no, you can't separate gold from silver or silver from platinum or palladium using cupellation, what you can do is separation of noble from base metals
Did you say it would work with all kinds of breaker contacts? I have some that are silver tungsten carbide. I was told that the tungsten carbide had a melting point of 6,000F degrees. If it's true will you lose any silver heating it to that temperature and how would you get it that hot? Thanks
I know its an old video but hope you can advise me. I use lead cupellation to cupel e-waste alloy that most of it Copper, once I use oxidizing flame the copper oxidized very quickly, is it practical to just use reducing flame for hours to oxidize lead? Is cupellation using propane flame must be reducing flame? Thanks for your help
Usually contacts from relays, contactors, etc are Ag+Pd for hardness 1-5% Pd which tend to stay in Ag as is also noble but increase melting point of Ag...
Why you put soap on your hands when washing them? Water washes away the soap together with the oils it’s has dissolved. Think of the lead (lead oxide to be precise) as soap
Will do thanks 😊 I don’t know if you would know anything about this but I heard , I think it was in a reply on UA-cam. Anyway I read that the tungsten carbide contacts could be sold for reuse but I don’t recall the reply saying who would by them, I have a few pounds of them. That was a great video. Before I saw it I thought the only way I could purify silver was chemically “nitric acid”
would u like to do this same "thing" ( "procces" ) BUT WITH PLATINUM?...and in add in VERY less = TIME?....coz THAT is what i 've been making for DECADES....
Thanks for sharing ! I usually add 3 times the initial weight with lead ( Like inquartation ) This let me free time to do sth else while processing... Like trying to recover my first stock pot... Challenging a PH9 mixed solution... Wish me good luck on it ! :D Regards.
hi! thank you for the video! i know almost nothing about metallurgy except for what im learning at high school, so i wanted to ask, how long can you keep adding lead to purify the silver? is there a limit to doing that?
Do you think this would work for h90 and h30 capacitors? I have some luck melting them directly and getting the metals bit there is a mix of some 10 metals and I would like to purify a little better. Thank you and Happy Holidays and a great New Year.
Thanks so much for showing off the cupellation. I wonder if you process most of the larger silver contacts from circuit breakers and contactors using this method? And also, how much batch can be processed at once and whether propane-butane furnace can be used? I have a few kilograms of these contacts now and I am looking for the most efficient processing method. Thank you and I wish you much success.
@@OwlTech333 Thanks so much for the link. Is it possible to use Cupellation for all silver alloys that are used to make contactor contacts? Although, if tin, cadmium, nickel, etc .... is contained? Thank you very much, have a nice Christmas and keep up the great work.
какую минимальную температуру должен создавать факел пропана , чтоб окиси забирались цементом ?? , у меня при 400 - 500 по Цельсию все шлаки остались в купели
Dang man I have a 55 gal drum that is this material i am sure ....i have found big lead prills in the drum along with the crushed up material that turns to lead when i hit it with a tourch i can see the gild in it as i pull the flame away...
Cool video. However burning lead and making fumes ..for me just won't work... I just refined a kilo of silver and used nitric...thanks for the videos buddy😁
You don't get a lot of fumes. The lead forms lead oxide which slides down the bead and is absorbed by the cupel. With nitric acid, you generate a lot of nitric oxide fumes - also very toxic.
Да понять та можно😀вот в этом процесе смысла нет совсем.Как тигелёк использовать для выпариванья сплава после купиляции свинцом это да,вариант...что бы тигельки не покупать,хотя они дешовые.Это когда с рудами,шлихами мутят и свинец как купелятор и растворитель золота,серебро до 20% поглощает,не катит кароче если когда с щолочами и до 700 градусов.😀Я автора очень уважаю,люблю смотреть,но в этом смысла не вижу.Медь,никель,хром и прочее что есть лигирующие в сплаве будет и никак не очистит этот метод,хоть кислородом продувай сам сплав часами,медь останится.Да и чистить эти сплавы свинцовые жопа,долго и нудно,всё в солях его или упаривать до апупения как автор показал.
Alex 1975 "Медь,никель,хром и прочее что есть лигирующие в сплаве будет и никак не очистит этот метод,хоть кислородом продувай сам сплав часами,медь останится." Извините но ето просто не так (в етом ролике покозал) мед очистилась все полностю. @8:05 металл замерз из-за меди @8:24 Я добавил больше свинца, и процесс продолжался до тех пор, пока серебро не было полностью очищено. Просто когда медь там есть нужно добавлят на 20 раза болше свинца. (1гр. Cu /20 гр. Pb) На конце купеляции остаются только ДМ
@@OwlTech333 с чего он медь вытолкнит от туда?Другие окислятся на воздухе и то не факт при такой плавке.Да это древний как мир способ😀м музеях манеты и изделия,сплавы хрен знает что.Да я этим мутю плавлю 3 года балуюсь,если спициальные флюсы сыпать при купиляции золота может как то почистится от примесей...те что силитра или другое убирёт.Свинец и серебро почистить не думаю😀золото,медь,железо,спутники свинца и прочие всё в серебре с таким методом,полно проб читал из наших мест...от добычи руд.Лаврио,Халькидики..на 1 кг серика до 2 гр рыжика и прочено куча
Jessica Roper the idea of the video is to show the full cupellation process from start to finish, not how I recovered 3g of silver. The purity of the refined silver after cupellation is what matters
Would this process also separate silver from gold? The latter in "nobler" than silver but maybe it would take too long to oxidize the silver ?
no, you can't separate gold from silver or silver from platinum or palladium using cupellation, what you can do is separation of noble from base metals
Thank you for sharing this knowledge.
Very nice ❤ good job 👏
Thank you! 😊
Thanks for sharing...pls what is the Karat of the extracted gold? And pls what further way to purify it more?
this is silver
If I use this method with 18kt gold will it separate out the gold and other precious metals
Yes
So I’ll end up with pure gold and silver when finished with the process with anything less than pure gold
how do you know when it stops driving? How can you tell when it is driving, please explain

