Well done, Jason! In addition to Portland cement (calcium oxide) you could use ground glass or calcium phosphate (available as a fertilizer or bone meal) or crushed magnesite. The problem with using glass is that gold is soluble in molten glass just like lead oxide is. If you were to use bone meal fertilizer, you would first have to burn off all the left over organics like fat which smells bad and smokes a lot. If you used copper as the collector metal while processing the original gold button, you may find a lot of copper remains distributed throughout the final gold button (to be determined with a quick x-ray analyzer). Gold and copper form a pretty strong marriage if inadequate amounts of flux are used. I wish more video authors discussed gold ore processing options like you have done so people wouldn't expose themselves to mercury, vaporized lead, cyanide, nitric acid, and a bunch of related compounds that form during the processing. Again, I must say: "Well done, Jason!"
@@finiszealot5539 I defer to Jason concerning which flux mixture to use. He has done a wonderful series on his experiments with a variety of flux mixtures.
Looks like the Portland cement is the way to go , i bought bone ash , and made my own cupels , but it's too expensive , so that's a great alternative , although i have seen it used before ,but your demo has convinced me , thanks , great demo , cheers .
@@mbmmllc hello, I appreciate you very much for sharing your knowledge, thank you. I have 2 questions, Where do I buy a piece of roofers lead? Can any of the other precious metals absorbed by Portland cement or roofers lead be recovered without using acids or dangerous chemicals?
great vi Jason ....would use magnesite or Bone ash for the cupel.....better absorption . Litharge might be easier to use as well. Beautiful chunks of Shiney ...... keep up the great work my friend.
I agree with Allen. I learned to pan from Jeff's videos and watching Jason with his turn key pcb system video years ago got me switched from metal recycling to e waste. I really appreciate the knowledge that you have shared as well as your time it takes to make these videos.
Qouted = Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the late 19th century by Joseph Aspdin, and usually originates from limestone
Thanks so much. Had to dig threw 2 years worth of videos till someone explained what portland cement is. I've never heard of it until I watched this channel. Thank you.
Hi mate just wanted to ask you if you how a idea how much lead I will need to get the gold out of I think the bar weight is 5 kilo bar of mixed metals from gold pins and so on
there are 5 types of Portland cement in my country and I do not know which type is suitable for gold couplling. Please answer my questions. 1-2-3-4-5 ??? Which type do you think I should use ???
Do you know how much lead to use for the different carets or does it not matter? It looks like you used about 6x the weight of the gold... is that a good math on it or can it get more apecific?
What would happen if you only used 50gm of lead? Thanks for sharing this video. Interesting experiment. Wishing you and your team another great week. Cheers,
I was trying to cupel with a Magnesium cupel(or maybe bone ash) and tried few times and almost every single one cracked and droplets of litharge sip through the cupel. I had it sitting in the storage several years. I noticed whenever I put the cupel next to the burner pipe the cupel cracked instantaneously without any lead inside. Is it old cupel or I'm doing something wrong? Are they meant to be that fragile? Do they expire?
I'm not an expert but the lead can be leached from cupel waste effectively with acetic acid. There are some papers about this online but I've not found any definitive information on the exact process. I think theres a number of ways it could be done.
My question. At which point do yiu end the process. I was unclear on at the point when this is completely liquefied, as it cools, the gold and the impurities are seperated? And finally, is there a specific formula on how much of the pre-cut metal you need for x amount of Gold? You cut about 140 grams, how did you arrive at that figure?
Can u give me a detailed way of removing all metals from ic chips ,from incineration state to final gold in hand ,I'm kinda new at this want to learn I,have everything needed to do chem way or melting or cupellation method ,I am doing the electronics gold recovery
Are you sure that much lead is needed?. And are you sure there is no more lead left in the gold?. I make jewelry out of gold and silver. And i've been thinking of a way to purify ten fourteen k gold into some more shiny pure k gold ... Also, are you certain you're just losing base? Metals and not losing any gold?
How much lead did you use when u were refining the 15 gram ingot? Also i have another question. How come the lead and gold and not melting and mixing together? 🧐🧐 Can anyone explain?
hi ya jason you talk of using anhydrous borax what is the differ ance of that and just borax could i use regular borax please advise thank you in advance david j.
would it would be possible to use this process in separating gold from let's say old cell phones and electronic boards that have visibly good quality gold. Assuming everything is cut up into very small pieces. Could this process be used?
So it doesn't matter the furnace source as long as u have the right cupel material? So u can use bone ash cupels in a normal smelting furnace? Or do u need to have a certain furnace heat source?
How can i get training or where should i start looking for training on refining and recovery is there a class or how does a person get started doing this
lead oxidizes and in turn oxidizes the base metals with it and the lead and base metals gets sucked into the cement the lead drives off the impurities i believe some silver leaves and some remains which you can remelt gold button with sterling silver and inquart the gold by alloying it by 25 % of its weight and slowly pouring molten mixture into water then you can drive off the silver with hot nitric acid baths and recover .999 fine gold it looked pretty darn pure how he did it. gold it not very reactive to nitric acid it will dissolve a little but its a very small amount unless you just boil the shit out of it! there is a guy here on youtube goes by street tips who is really good with chem refining look up some of his videos, a+ in my book because he verbally describes the process very well! un like people who only put labels that end up behind things where you cant read and show horrible ways of disposal etc..
If we have a lot of other base metals like iron and copper and the lead content is quite high shall we use industrial propane burner instead of ancient wood and blower?
Can anyone tell me if this is possible doing this with a copper button that has gold in it ..... ???? Do you add led to it ? Will the Portland cement absorb the copper and led and leave behind the gold ?????
So just use cement barrier gold in then lead on top, melt to refine it. This video has been helpful, Thank You!
This is the most expert in action.

