 👍

Not all gold filled material is marked
Just subscribed, fascinating. How much did the handful of gold filled jewelry initially cost?
I don’t keep track of each batch. That’s about 6 months worth of accumulation. My wife finds it for me at local sales
Can't wait for the silver refining video next!
And we never get tired of watching you precipitate the gold powder my friend .

With gold scrap jewellery isn't there way easier to refine it? With using Electrolysed? With polling out copper?
Not that I know of - getting pure gold is never quick and easy
Gotta know what kind of watch are you wearing in the video ?
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.
That is a beautiful little gold bar
Glad you included the warts and all, shows your character in a big way. (Also how to salvage a minor booboo) 🤣🤣
Bro you need to do a CCD setup for your bench...batching is so tedious!!
How much does the supplies cost to get an ounce of gold or silver on average?
I have a question I know you do a distilled water and nitric bath to get rid of the base metals would using hydrochloric acid and hydrogen peroxide not also work??
Possibly, but I’ve never tried it
at 11:45, where does the green color come from? it is oxidized copper in solution?
Where does one get these acids? I pull gold pins from scraping electronics
So when the copper cements out on the iron, is it replacing the iron or does the iron stay the same, still an angle iron and relatively the same amount of iron? And if it just plates out on the iron, after the entire surface of the angle iron is covered with copper, does the cementation stop?

Very very beautiful gold.
Good job my freind.
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.
Most gold filled material is 1/20 12k or 2.5% by weight. But watch cases and older bangle bracelets can be up over 4% by weight

Oh yea, that’s the good stuff!
@@sreetips Hahaha right! Watched you do this for a good while now man, few years at least, love the process it's fun science, thanks a ton!!
A lot of people I watch mix the aqua regia before adding it to gold. I think you add the nitric acid separately. Have you tried doing both?
Yes, I have a video on it. Premixing guarantees problems during precipitation and wastes chemicals.
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
@sreetips why not melt the copper into bars and reuse it to cement your silver?
Because it’s contaminated with other metals.
Very interesting, a lot of work and effort but definitely worth the results 👍
I bet a light source behind the beaker would show a lot more detail from the precipitation.
Excellent suggestion, thank you. Watch for it in my next gold refining video.
Wow ~ A lot of work, fantastic! Great job...:~)
