Gray powder

[Mac1969]

I have gray powder after I did my first recovery mixed with the gold flakes. How do I get rid of it. I used the vinegar salt peroxide method to recover the foils.

You need to give us more information such as what you were processing .
As a side question why did you use vinegar and salt instead of HCl ?

I didn’t have any HCL and was trying to do it it a little more disposal friendly. I was recovering from ram sticks and other cell phone parts.

Probably a mix of insoluble transition metal acetates and some silver chloride.

The moment it has dissolved metals it is no longer disposable friendly.
Actually salts from Vinegar may pose greater danger as Acetic acid is an organic acid.

This still makes a weak and often dirty hydrochloric acid. And is still not any easier to make "disposal safe".

Yggdrasil beat me to it, but...
