well planned out, and very nice yummy gold, thanks for the video, i was just also wondering why don't you use a conical crucible first to get the slat uptop and the good gold at the bottom of the V
copper is one of the metals used to create karat gold since pure gold is too soft. nickle and silver are also used. My volume is not large enough, I only get paid for the gold and some of the silver. If my volume is 20 times what I buy a week, I can get paid for all other metals in the bar that I melted.
Hello Pei Wu. I have to install equipment similar to the one in the video. With a Pillar induction system. Do you have connection plans for the equipment?
if you want to get pure gold you need to refine it it is a complex proses and is rather dangrus using acids to disolve the metales then outher cemacales to seprate it
@FreedomForYouAndMe The pour borax in the crucible and all the impurities stick to it. Since gold is heavy and all the non metals, stones or diamonds stick to borax and floats to the top. During the final 2 minutes of the melt a glass tube is inserted into the crucible to get a sample to test the purity or percentage of gold by a x-ray spectrometer. Then the molten gold is poured into a mold to let it cool and then dumped in the sink to separate the borax which black now and hard as a rock.
So being a somewhat metallurist myself but mainly strategic metals like 7000 series aluminum and titanium and of course Steel I see you are skimming the slag or bort off the top using BORAX...how hard to take to 22k or 24k? Is that a trade secret by Mid western and other refineries? My buddy used to send to Eastern Smelting Lynwood, Ma.
Mr.Pei Wu; why did you start to "pick" at the gold after you had already scooped 2 scoops into furnace an do you have really nice jewellery and are you a jeweler? thank you in advance for any time and your consideration. Art
The margin is high if you buy from the public. I buy only from dealers who buy from the public and make a a good percentage. I deal directly with the refiners who take a few tenth of a percent off the spot gold price. I then take a few tenth off from the dealers I buy from. I can't take more because the competition is very cutthroat.
have you ever tried fractional smelting? This is where you have alloy or mixed metals and start with the lowest melting point of the metals once the melt out you pour the raise the temp to the next lowest and keep repeating. Or does your style of inductive furnace not allow?
It doesn't really matter since I only get paid for gold and silver. Once the batch is melted in the crucible, a glass in dipped into the crucible to get a sample. Then the sample is first analyzed by computer and I get paid 90%. Then a piece of the sample is sent to fire assay which is more accurate determination of percentage of gold and silver. I then get paid the rest. As for other metals, I don't bring enough scrap gold. When business was good last year, I used to melt at least 10 to 15 kilos of scrap gold a week. I need at least 5 times more in order to deal with the big refinery in Chicago. They would pay more on the gold and also pay me for every metal. I also use another method. It's called Aqua Regia. I only use this method when I get jewelry pieces with diamonds still on them. Some diamonds may crack when the furnace is used. Removing small 1 point diamonds by hand from jewelry pieces is a pain in the neck and can take very long time. So I save the pieces with diamond until I have a lot and use aqua regia. It uses acid and removes gold only. It takes a few hours and when the process is finished I get diamonds, stuff that is not gold and gold mud. The we torch the mud and it become pure gold nugget.
Thenghee Teh I take out the pieces with diamonds and save it until I have enough to processed with acid. All other piece with CZ, onyx or other non precious material are removed with either pliers or a hammer.
Pei Wu,...removing non precious stones from jewelry pieces is a tedious thing to do. My idea is to clear all the stones that stuck around the melted bar with hammer, then brush it with running water....but just not too sure about it. What do you think?
ganimed1976 he probably doesn't have the ability to easily refine it into 99.9% bullion. Easier to melt it down then sell it to a refinery to have it refined then stamped into pure gold bars to be sold to banks and the like.
Some of the gold probably do stick to the crucible. I asked them to get as much out as possible. When the crucibles are no usable, they process them to get all the gold out of them and keep as profit.
Your buying from the wrong people. The pawn shop gold market is like stealing from the public. It is a quick way for thieves to dump off stolen goods. the pawnshops then send it to the refiner as quickly as possible because they know it is stolen! Local pawnshops here pay $200-300 an ounce. That is a crime in itself. the whole market is a sham.
MrEternalpk Thank you I knew this I used to have friend in 80s and 90s did what you do and I want to as well but I want to go all the way big time let me just say THE ATOCHA is done the LA MARGARITA is done by FISHER and well I want LA CAPITANA yeah the mother load! Imagine tons of 14K and 18K?
Why make a video of how to melt scrap jewelry if you’re not going to talk about what you’re doing? What was that round bar you were cutting up? What did it do?
It's an electric furnace I have no idea how it works. There is a big unit next to the crucible and creates this very high pitch sound when its running.
how about some eye protection. borax it self also holds golds because you do not have any other flux to loosen it up (fluorspar). don't leave out that you make thousands off your slag at the end of the year. what is this ammature hour? lol
+Pei Wu I want to make 14k gold out of my pure 24k gold ... How much would that cost me ? And how much would 500 gram of pure gold yield in 14k gold ??
The profit margin is very low because competition is fierce. For every ten thousand I spend, I only make around $70 to $80. That var was 90 ounces or pure gold so I probably spent $120,000 and probably made 8 or 9 hundred dollars, That was over a year ago, now the profit margin is even lower since more and more people are buying scrap gold
Your so full of crap.The margins on buying scrap gold are huge. You basically pay thieves to go steal from people and pay them next to nothing for the stolen gold. If you are paying more than 25% of the value, you are not up to standards.
God now everyone knows what my kitchen looks like . Thanks dad !

