Hi guys,
First of all, happy new year !
I have been absent for a long time, I had so many things to change in my life!
Now it's done, I have got some free time to spend to scrap and refine PMs, and I am back on the GRF.
Today, I will ask you to help me to know wether the following e-scraps contain or not PM: gold, silver, tantalum, palladium or platinum!

Thank you in advance for your help, guys!

my questions:
- the black box: what is that ? is there any PM ?
- The "chrome tube": what is this metal ?
- The yellow tuff : is it tantalum capacitor
- the little ones black and white is there any silver ?

1.Black box metalized film capacitor, no precious metals.
2. Appears tome, to be a heat sink to keep electronic components to keep them cool or from overheating, the possible value in copper.
3. Metalized foil capacitor, aluminum foil capacitors.
4. looks to me, to be bare disk thermisters or possibly varistors (resistors that will change the value of resistance with temperature or voltage).

The components could be sold as used parts, but I personally do not see anything with precious metals involved or any tantalum...
