Easy DIY Gold & Silver Refining Process At Home, No Acids. Remove Base Metals By Cupelling MBMM
ฝัง
- เผยแพร่เมื่อ 13 ม.ค. 2020
- Gold & silver refining using the cupelling process for removing base metals (copper, lead, iron, antimony, zinc, etc) from our smelted gold buttons. This process works on silver as well as platinum, palladium, and other precious metals, too. This is an ancient process that has been used since the bronze age for removing base metals from precious metals. It is inexpensive, low tech, low skill and works very well for getting refined gold and sliver with very little contamination. Using only lead, portland cement, and a torch the base metals are heated, oxidized, and removed from the precious metals by the cupel. It is a great way to take your smelted gold, silver, precious metal buttons and increase the purity of the precious metals with very little work or effort.

Nice. Gotta love the gold 😊
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.
So just use cement barrier gold in then lead on top, melt to refine it. This video has been helpful, Thank You!
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!"
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.
I just love your videos! Thank you for making them
Qqq
Thanks for the information that you have provided Jason 🙂 I have checked out some of your previous posts & the technical details of process 👌 🙂
Thank you for your comment and for watching our videos!
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 .
Thanks for watching! Make sure to watch out for our next video!
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
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
Super vidéo. Mais permettez-moi de parler de quelque chose d'important, je vois que beaucoup de jeunes et moins jeunes font des erreurs que je pense qu'ils ne devraient pas faire. Je crois que tout le monde, jeune ou vieux, devrait avoir un plan d'investissement qui fera passer son rendement financier de trois chiffres à six chiffres. L'investissement peut être votre plan de retraite ou votre plan futur, selon ce que vous voulez, mais le plus important est que vous ayez un investissement qui soit rentable.

Oh very cool I’m going to try it! 👍
Macgyver gold channel, love your take on refining!
Thank you for your comment and for watching our videos!
Very interesting. Thank you!
Awesome! Very informative! Just what I needed to know, thank you very much!
Amazing information, thanks for sharing.
Great video, Jason. Thanks for putting it together.
Great! Thanks!
Wow..! Great video and thanks for sharing...Congrats bro ! Best regard from Indonesia
Thank you for your comment and for watching our videos!
Well done mate!
Thank you OwlTech for your comment and for watching our videos!
Thanks Jason. Very informative... your channel is awesome. Subbed.
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.
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 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?
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
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
Thank you for your comment and for watching our videos!
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.
Can u use lead sinkers? Or is roofers lead specific
Is the Portland cement sand free?
Truly enjoyed the smelting procedure...
Thank you for your comment and for watching our videos!
Do you recover the lead from the cement afterwards? How do you safely dispose of the lead tainted cement?
Thanks Jason great vid, it would be interesting to know what purity you ended up with?
hi Master, what kind of Portland cement do you use for gold cupellation? type 1-2-3-4-5?
How long was your first melt before the lead disappeared?
Thanks
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?
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.
Hi Jeff. Thanks for the suggestions! We will try and keep the gold coming!!
2 of my favorite TH-cam 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?
very good work
Thank you for your comment and for watching our videos!
Do you use less or more lead depending on the weight/purity of the gold? Say i have a gram of 10k what would be the lead recipe? And was there a certain attachment on the propane tank to have a "furnace effect"
the final buttons are a mix of gold and silver? what karat are the buttons?
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.
New here. Very cool. Thanks for sharing
Thank you for your comment and for watching our videos!
Kerja yang bagus, terima kasih.👍
Thank you for your comment and for watching our videos!
Nice love from india
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.
Does the magnesium cupel work better than Portland cement, if so how much better?
work this also in an melting furnance ?
if i put the cement in the Graphit crucible ?
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!
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.
i like everything the way you did this! very instructive video! I'm just wondering what is the purity of gold in the end as a percentage? thanks in advance and keep up the videos!
Most important take away from this video.
Portland is a great alternative to bone ash crucibles
Thanks so much. Great tutorial
Great! Thanks!
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?
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 ???
Thank you for sharing 💪💪😎
Thank you for your comment and for watching our videos!
@@mbmmllc 💪💪💪💪
I hate working with harmful chemicals thanks so much for this! 😫🙏🏽🙏🏽👍🏾
Awesome!!! will this work with placer gold?
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!
Do you use that stainless steel mixing bowl in the furnace? TY
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.
I just watched that gold lead melt! Piece of cake
Thanks for watching! Make sure to watch out for our next video!
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?
Just 1 question how long does it take to do? I’m wondering if I can just use a can torch.
So what’s the ratios to gold weight to how much lead to add
Hey man Out of curiosity What equipment do you use I'm asking because I'm thinking very strongly about doing what you're doing And the reason why because I can get some pretty good deals on some go bars That has mixed metal in thim
Is that Porland cement color green? gray? Can you use white Portland cement?
Great video. Will this process work with raw silver ore and tailings?
Nice
Will this work with pieces of recovery gold from electronics? What's the average recovery rate from an authentic seller?
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
Would a cupel work to refine a piece of 14k gold jewelry ?
💥💯 Totally enjoyed the show man 👍💥 ! So the lead takes care of the silver to ? Very interesting stuff , Thanks for sharing 😊 ✌️🇺🇸
What was it that you used as your cupel? Perlite cement?
How do you allow for o2 to enter this wool structure? + how long does it take? great videos though!!
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
Does it have to be Portland cement or will any cement work
Where do you get that furnace set up and where do you sell your raw gold at?
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?
❤❤شكرا لك. ❤❤
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
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?
Hi Jason can you do that with a 3 kilo bar or not
How long does your furnace/kiln have to run to cupel gold/silver?
How does putting letter with the top of your gold remove the base metals and the lead
Is this method will work to remove copper from 14k gold?
If i use this way with sand have ore gold . Is it work well ?
How long did the whole process take to complete the first bead .
Can this same process be used for silver?
Would this same method work on 925 silver?
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?
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
How long did it take to refine your gold button
Where do i find a diamond shaped pour pot like u use
I have 13 oz of gold filled pocket watches that I would like refined, would this process work for that? 1/20 gold 19/20 copper and other base metals ? Thanks Brian in Highlands Ranch Colorado!
Can you use rocks with gold deposit to retreive gold in your way you just showed us ?
Hello friend
Is lead have silver or silver oxided with lead and in finaly stay gold in this way
So it makes the gold more pure giving it higher karats?
What did you use to remove the base metal from the gold and one more question is it dangerous or not? Reply plz
How long do you have the flame on the cupel?
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 ?????
If I had a 57 gram piece of gold scrap how much lead would I use to cupelle my gold??
How can you make that work when it’s Jewelry or computer connections
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?
Great video Jason! I was hoping I could ask a rookie question if that's ok?! I'm having a hard time getting all the micro fine gold I'm finding and I was wondering if the blast furnace stage - where you create the Lye/Borax/Silica flux will help me remove all the fine sands. Does this just turn to glass in the slag? This will save me hours of panning gold dust haha! Thanks for all the amazing content man - you're teaching me to mine!! :)
It is better to invest now. You will never be younger than you are today and there will never be a perfect time to invest. Due to compounding, which Einstein called the 8th wonder of the world, you can get rich slowly from investing if you do it from a young enough age.
Does it have to be Portland cement can't use anything else
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
