I've been saving these up for a little while. I forgot to weigh them, but theres a couple hundred in the mortar.
You are going to need a huge amount of these for anything signifigant to add up, since each LED look like they only contain 1-4 bonding wires.
The way I'm doing it, is just for recovery of the bonding wires and tiny chips, to refine at a later time. (No chemicals needed)
Lightboard from a flatscreen TV. Depending on the size of the TV, you'll get more or less boards and they come in different lengths.
Slide a small straight screwdriver underneath of the plastic cover and pop it off to expose the LED.
Take a small pair of jewelry cutters "edge nippers", or a screwdriver etc, and remove the plastic disc. The white plastic is very easy to break apart. The small yellow circle in the middle seems to be a type of glue. The bonding wires are in this part.
There is a small bit of metal left on the board after the disc is removed, I haven't tested this piece yet to see if the solder contains silver or not.
Just for size reference.
