I watched your last refining video like this several years ago and was absorbed in the process of refining gold, this is an amazing series and i llove that it was like 2x the size of the first bar you did in your first video, very entertaining to interested people and great to see the end result, beautiful. I dont know what you spent on all the scrap but im sure through the many days/weeks of work put into this that you got more than your money back in money spent and time spent back in cold hard cash with that bar. Excellent work Sir.
I wish you were my science teacher at school. I could listen to you all day hahaha. I was also on the edge of my seat when it was time to precipitate the gold wow. Thanks so much for what you doing. 👍🏼
I was so excited for this. I so enjoy watching the process... It's just so very exciting... I am bitin at the bit for the next episode!!!!! See ya tomorrow luv!!!!
>"Who in their right mind would try to refine 25 ounces of gold in a small setup like I've got here? Good Lord..." You said it, not me. I was seriously squeamish watching you one-hand those beakers at some parts. But of all the people I can think of who could pull it off...
Doing great sir! Thank you so much for taking us along on your journey of refining metals. Yours is one of my favorite channels. This is a real sanctuary, away from all the BS going on, political crap, dire news, pandemics, and squabbling of the internet.
*sreetips* You are indeed a wizard, I'd end up blowing up half the mountain we live on. Thank-you sir for taking the time to bring us along. God Bless.
Yeah, he is - and here's the real magic: @2:29 his gloves magically change from off-white welder's gloves to yellow general purpose gloves. Now, that's what I call a real magic! ;-)
I hate to give my 'teacher' a suggestion but I dilute the chlororic acid 3:1 in cold distilled water before filtration. This step also helps dilute any residual nitric that may still be present. Hope this helps....
That powder looks awesome..absolutely loving this series, and now you've left us with a cliff hanger finale :-D no matter what happens it's ALL good Sreetips, thank you.
I love the video, your attention to detail, and retrospective analysis of possible errors. I kept thinking a small batch centrifuge would remove cloudiness quickly and efficiently.
I have just finished refining 120g of pure gold and posted some pictures on the gold refining forum. Many thanks for the videos, made the process much easier!
I been watching you for a while and although this is your biggest batch you have it well in hand. thank you for putting up content that is not only interesting but very educational keep it comming.
"Nobody in their right mind..." You are apologizing while putting on the best show on RUclips. I am waiting for you to put together the Colt 45 of videos. A forty ounce!!! Nice work super chief!!
Working on three videos almost simultaneously right now; Low Grade Sweeps Pt2, Furnace Build for large melts, and some escrap. Plus I’ve decided to refine the 7 ounces of gold from the inquartation video a few days ago. I’m getting spread too thin.
Great video as always! Can't wait for the grand finale! I would love to hold a pure gold bar of this size just once in my life. Just to say I've held one.
Oh wow! Been looking forward to see the pour... Waiting for part5 now. Can I just ask... At this stage will a second aqua regia treatment get rid of that cloudiness that we saw in the final solution? And would it get the metal in a finer state or would it be pointless to do a second aqua regia?
The mad scientist is no longer experimenting. You make mistakes and are able to get yourself out of trouble and make it look easy. That’s a PRO! Congrats!! Doing what you love and making money in retirement. Flat out awesome! I’m happy for you and Mrs Tips.
I have sat here watching every single part of this process. Unfortunately I saw the last one first then became curious. This is pretty amazing!! Bravo Zulu!!
I’m pretty new to this Chanel, and I really think you’re doing a fantastic job explaining how this stuff works. My kids are a little young to understand what’s happening, but they really like the end results! I’m pretty sure they think I should have a lab of my own.
Since you know that some gold went over into that bottle, does it make sense to treat that beaker before you add to the stockpot? Or is there just not enough to go after...
Did 10oz once and that was at my max comfort level sreetips it is hard handaling that much in 2L of solution and i have also made the mistake with a burnt out solution and adding Hcl to it and getting a boil over. Also gold plated a beaker when dropping a large amount of gold because the beaker was not clean enough.
I'm a new subscriber and really do enjoy watching the process you go through to refine gold. My question is how do you think it was possible for the Egyptian culture to create such beautiful treasures out of gold even if they didn't have the advanced knowledge that you do? After seeing what all you have gone through I have a more complete appreciation for Egyptian antiques.
