Hello everyone
During work one patch was unusual
After pretreatment and AR dissolving when adding SMB the whole patch turned to white ppt
I filtered it and separated the precipitate.
It looks like fiber material
By searching it can't be metastannic or palladium ( i think)
Any suggestions about it
It is in
first container in the video

No need for videos.
Picture with description is way better.
What was the material dissolved?
Slag from gold-laden carbon
Pretreatment with nitric acid
By the way they ashed the carbon before smelting
Same stuff as before.
It is impossible to say what it is without testing.
I'd guess some kind of insoluble Sulfite or complex thereof since it emerges with SMB.
Yes, but if it is unfilterable, how are you going to find your Gold in the mud?
No this is in last step with AR
Ok, you can cement on Copper with dirty AR.
Actually it probably is the best way to treat a dirty pregnant AR solution
