James, great photos. Could you please tell us what we are looking at?

Silver,
From my very first burn of 630.89 grams of ram chips (DIP and BGA types).
I burned too hot (venturi throttle wide open) and too fast (30 mins.) and had the chips piled up too much so I ended up with an incomplete incineration.
So I pulverized by hand as best I could and sieved everything. These are the heavies from my +12 screen.

Still new to the ewaste gold recovery field, so I'll try my best at individual identification. Perhaps the more experienced can help?

I have found solid gold bonding wires, but in a much finer screen size. I don't have any pics as I took all my screen sizes and ground everything in my sophisticated grinding apparatus (a coffee bean grinder liberated from my wife’s kitchen :shock
. She doesn't like coffee anymore, so I think I'm OK :? All that is left is +100 and -100 screen material - still playing with it all.

Thank you!kernels said:
It helps to have a good stand.

I'd be interested in hearing more about the digital microscope. What model? Do you view the picture on a laptop or tablet? Cost? Etc. The color and clarity is much nicer that the one I am using.

I am using a Plugable 250X USB Microscope http://plugable.com/products/usb2-micro-250x/
I don't use the stand that came with it, but, instead, I bought a Aven 26700-312-LED 3D Stand with LED for Digital Microscope http://www.aventools.com/product/3d-stand-with-led-for-digital-microscopes-and-cameras/ To me, it was worth the extra $ to get the articulated arm, heavy black stand and the extra LED light.
I attach the camera to my laptop and use the camera's software to set-up the shot and adjustment. I shoot through the computer and software (you can also shoot by touching the camera) so as to not move the assembled shot.
You can also use the camera in the wild via a smartphone.
Lighting is very important.