Its very difficult but it does work, and you don't have to heat it to 6000F
Can Cupellation be used to remove the copper from Sterling Silver??
Yes
if you miss the flash over and keep the burner on will ever it burn away silver ?
nope actually you need get it pass that flash to get it pure

Oxidising flame
Coll video! Can you do this process with platinum or Rhodium too by any chance?
platinum yes, not sure about rhodium
Usually contacts from relays, contactors, etc are Ag+Pd for hardness 1-5% Pd which tend to stay in Ag as is also noble but increase melting point of Ag...
Why do I feel like catalytic converters just became more interesting lmfao
Why is the lead added? It seems counterintuitive to add contaminants in order to refine the silver.
Why you put soap on your hands when washing them? Water washes away the soap together with the oils it’s has dissolved. Think of the lead (lead oxide to be precise) as soap

Hi whats your torch situation? It seems like I would kill my acetylene tank doing this. This takes quite a long time?
Wonder if you added an oxygen tank and a big rosebud and cranked the temp if you could speed the process?
if you had some sort of press and die you could probably just make actual cupels with the cement (or go online and get bone ash from a pottery store)
You can
Thank you very much for sharing you knowledge brother , your doing it quite well in you tube !🏆❤️
Sampath Guruge Thank you!
did not know you could use portland cement for that i use bone ash will give that a go next batch i do thanks for sharing

Hello, sir, what is the name of this soil, which you are taking in a steel container and melt the metal on it
Portland cement

@@OwlTech333 Hi! I was surfing for bone ashes cupel and end-up on your video. Is there a diference? TY
@@mysticworld1129 yes, Portland cement is much easier to come by, plus using it dry gives you a cupel in 30sec as shown in the video

no limit, to the amount of lead you can add, but there is limit to the amount of base metals( especially copper) it can remove from the silver

За какое время в среднем свинец испаряется или окисляется ? Спасибо большое за ответ заранее. На примере 11 грамов
Где-то 10-15 минут

i don't, the cupels are collected for lead recovery

You don't get a lot of fumes. The lead forms lead oxide which slides down the bead and is absorbed by the cupel.
With nitric acid, you generate a lot of nitric oxide fumes - also very toxic.