Urea is no longer used by modern refiners. If too much nitric is suspected we add sulfamic acid to kill it. Or just add a little extra SMB until all the excess nitric gets consumed.
I'm still watching my way through All of your videos in about 6 months and I'll be caught up. I'm watching videos you posted a year ago as opposed to 4 years ago
I had a bunch of old computer scrap that I processed. When I did the SMB drop the temperature of the solution was about 68F degrees, and fell to 38F degrees with no ice. I then heated the solution again to about 80F, and the gold then precipitated completely. Any clue to as why this happened in my case?
That was a smart decision to do another nitric boil on that gold. Love your videos. I never get tired of watching these videos. Alot of valuable information you are teaching people. Thank you sreetips. Edit: looks like I spoke too soon. Solution was a little cloudy but regardless, it was a good choice to do another boil.
Chlorine in tap water instantly forms silver chloride if it’s added to a silver nitrate solution. But not chloroauric acid because it’s a chloride. When working with silver nitrate always use distilled water to avoid forming silver chloride.
No, I’m working in a fume hood. All the vapors get drawn away from me as I work. If I can smell odors from these reactions, then that is a big problem. Working in a fume hood enables me to safely process the metals. Think of it this way; you would not work on your car inside a closed garage with the motor running.
So this looks very, very fun, but I'm wondering if it's sustainably profitable. With the cost of all the chemicals, equipment, karat gold, etc. do you make enough off of it to keep it going? Or are you having to supplement the project financially? Also do they give you full spot price for the bar or do they discount it because it's a home refinery.
Cant wait for the next video. Does the quality of distilled water very by company? I know that regular bottled water can very from company to company. What is your favorite company water to use. I noticed this time you been using Piggly Wiggly.
Hi, i think you heard many compliments, so everything said is little for these informative entertaining videos. Keep it up! I have only one question, i am always afraid from the fumes of nitric acid, some times i ask myself did i smell allot did i burned my lung!, i know you're working under a fume hood, but with all these qualities of fumes, nothing reaches your nose? Because i see you sometimes pouring nitric acid outside the fume hood, can you tell us your experience with these fumes?
Good video man. Do you have enough filters and waste paper stored to do a refine that would be worth it? Or even your waste chemicals? Love those videos too
He did one quite recently where he used his past few years worth of collected waste filters and such things, might be a while before we see another one
Hello streetips let me start by saying i love watching your work it really is fantastic my 9 year old son watched you as well and we were wondering would there be something that you could do in the future that i would be able to do with my son as a fun home experiment. Now i do live in the UK and like yourself i am a vetran of the Royal Air Force i was a sniper so when it comes to science i am a bit lost but i would love to be able to do something with my son. I completely understand if you can't tho but please keep up the good work. Will
I always comment on the color and that chloroauric acid is _rich._ Easy to tell by the depth of the orange. Fun fact: Solid chloroauric acid is soluble in water. Thanks, Senior! One more run and the bar. Can't wait.
hello Professor, how long do you leave the waste AquaRegia along with the copper in your stock pot?So that precious metals are cemented out. And How long should i leave copper to cement the precious metals in my nitric acid waste stock pot. Should I add more small doses of nitric acid when I notice that all the acid has been consumed? Thanks , for me you are the best.
I allow the stock pot to bubble for about a week. Then I remove the bubbler and check it for remaining pieces of copper with a glass rod. If yes, them I’m good and I let it settle for a few days, decant into my waste treatment bucket and add more waste. If no then I add some copper and bubble it some more.
As far as copper in silver, most of the silver will cement out over night. But I stir it good with the copper in to release any silver nitrate trapped in the silver powder and let it set another day. Sometimes it sits for days before I can get to it
I wish that could. But this is my hobby. I don’t keep track of expenses for each batch. I keep records for taxes, but it only gets figured once for everything at the end of the year.
@@sreetips Thank you so much. Would the addition of zinc and subsequent smelting form an amalgum with the silver and zinc to eliminate the lead be a valid means of recovering the silver, or is there a simpler method of recovering the silver at that point? Thanks for your response.
Nobody in this segment cooler and more informative than the LIVIN' LEGEND : Screetips !!