Very interesting. What was the piece you set aside when you loaded the crucible? Something worth more than it's melt?
@FreedomForYouAndMe The pour borax in the crucible and all the impurities stick to it. Since gold is heavy and all the non metals, stones or diamonds stick to borax and floats to the top.

Very interesting process. I didn't realize there was so much copper in gold jewelry. Is it used to harden the gold?
no es oro puro 24k ? el oro 24k no puede refinarse solo o necesita siempre de cobre?
What purity is it...and do you still have use of your fingers and eyes? Thanks for the vid.
Hi..did you know how get the pure gold from copper & metal mixture ingot bar!
what equipment are you using to melt who makes it ??
wonder what percentage of that is rap stars grills
Not many people can say "I think I'll go make some more gold bars today." and actually do it.
Real slick mixing about five ounces of silver in I saw you Tisk tisk
So being a somewhat metallurist myself but mainly strategic metals like 7000 series aluminum and titanium and of course Steel I see you are skimming the slag or bort off the top using BORAX...how hard to take to 22k or 24k? Is that a trade secret by Mid western and other refineries? My buddy used to send to Eastern Smelting Lynwood, Ma.
el oro 24k solo no se puede fundir? siempre necesita de cobre?
i wonder how many family heirloom jewlery worth more than its scrap value gets sold to those cash for gold places...
Eye protection. Two eyes are a good thing.

rat tot.nhung biet nua thiet bi nay o dfau?
Pei Wu where is your jewelry store located ? I am in Philadelphia and i would like to dialogue with you about connections in the gold business.
Dont know much about this profession but was surprised at seeing no eye protection or gloves most of the time
My God... his water bill must be sky high... he just left it running while he went back to the gold melter thingy!! :)

Pei Wu I have mainly worked with silver from electronics (computers). Saving the surface mount capacitors for a platinum/palladium run.
Pei Wu, it would be interesting to learn how you handled jewelry pieces with cheap stones on them in the process. Can you elaborate, please?
Thenghee Teh I take out the pieces with diamonds and save it until I have enough to processed with acid. All other piece with CZ, onyx or other non precious material are removed with either pliers or a hammer.

ICBS banking/holdings /STOCKS EXCHANGE
I don't understand why you are making a 14k bullion out of 14k scrap gold? Is it because a bullion is easier to store?
You can sell it for more
ganimed1976 he probably doesn't have the ability to easily refine it into 99.9% bullion. Easier to melt it down then sell it to a refinery to have it refined then stamped into pure gold bars to be sold to banks and the like.
After melting all the gold into a bullion, I sell it to the melter as is. Refining it into .999% gold is really expensive.
Don't forget, pure gold is 24 carats so 9 carat gold is only 37.5% gold - there's a whole lot of cheaper metal in there as well.
Doesn't some of the gold stick in the porous parts of the crucible? That would waste quite a bit over time.. Or, am I mistaken?
Some of the gold probably do stick to the crucible. I asked them to get as much out as possible. When the crucibles are no usable, they process them to get all the gold out of them and keep as profit.
No, the only way fast is to hammer it. The gold will not chip because it not pure and is pretty hard.
a CROWN FOR A KING
There a way to remove the solidified flux/impurity resin, without chipping away/scratching the gold?
Her fella, they use acids for that.
Your buying from the wrong people. The pawn shop gold market is like stealing from the public. It is a quick way for thieves to dump off stolen goods. the pawnshops then send it to the refiner as quickly as possible because they know it is stolen! Local pawnshops here pay $200-300 an ounce.

