Greetings,
I recently processed some materials (around 250 grams)
I have been accumulating them for months.
They are similar to the MLCC but they are the black ones and the one's with the numbers usually (100) or something rather. I incinerated them with a portable butane torch, then crushed them into fine powder.
I gave the material a bath of nitric to see if there are any silver available. Alas silver was present after adding household cooking salt diluted in warm water. (not a lot of silver perhaps close to half a gram if that).
Next I placed the materials into AR with nitric added in increments. I did a Stannous check and gold was present and was precipitated with SMB again yield is minimal.
After filtering I checked again with a Stannous and to my surprise the test result was not what I was expecting.
I expected NO reaction yet the test gave a very dark brown result but never turning black. When I read Hoke's book she said that platinum gives this result with a Stannous test? Did I misinterpret? Could there be platinum in the solution? DMG is way too expensive and out of reach for my budget. Are there alternative methods for dropping Pt?
Please help....
Cheers,
Johno
