In this video, I refine all the gold I've managed to collect throughout the year. Taking my dirty gold powder full of impurities and refining it to 24 karat gold.
I see there at the end your solution went from 150 ml to over 400 ml... I assume you diluted with more water and raised the PH to around 4-5ph with soda ash? Since I see there was no reaction when you dropped the SMB in..
Small amounts of silver chloride can dissolve in a concentrated solution. Silver chloride is insoluble in water. Adding tap water helps to cool the solution and precipitate these small amounts of silver chloride, which then get filtered. The solution also increases every time I filter it due to ensuring all the pregnant solution is washed from the sides of the beakers.
Sulfamic acid is used to remove any lead (Pb) present in the solution. The sulphamic acid reacts with the excess nitric acid to produce sulphuric acid. The sulphuric acid converts the lead chloride to lead sulphate, which is insoluble and precipitates from the solution. This can then be removed with filtering
Thanks for watching. Unfortunately, as my mother used to say to me, I have a face for radio and a voice for photographs. I use the ai voice to make sure the video is understandable to everyone as I have quite a strong regional accent
Not much but it's a waste of acid, evaporating and re hydrating is another way to rid the solution of nitric acid excess. So I wouldn't imagine that much of a loss
I love your explanation on Ferrous Sulfate vs SMB and why. Good recovery, I have a bunch of e scrap to play with.
Glad you enjoyed the video. Thanks for watching 👍
Well done !
Thanks mate 👍
Nice explanation
Thank you. And thanks for watching 👍
I love Ur teaching Sir, but in my locality we do not have this chemicals

The solution was diluted, yes.
@@3-2preciousmetalrecycling hmm but Why? I see some people do that and I see some don't.

@3-2preciousmetalrecycling Appreciate the responses brother. I've got a batch right now cooking in some acid.
Awesome. Hopefully you get a good amount 👍
Why use sulfamic acid?.explane pls.

Nice video. Would love it if it was your voice though.

Why are lids always placed on container during reactions?
Watch glass prevents large evaporation and it prevents anything unexpected from falling into the solution
With evaporation can you have a loss of gold?

Please can someone help me with a better offer, I have 100pcs of scrap phone panels.
come on man.. quit using these ai voices... wth.. lol
atleast you got the facts correct though about ferrous sulfate and smb.. right on
Thanks for watching 👍