Rob The Plumber fucking dumb comment
I want to eat gold. I don't understand myself. I mean, whenever I see a gold it makes me want to eat it. I'm literally craving.
how do you separate the Bort metal from the Gold ? You gotta use Cyanide somewhere along the process right?
the royal mint purify it further
Yup I knew it have to use more than BORAX to purify it ie CYANIDE?
yes
MrEternalpk Thank you I knew this I used to have friend in 80s and 90s did what you do and I want to as well but I want to go all the way big time let me just say THE ATOCHA is done the LA MARGARITA is done by FISHER and well I want LA CAPITANA yeah the mother load! Imagine tons of 14K and 18K?
At 4:55 - 5:00, the melted metal comes out in a stick shape. How do you do that?
That looks very interesting.
He used a thin glass tube and dipped in the molten gold. Heat created a vacuum and the gold is sucked up.
Pei Wu Thank you!!!!
Nice Pile.
Why make a video of how to melt scrap jewelry if you’re not going to talk about what you’re doing? What was that round bar you were cutting up? What did it do?
Need to make aqua regia and let it dissolve, then precipitate it out with some SMB, your half way there !
So....do you have to separate out the 10k from the 14k or can you melt them together?
if u mnelt them together you will get something beetween them
yeah you can melt them becus the are same thing right? so basiclly its mixing different qualities :S nothing more nothing less :D
Chronosphere Steen Exacly
yey my school work payd off on youtube comments :D
its a shame that most of what people call gold and silver scraps are actuly useable jewelry that people will pay way more for then melt
who know how many degree celcui in the melting furnace?
So long as it exceeds the melting point of gold, it should be fine. The melting point of gold is 1,064 degrees Celsius,
It's an electric furnace I have no idea how it works. There is a big unit next to the crucible and creates this very high pitch sound when its running.
Only 58.4% gold. A little over half of the bars weight!
can i have it?
how about some eye protection. borax it self also holds golds because you do not have any other flux to loosen it up (fluorspar). don't leave out that you make thousands off your slag at the end of the year. what is this ammature hour? lol
good
you dropped something on floor......
Merci
This is not even worth it then.
no eye protection - reckless foolishness
where did u buy this gold ??
+Kalash FDP I work in a refinery. People bring the gold to me
+Pei Wu ha ok and is it a hard job ??
+Kalash FDP Not really. Takes time to learn how to use acid to test the purity of jewelry.
+Pei Wu I want to make 14k gold out of my pure 24k gold ... How much would that cost me ? And how much would 500 gram of pure gold yield in 14k gold ??
+Jose Muñiz you'll have to find a jeweler to make it for you. with 500 grams of 24k, divide it by .585 you'll get 854.7 grams of 14k
I do make money since I buy a lot. I make more money buying than selling gold at my jewelry store.
MY MARKETS are belonging to DOLLARS&GOLD

Gold is not scrap!
Okk
Dare you to touch it.
I buy gold for 100 a ounce from old people
kalzx you must be very proud of yourself.
The profit margin is very low because competition is fierce. For every ten thousand I spend, I only make around $70 to $80. That var was 90 ounces or pure gold so I probably spent $120,000 and probably made 8 or 9 hundred dollars, That was over a year ago, now the profit margin is even lower since more and more people are buying scrap gold
this man simply does it right, hes påooring the gold first into the holder then into the marchine.. no cheating in this place :D i love it
Just metal )
at 1:00 wtf y wouldnt you go through it all before? you could of gotten hurt. i guess this is the idgaf way
@FreedomForYouAndMe It doesn't cost me anything since I sell the gold bar to them. If I just wanted to melt and keep the bar, it would cost me $50.
Ma e oro
Your so full of crap.The margins on buying scrap gold are huge. You basically pay thieves to go steal from people and pay them next to nothing for the stolen gold. If you are paying more than 25% of the value, you are not up to standards.
I call bull crap on your comment. Show me the idiot who risks $120K to make $900 and I will show you a guy I want to sell things to on a daily basis !
you're gonna be deaf!!
bzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
i wont to work there !!!!!
