Pt,Pd,Rh ?

Hello fellow recyclers, have been member for some time and learned a lot.
Its now time for me to contribute, i have been asking to join spoonfeed group at FB regardings organs.
With no answer, and why should they if i dont bring at least something to the table.

Please get your Chemical signs correct, I will edit your header to correct it.
And so far as I have heard there are not much, if any Pt or Rh in organs, Pd, Au and Ag yes.

I see you have read Hokes, but if you are going to process you will need to read more than that.
here are some links:

We ask our new members to do 3 things.
1. Read C.M. Hokes book on refining jewelers scrap, it gives an easy introduction to the most important chemistry regarding refining.
It is free here on the forum: https://goldrefiningforum.com/phpBB3/viewtopic.php?f=54&t=19798
2. Then read the safety section of the forum: https://goldrefiningforum.com/forums/safety.47/
3. And then read about "Dealing with waste" in the forum: https://goldrefiningforum.com/threads/dealing-with-waste.10539/

Thank you Yggdrasil,
This board is not from organ, this is a "digitizer" that connected to yee old hp terminals.
Its like a big white flat thing you could draw on, with a red pen.
I have some more metall containing things from that thing.
There were wires on the board that connected to different parts of the traces, when i remove those there is a shiny silvery surface, inside there is some other red/orange metall.
one of the wires have a blue hue.
Will read the links.
Thanks

A jewelers test kit and stannous chloride can be used to identify precious metals in most all plating and alloys.

Example, gold plated copper. Use the 10K solution which is dilute nitric, dissolves base metals leaving gold foils or particles.

Example, palladium contacts. Use 22K solution which is nitric and HCl, dissolves all, then stannous check.

Use a magnet to check wheter this may be stainless steel or nickel (plated)
Try to dissolve them in HCl.
If they can withstand that, things get interesting (Maybe)

I am out of nitric at the moment, need to make some.
I will recycle this, and post.
Felt like its time to contribute to this wonderfull forum.

Not magnetic, But that reminds of something else.
I have contacts that is white/silver color, after hcl silver color disappear and they becomes between gold and metallic copper in color.
A very strange color, will take pictures

Try with HCl first, my guess is Silver, Pd or Tin plated wires.
HCl will reveal this.

Most stainless alloys are not magnetic.
They are relatively hard to bend though.

check with fire, for example with a turbo lighter.
any platinoids should remain shiny, silver will give a milky color.
