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 .
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.
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 ???
@@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?
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?
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
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?
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.
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?
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?
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,
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?
Hi there!!! I need help. I want to refine gold out of 500 gramms of copper, Bronze, silver and steel. Can I refine it by melting it down and pouring it inside of this pyramidical mold?
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?
Please advise: Are you able to use the cupellation process with gold filled jewelry? would I need to melt the GF jewelry first to make a button then add lead to start the process? I just need to know the process please.
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.
Great technical skills! The question I have is in terms of gasses that may be coming off the process into the air. Is there any danger to you from anything that is going into the air from the melting process?
When lead is melted, fine, poisonous particles are formed, that can travel long distances and remain in the environment for a very long time; Lead vapour may easily be inhaled, and transported through the bloodstream to the brain and other organs; Lead particles can settle on the soil, clothing, skin and hair, toys
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
Great video and exactly what I need. Is a stainless steel bowl required or can other types of bowls be used? The final piece of gold is what “k” weight? Thanks so much.
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
Is this doable with scrap jewelry to purify the gold and silver? I know sterling is rather difficult to remelt and recycle, so if I could purify it to fine and then re-alloy, that would work better for me
Just curious what problems you have ran into melting sterling. It melts and pours like pure silver for me. I clean it up with a graphite rod but that's it. Never had an issue.
So what you produce out of the alloy was pure gold or how close to pure gold do you get doing that process of melting out base metals with lead oxidation
fascinating experiment. Maybe if you used a known karat of gold such as 18k the weight before and after may show how close you get to fine gold without spectral analysis. Twp questions I have. What is the dish made of that you put the portland cement in and what is your ratio of gold to lead .
This is the most expert in action.
So just use cement barrier gold in then lead on top, melt to refine it. This video has been helpful, Thank You!
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?

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.

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.

Is it really that easy?
Do you recover the lead from the cement afterwards? How do you safely dispose of the lead tainted cement?
How long was your first melt before the lead disappeared?
Thanks
So what’s the ratios to gold weight to how much lead to add
How long did it take to refine your gold button
How long does your furnace/kiln have to run to cupel gold/silver?
Just 1 question how long does it take to do? I’m wondering if I can just use a can torch.
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 ???
Your capacity to simplify what others make complex amazes me. That was an awesome demonstration. Thank you.
Thank you so much! 😀
@@mbmmllc hello, I appreciate you very much for sharing your knowledge, thank you.

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.
Very interesting...
Is there a specific ratio to the Lead and "gold" button prior to refining???
Will it remove copper?
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
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
the final buttons are a mix of gold and silver? what karat are the buttons?
Will brass be removed as well?
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?
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.
Is Portland Cement For General Construction Applicable For That Process
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
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!
hi Master, what kind of Portland cement do you use for gold cupellation? type 1-2-3-4-5?
Thanks Jason great vid, it would be interesting to know what purity you ended up with?
Can this same process be used for silver?
Would this work with a silver/tin alloy? What determines how much lead to use? Thanks!
I’m wondering how long the process took just so I could have adequate fuel for the torch fire.
Now is there still silver in that or is that pure gold
I'm just curious
@@JBBURG666 yes
Is that Porland cement color green? gray? Can you use white Portland cement?
Do you know the purity to which you got them with this method?
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?
Can you use rocks with gold deposit to retreive gold in your way you just showed us ?
I followed your instructions but somehow the gold is gone and instead got a red glass substance how can I recover the gold?
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 use that stainless steel mixing bowl in the furnace? TY
Do you wear gas mask or a filtration mask when you heat the lead?
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

This works with silver too ?
Hello friend
Is lead have silver or silver oxided with lead and in finaly stay gold in this way
Does it have to be Portland cement or will any cement work
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,
You would be left with a lot more base metal in your button
Can soda carbonate be used same way
Hi Jason can you do that with a 3 kilo bar or not
work this also in an melting furnance ?
if i put the cement in the Graphit crucible ?
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
If you have gold and silver melted together how would you separate those 2 metals?
Aqua regia
How long do you have the flame on the cupel?
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?
What did you use to remove the base metal from the gold and one more question is it dangerous or not? Reply plz
Would this same method work on 925 silver?
Would this work with those impure scrap gold bars you can find on ebay
Yep
@@mbmmllc Nice 🙂
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.
Hi there!!! I need help. I want to refine gold out of 500 gramms of copper, Bronze, silver and steel. Can I refine it by melting it down and pouring it inside of this pyramidical mold?
How do you know how much lead to use?
Will copper be removed as well
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
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?
Please advise: Are you able to use the cupellation process with gold filled jewelry? would I need to melt the GF jewelry first to make a button then add lead to start the process? I just need to know the process please.
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.
How does putting letter with the top of your gold remove the base metals and the lead
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
What temperature do I need to keep the gold for it to do it’s thing? How long on average does it take? Great video!
If i use this way with sand have ore gold . Is it work well ?
Whats the big thing your buring in , where can i buy one
Does the magnesium cupel work better than Portland cement, if so how much better?
How is this any different to boiling several tons of acids? Seems way, way easier.
Great technical skills! The question I have is in terms of gasses that may be coming off the process into the air. Is there any danger to you from anything that is going into the air from the melting process?

Definitely do it outside you do not want to breathe heating lead
Did you use cement as a cupel?
Hello I have tried reaching out to you guys to ask a few questions regarding this process! Mainly can I use mortar as a substitute?
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
Does it have to be Portland cement can't use anything else
How do you allow for o2 to enter this wool structure? + how long does it take? great videos though!!

Just curious what problems you have ran into melting sterling. It melts and pours like pure silver for me. I clean it up with a graphite rod but that's it. Never had an issue.
If I had a 57 gram piece of gold scrap how much lead would I use to cupelle my gold??

Yes, works good on Ag
Does it have to be portland cement
So what you produce out of the alloy was pure gold or how close to pure gold do you get doing that process of melting out base metals with lead oxidation
can you reuse the portland cement
How do you vent off the toxic lead gassing.
Most important take away from this video.
Portland is a great alternative to bone ash crucibles
Thanks so much. Great tutorial
Great! Thanks!

The dish is a stainless steel bowl from goodwill and the ratio of gold to lead should probably be about 1:1

How can you make that work when it’s Jewelry or computer connections
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 would you get the lead out of the cupel
Hey cool video! What is the formula your using for how muck lead you use for how much metal to be refined?
And what is your opinion of when you use a graphite crucible compared to a silica?
Will this work with pieces of recovery gold from electronics? What's the average recovery rate from an authentic seller?
What was it that you used as your cupel? Perlite cement?
What grade is this? .995? .9999?
