Holding the breath, as far as i know, that's how they do it in Ghana

Some quick maths here for whoever in interested: If average CPU weight is 60g then that would mean there would be approximately 233 CPUs. They would have to be sold at about £20 each to have the same value as the gold resulted from the melting.maybe less if I knew how much silver was melted. So conclusion is that depending how old they are it might not be worth putting them back on the market and melting is better option. I did not take in to account the time and materials of the melting process as I'm not familiar with the costs.

As I understand, there are gold threads left inside the ceramic plates!!! You have only taken the visible parts with gold which is a loss. Try to crush the ceramic plates into fine powder and look for the gold that remains in the form of thin wire.

@OwlTech333

Жыл бұрын

There's no gold bonding wires inside the ceramics! From GRF "A standard ceramic CPU is made of several layers of ceramics bonded together. between the layers (while the ceramics is still unfired, also called green) is screen printed conductors of molybdenum. The ceramic body is then fired and the molybdenum that is exposed is then gold plated. On the bottom or side, pins are brazed or soldered and in the cavity bond wires are used to connect landing pads on the die with the exposed gold plated conductors. For bonding wires aluminum or gold can be used. Inside the ceramic body is the molybdenum conductors and the only gold is the exposed gold and the gold under the die. To use gold inside the ceramic body would be problematic. Thermal expansion and contraction will break conductors over time unless it expands with the same rate as the ceramic body. Molybdenum is the solution on this problem and it is cheaper that gold. Göran"

First time coming across something like this, needed to do some math.... Assuming 40 grams per CPU average, 14 kg would be 350 CPUs. From 91 grams gold that works out to about .26 grams of gold per CPU. That jibes with what I have seen reported elsewhere, at least assuming a high yield on recovery. Also, I never realized that these old CPUs contained about $15 in gold each.
