G is right, the little bit of gold got precipitated in your second picture above, where the 500g of smb was added.
I know the producer told you that he used no less than .6g/kg......but, this is the precious metal game, and to take a seller at their word, is the fastest way to get played
Hi,
Before the dissolution in AR, i had 98 gram of solid in the filter.
Afrer dissolution in AR , I had only 41 grams of solid stuff.
This is the picture of solid stuff... just same plastic, i think.