Amazing, I love your content and your detailed explanations! Very informative and fun to watch!👍😎👊
Been looking forward to this pour

I’m check them out.
Watching your videos is so satisfying and enlightening experience.
Great video. No matter how many times I see this part of the process I love it. That was a lot of SMB. But you did it.
I been watching you for a while and although this is your biggest batch you have it well in hand. thank you for putting up content that is not only interesting but very educational keep it comming.

Thank you Sreetips for the quality content ! 👍
Sreetips has officially graduated from "bars" to "bullion"
Thank you, these videos were great, I'm looking forward to more of your videos.
Working on three videos almost simultaneously right now; Low Grade Sweeps Pt2, Furnace Build for large melts, and some escrap. Plus I’ve decided to refine the 7 ounces of gold from the inquartation video a few days ago. I’m getting spread too thin.
Sreetips, the gold standard in making refining videos. Great series!
Great video as always! Can't wait for the grand finale! I would love to hold a pure gold bar of this size just once in my life. Just to say I've held one.
I always get a thrill when the smb causes that dark rain of gold! Awesome, Sir!
thanks again for the upload sreetips, happy to see part 4

Love youre videos
Got a question tho....
why dont you boil down the ar,and add hcl (two times or so)to get rid of the exess nitric?
When you add ice to precipitate the gold do you use distilled water to make ice? Thanks you are a great help. I have had some bad experiences.
The mad scientist is no longer experimenting. You make mistakes and are able to get yourself out of trouble and make it look easy. That’s a PRO! Congrats!! Doing what you love and making money in retirement. Flat out awesome! I’m happy for you and Mrs Tips.
Cannot wait to the grand finale with this video you have answered a lot of my questions that I have such amazing educational
Good stuff! Have you ever tried using Urea to consume excess Nitric before using SMB to precipitate?
I was worried about that cloudiness but Steetips pulled through :)
Great videos. Do you have a contingency plan for dropping $47000 of solution on the floor... a new mop and bucket?
I have sat here watching every single part of this process. Unfortunately I saw the last one first then became curious. This is pretty amazing!! Bravo Zulu!!
BZ!
I’m pretty new to this Chanel, and I really think you’re doing a fantastic job explaining how this stuff works. My kids are a little young to understand what’s happening, but they really like the end results! I’m pretty sure they think I should have a lab of my own.
Keen to see the final phase. I can't wait to get into doing this!
Very cool series! A monster amount of gold. I bet your second refining will be even better.
do you release each part as its done or do you wait for it to be completed then release each part?
Since you know that some gold went over into that bottle, does it make sense to treat that beaker before you add to the stockpot? Or is there just not enough to go after...
This is an awesome series sreetips 👍🏽
I look forward to every instalment...
Just found this channel. Love this guy. So many casserole dishes.
Welcome and thank you!
Did 10oz once and that was at my max comfort level sreetips it is hard handaling that much in 2L of solution and i have also made the mistake with a burnt out solution and adding Hcl to it and getting a boil over. Also gold plated a beaker when dropping a large amount of gold because the beaker was not clean enough.
thanks for sharing man... appreciate ya
Sreetips and Walter White were my #1 inspirations to wanting to be chemists. Keep up the good work!
Awesome at one point I thought oh its going wrong but you recovered from that and it looks good now
Always fun to watch kevin. Thanks a bunch .. from Ewaste Solutions Sonny....
Thank you ESS
I never get tired of seeing the reactions and percipitations.
I'm a new subscriber and really do enjoy watching the process you go through to refine gold. My question is how do you think it was possible for the Egyptian culture to create such beautiful treasures out of gold even if they didn't have the advanced knowledge that you do? After seeing what all you have gone through I have a more complete appreciation for Egyptian antiques.
Egyptians were mining and panning pure gold along the Nile. I think they just had to pretty much heat it up.
Good luck mr. Sreetips, and be healthy our dear friend.
Amazing video Sreetips
Well done Chief, attacking it like a pro.
Do refiners still add urea to consume excess nitric acid in gold bearing solutions? I remember reading about it years ago.
Urea is no longer used by modern refiners. If too much nitric is suspected we add sulfamic acid to kill it. Or just add a little extra SMB until all the excess nitric gets consumed.
I'm still watching my way through All of your videos in about 6 months and I'll be caught up. I'm watching videos you posted a year ago as opposed to 4 years ago
how much did you used sodium metabisulfite for every gram of gold recovered?
That's awesome you answered my question with out thinking bout it yupp my gold is pure like yours thanks guy your da greatest
sreetips... easily one of my favourite things to watch on youTube (or anyting else!). Thank you for the awesome content!
Love how you easily follow your instincts
another excellent chemistry lesson!
Hi sir please can u tell me what difference does it make to inquart the gold with copper rather then silver
Copper takes more nitric than silver. I use silver because I refine silver.
What was the cost of chemicals and consumables from start to end...?
I had a bunch of old computer scrap that I processed. When I did the SMB drop the temperature of the solution was about 68F degrees, and fell to 38F degrees with no ice. I then heated the solution again to about 80F, and the gold then precipitated completely. Any clue to as why this happened in my case?
None
Been waiting for pt 5 for days
Can't wait for pt 5!
Hey sreetips, why was it necessary to add the refined gold shot to the solution? Thanks man, I really enjoy your channel.
To increase the size of the final bat
So what would be the solution to if you drop the jar of liquid gold on the floor how do you recover that, asking for a friend
How do you make sure that you do not add too much Sodium Metabisulfite?
That is beautiful I understand your concern.
Thank you, professor.
That was a smart decision to do another nitric boil on that gold. Love your videos. I never get tired of watching these videos. Alot of valuable information you are teaching people. Thank you sreetips.
Edit: looks like I spoke too soon. Solution was a little cloudy but regardless, it was a good choice to do another boil.
Why is last video private? Was looking forward to it so much.
just to verify, tap water ice cubes at this point are fine? any chlorine in the water would just precipitate AgCl correct?
Chlorine in tap water instantly forms silver chloride if it’s added to a silver nitrate solution. But not chloroauric acid because it’s a chloride. When working with silver nitrate always use distilled water to avoid forming silver chloride.
@@sreetips yup for sure
What do the various acids and solutions smell like? I know you arent like breathing it in intentionally, but it must leave behind some odor, right?
No, I’m working in a fume hood. All the vapors get drawn away from me as I work. If I can smell odors from these reactions, then that is a big problem. Working in a fume hood enables me to safely process the metals. Think of it this way; you would not work on your car inside a closed garage with the motor running.

