Here is an image of the powdered material after incineration, washing, magnet removal of pins/legs, grinding, and sieving to 80 mesh. Can you see any bonding wires? What are all of those thin wire looking lines?View attachment 48819View attachment 48819
It looks like parts of the lead frames. Individual bond wires will be so small that you can't see them singly with the naked eye. Only after you have collected enough together will you see any gold color. You just have to accept that they are there on faith. If you leach the solids in nitric acid, any metallic color you see at the very bottom of the pile will be gold. After leaching with nitric acid and rinsing with distilled water, swirl the solids in a beaker and tilt to the side while the water and solids are still in motion. Any gold bonding wires will collect on the very bottom of the beaker. Lift the beaker and look at the bottom of the beaker. You should see some gold color in the lowest "corner" of the beaker.
