Hello Fellas,
I have read a couple of topic but I can't find result like that.
I have nitric treatment stock pot. It is full of saturated with copper.
I read cement tips to make true the process.
Then I try belows,
A- PH=0 saturated with copper. There is black powder. Solution dark green.
B- PH=2 with tap water. saturated copper. There is a little bit black powder. Solution dark green. yellowish brown dust.
C-PH= 2 with urea. saturated copper. Ther is a little bit black powder. Solution dark green. yellowish brown dust.
Dried dust remain. Just I have this photo sorry. I melt yesterday a little bit.
I suspected that this yellowish-brown dust would be copper then I filtered then melted. Color is like gray metal color. I guess it is a little bit shiny from silver. What is your comment, what that it is?
I have no DMG. It is very expensive here.