That Pour will be unprecedented! I’ve been dying to so you pour large quantities.
It's cool how high the ice floats in that extremely dense liquid.
Hi, i think you heard many compliments, so everything said is little for these informative entertaining videos. Keep it up!
I have only one question, i am always afraid from the fumes of nitric acid, some times i ask myself did i smell allot did i burned my lung!, i know you're working under a fume hood, but with all these qualities of fumes, nothing reaches your nose? Because i see you sometimes pouring nitric acid outside the fume hood, can you tell us your experience with these fumes?
Nitric will dissolve tooth enamel. I get a whiff every now and then.
@sreetips oh! That's what i face from nitric acid, but sure, i have 1% experience in front of you :). Did you experience any respiration symptoms?
Every time you pour into a new container, I hold my breath, lol ☮️
Good video man. Do you have enough filters and waste paper stored to do a refine that would be worth it? Or even your waste chemicals? Love those videos too
He did one quite recently where he used his past few years worth of collected waste filters and such things, might be a while before we see another one
@@JeffJeffers0n :(
so glad you did that last nitric boi; Your gold will be really pure now.
Which machine u used for mealting.. plz send me the detail ABT that
I think it was Kerr electro melt
Have you done a refinery process with gold filled wire ?
I’ve done gold filled material

I always comment on the color and that chloroauric acid is _rich._ Easy to tell by the depth of the orange.
Fun fact: Solid chloroauric acid is soluble in water.
Thanks, Senior! One more run and the bar. Can't wait.
When gold is in that form, does it register on a metal detector? Ive become enthralled in your channel.
I don’t know
What was the grey sediment ? Is it silver chloride ? Could it be the reason why you ended up lacking Hcl ?
Both distinct possibilities
hello Professor, how long do you leave the waste AquaRegia along with the copper in your stock pot?So that precious metals are cemented out.
And
How long should i leave copper to cement the precious metals in my nitric acid waste stock pot. Should I add more small doses of nitric acid when I notice that all the acid has been consumed?

As far as copper in silver, most of the silver will cement out over night. But I stir it good with the copper in to release any silver nitrate trapped in the silver powder and let it set another day. Sometimes it sits for days before I can get to it
@@sreetips thanks professor.
hooked on this stuff.
Have you tried reducing the volume of waste water solution by evaporating first so it takes up less space in the container
Yes, evaporation is very useful in reducing the volume of waste.
Would definitely like to see a cost breakdown on this in the final video
I wish that could. But this is my hobby. I don’t keep track of expenses for each batch. I keep records for taxes, but it only gets figured once for everything at the end of the year.
When you ran the solution through the filter, was the residue Silver Chloride?
Yes, most likely but there may have been lead sulfate as well
@@sreetips Thank you so much. Would the addition of zinc and subsequent smelting form an amalgum with the silver and zinc to eliminate the lead be a valid means of recovering the silver, or is there a simpler method of recovering the silver at that point? Thanks for your response.
Hi sreetips can you do a video extraction gold out of sand with hci then scooping up the honey and making it to a bar 24 k
isn't urea a good way to denox nitric? DEF diesel fluid is urea and deionized water. $11 at the auto parts store for 2.5 gal.
Man part 5 I love it
I'm looking forward to getting some of your Silver soon.
ya got us drooling for the melt!!!
