Instead of using a premixed aqua regia, you could have controlled the amount of Nitric and not had to denox anything. A bit of salt would have dropped any other base metals and you'd filter then, twice through the same filter. All you'd have left is liquid gold, and dropped with powdered smb. Wash off with hydrochloric, then water trading off
i was thinking it's better to use dmg with cold water for more fast precipitation ? are you agree with me ? and seconde question what did you use to precipitate gold if pgm's are presente fe2so4 or other ? thank you
You don't seem to understand me. I'm talking about melting gold chloride into a shiny, 24-karat solid metal The problem is that gold chloride evaporates It leaves a brownish tint on the immediate edges. Note that I was only adding with the borax Is there an ideal way so that the gold chloride does not evaporate during smelting?
Thank you very much for this information, please what are the smelting materials, I have a problem with gold smelting, as it stains all the edges of the melting pot and evaporates What is the problem .
Sir, some time I add sodium sulfite, gold already precipitate then I drain and add water to wash it then gold re dissolve, and some time add sodium sulfite gold not precipitate the colour chang to dark-orang and then aqua regia very cool and gold not precipitate. Do you know the reason?
You used too much nitric acid. Warm up the solution then add sulfamic acid to DeNOx the solution then add sodium metabisulfite, after the gold has dropped remove it from the solution and boil it in distilled water
Hello sir . I have a question can you help me ! I'm refning gold 23k include ( 96% au, 4% ag) . I'm precipitate by smb and washing by hcl in 10minutes but my result is 999.5 . Do you have any advice for me to achieve 999.9 ? Looking forward to your reply ! Thank you and have a nice day !
After the smb precipitation and washing, redissolve the gold and use oxalic acid or sodium nitrite to precipitate it again (this should eliminate any PGMs if present)

Thanks for the tip
Very nice tip bro. Thanks 👌👌
Thats great thanks man ,can you tell me which salt
with salt u mean sodium hydrogen sulfate?
Excellent video thank you!!! Happy new year!!! Nice to see creators working together
Very nice Owltech always a pleasure watching your vids 👌❤
Glad you like them!
Go, go, go! (and make more videos... great stuff!)
Thanks! Will do!
Great to see! Happy new year
Thank you! Cheers!
Great way to start my day, gold and coffee. Good to see you my friend!

Hi! I dont find the same open fire cuppeling tray furnace and melting furnace but do you know product that works the same as yours that i can find?
Прекрасная работа.
С меня лайк.
Успехов в дальнейшей работе
Спасибо большое!
It is not good idea to increase temperature of precipitated by SMB solution because gold may dissolve back to the solution
Yes if you haven’t removed completely the oxidiser…. I learned that the hard way
i was thinking it's better to use dmg with cold water for more fast precipitation ? are you agree with me ? and seconde question what did you use to precipitate gold if pgm's are presente fe2so4 or other ? thank you
I dissolve DMG in NaOH solution, as for the PGMs I use either oxalic acid or sodium nitrite
Parabéns 👏👏👏👏👏💎🇧🇷
Excelente..
I like the 999 Dušan mug... 😀 The white gold in the end was interesting, 85% gold but white...

Reduce the gold chloride to gold metal and then melt it

What is the problem .
Melting or smelting? Gold metal or gold salt? I seriously doubt you can evaporate metallic gold with oxy propane torch
Text on screen is much better than the robot voice. I had to mute it. Great video tho

that clean gold sponge will dissolve in boiling HCl easily
Not in HCl alone
If there was any of the PMG in the solution,, what is used to precipitate gold only?
Depends if you don’t have base metals you can use oxalic acid, sodium nitrite or hydrochinon
@@OwlTech333 base metals are easy somehow to remove later,, PMG is a headache!! Thank you, man

You should go check out Sreetip's videos. He has a lot of good tips that might be useful.
I have already
I wish everyone who melts gold with an oxy/acetylene or oxy/propane torch would stop using a carburizing flame & use a neutral flame.
Muy bueno 👍,, 🇺🇾
