Hello everyone!
I received 3 kg of capacitors to recover the palladium. I tried a 100 g sample and didn't succeed in the recovering.
My question how do you differentiate between two brown smd capacitors, the ones that contain palladium and those who don't?
Here's a photo of the lot:
I know that there's a lost inductor here and there (marked in red), but the majority is small brown smd capacitors.
From a sample of this picture, the stannous chloride test failed and DMG test failed.
The capacitors were boiled with 5 times its weigh in volume of 38% HCl, they disintegrate leaving only the ceramic foils, which in the aqua regia digestion they all became a white powder.
Thanks!
