I recently came across some 10 year old enterprise grade server storage scrap.
The big circuit boards weigh about 5 lbs each. The edge connectors are all gold plated.
The back plane has a lot of gold plated flats and pins. I have about 150 pounds of boards.
We found a local metal recycle place that pays $3.50/lb for scrap circuit boards. I had asked about the pins/connectors gold content possibly making the boards worth more than standard desktop motherboards - but the reply was unless the surface of the circuit board is gold and not green, it's not a high grade board.
My idea was to cut off the plastic edge connectors and save all the back plane connectors, and try something like a copper sulfate electroplating cell to release the gold plating. Being computer servers, there are plenty of high current 5v and 12v power supplies to drive the cell.
I'm totally new to escrap gold recovery, and will appreciate any advice.
Thanks, William