Thank you for your comment and for watching our videos!
So when doing it this way do you need flux ? And if so is it borax and baking soda ?
@@finiszealot5539 I defer to Jason concerning which flux mixture to use. He has done a wonderful series on his experiments with a variety of flux mixtures.
some XRF scans of these buttons before and after would be really informative.
Agreed, Have you seen the most recent video? It shows the results of the button afterwards
Blarg where is it
But it makes it easily obtainable with Portland no ordering or special stuff which is so nice.

As a person that used chemicals etc to extract and refine..... I’m going to change over to this process. Thanks for sharing and educating me
Your capacity to simplify what others make complex amazes me. That was an awesome demonstration. Thank you.
Thank you so much! 😀

Hi Jeff. Thanks for the suggestions! We will try and keep the gold coming!!
2 of my favorite RUclips guys. lol
you guys should hook up and do a video. Could help the rateings. would be fun to see too.
I agree with Allen. I learned to pan from Jeff's videos and watching Jason with his turn key pcb system video years ago got me switched from metal recycling to e waste. I really appreciate the knowledge that you have shared as well as your time it takes to make these videos.
Is it really that easy?
Great video! Question, is there a ratio of gold to lead to do this? Also, how long does it take for the lead to absorb into the concrete powder?

Can u use lead sinkers? Or is roofers lead specific
Is the Portland cement sand free?
Scrub that floor when done. And clean the lababo as well.
Do you recover the lead from the cement afterwards? How do you safely dispose of the lead tainted cement?
Macgyver gold channel, love your take on refining!
Thank you for your comment and for watching our videos!
Just 1 question how long does it take to do? I’m wondering if I can just use a can torch.
How long was your first melt before the lead disappeared?
Thanks
the final buttons are a mix of gold and silver? what karat are the buttons?
Hi mate just wanted to ask you if you how a idea how much lead I will need to get the gold out of I think the bar weight is 5 kilo bar of mixed metals from gold pins and so on
So what’s the ratios to gold weight to how much lead to add
thats just so amazing. i guess thats how most did it in the old days! well, if i ever need to refine gold, you can be sure i'm going to do it this way
How long does your furnace/kiln have to run to cupel gold/silver?
I would have liked to seen you shoot that gold with a spectral analysis gun and see what the readout is
Will do! Coming up on a new video!
Wow! Its incredible,its become shiny and beautiful gold.and also have improve the the grams.
Thank you for your comment and for watching our videos!
How long did it take to refine your gold button
Now is there still silver in that or is that pure gold
I'm just curious
@@JBBURG666 yes
Could you show how to "cement " gold onto copper in a furnace?
I would be so grateful.
P.s. thank you for uploading this video.
Thanks Jason great vid, it would be interesting to know what purity you ended up with?
this helps a lot...because i cant buy a lot of chemical to remove base metal of the gold...thanks...

You would be left with a lot more base metal in your button
Jason is there a way to extract the lead from the cupel after it is used to make the cement safe to dispose of.
Thanks for the help

does lead cupeling remove the silver and or copper from the gold
It would not remove silver, but the copper should also be absorbed by the cupel.
Most important take away from this video.
Portland is a great alternative to bone ash crucibles
Thanks so much. Great tutorial
Great! Thanks!
How long did the whole process take to complete the first bead .
Would this work with a silver/tin alloy? What determines how much lead to use? Thanks!
I just watched that gold lead melt! Piece of cake
Thanks for watching! Make sure to watch out for our next video!
Is Portland Cement For General Construction Applicable For That Process
Truly enjoyed the smelting procedure...
Thank you for your comment and for watching our videos!
Oh very cool I’m going to try it! 👍

Qqq
Very interesting...
Is there a specific ratio to the Lead and "gold" button prior to refining???
is any of the lead getting vaporized? and is their a way to recover the lead?
Yes and yes
@@speedonz do you know how to recover the lead or place i can get the info.
I'm not an expert but the lead can be leached from cupel waste effectively with acetic acid. There are some papers about this online but I've not found any definitive information on the exact process. I think theres a number of ways it could be done.
@@speedonz thanks for your help
About 99% of the lead is absorbed into the cupel. I will post a vid soon about how to recover the lead
Will it remove copper?
I’m wondering how long the process took just so I could have adequate fuel for the torch fire.
Would this same method work on 925 silver?
hi Master, what kind of Portland cement do you use for gold cupellation? type 1-2-3-4-5?
Wow..! Great video and thanks for sharing...Congrats bro ! Best regard from Indonesia
Thank you for your comment and for watching our videos!
Thanks Jason. Very informative... your channel is awesome. Subbed.
I hate working with harmful chemicals thanks so much for this! 😫🙏🏽🙏🏽👍🏾
Can you use rocks with gold deposit to retreive gold in your way you just showed us ?
can you try this in a bought cupel, with less lead. the ones they use for assaying.
Yes, I just bought some. More vids on the way
My question. At which point do yiu end the process. I was unclear on at the point when this is completely liquefied, as it cools, the gold and the impurities are seperated? And finally, is there a specific formula on how much of the pre-cut metal you need for x amount of Gold? You cut about 140 grams, how did you arrive at that figure?
work this also in an melting furnance ?
if i put the cement in the Graphit crucible ?
Can u give me a detailed way of removing all metals from ic chips ,from incineration state to final gold in hand ,I'm kinda new at this want to learn I,have everything needed to do chem way or melting or cupellation method ,I am doing the electronics gold recovery
💥💯 Totally enjoyed the show man 👍💥 ! So the lead takes care of the silver to ? Very interesting stuff , Thanks for sharing 😊 ✌️🇺🇸
Does the magnesium cupel work better than Portland cement, if so how much better?
Hi Jason can you do that with a 3 kilo bar or not
Is that Porland cement color green? gray? Can you use white Portland cement?
Would this work with those impure scrap gold bars you can find on ebay
Yep
@@mbmmllc Nice 🙂
Will brass be removed as well?
Does it have to be Portland cement can't use anything else
Are you sure that much lead is needed?. And are you sure there is no more lead left in the gold?. I make jewelry out of gold and silver. And i've been thinking of a way to purify ten fourteen k gold into some more shiny pure k gold
... Also, are you certain you're just losing base? Metals and not losing any gold?
Do you know the purity to which you got them with this method?
How is this any different to boiling several tons of acids? Seems way, way easier.
did you ever try to use bismuth instead of lead. I can't find the video you said you were going to make.
How much lead did you use when u were refining the 15 gram ingot? Also i have another question. How come the lead and gold and not melting and mixing together? 🧐🧐 Can anyone explain?
Well done mate!
Thank you OwlTech for your comment and for watching our videos!
Great video, Jason. Thanks for putting it together.
Great! Thanks!
Very interesting. Thank you!
hi ya jason you talk of using anhydrous borax what is the differ ance of that and just borax could i use regular borax please advise thank you in advance david j.
Thank you Jason for giving better ways of removing gold from mixed metals bars mate
Do you use that stainless steel mixing bowl in the furnace? TY
If you have gold and silver melted together how would you separate those 2 metals?
Aqua regia
So this has turned to pure 999. 24k gold?
Can soda carbonate be used same way
Will copper be removed as well
I followed your instructions but somehow the gold is gone and instead got a red glass substance how can I recover the gold?
Same here. Ever figure it out?
Would a cupel work to refine a piece of 14k gold jewelry ?
How do you know how much lead to use?
would it would be possible to use this process in separating gold from let's say old cell phones and electronic boards that have visibly good quality gold. Assuming everything is cut up into very small pieces. Could this process be used?
Your last comment was all you need to do was "send it off and get paid". Any recommendations on reputable & fair gold buyers? Thank You.
Amazing information, thanks for sharing.
So it doesn't matter the furnace source as long as u have the right cupel material? So u can use bone ash cupels in a normal smelting furnace? Or do u need to have a certain furnace heat source?
Hello Jason, Can you point a magnifying glass at a cuppelled gold button? It would be cool to see yours under a magnifying glass. Thanks and regards
How do you vent off the toxic lead gassing.
Whats the big thing your buring in , where can i buy one
How can i get training or where should i start looking for training on refining and recovery is there a class or how does a person get started doing this
Can this same process be used for silver?
Hello friend
Is lead have silver or silver oxided with lead and in finaly stay gold in this way
On the second round with the bigger nugget did you add the same 125-150g of lead or was it more having 3x the nugget then the 1st
I can't remember, but I think after doing it a few times now, only about 1:1 ratio is needed
What do you recommend as a way to dispose of the Portland cement?
I will make a video shortly showing a way to recover the lead from the cement. Thanks for watching
How does putting letter with the top of your gold remove the base metals and the lead

So it makes the gold more pure giving it higher karats?
Can u help with an equipment and materials I'll need to melt gold myself
Nice love from india
How would you get the lead out of the cupel
How can you make that work when it’s Jewelry or computer connections
