Of course ''CPU'' means different things to different people. I think of it from a microelectronics point of view.. There won''t be any gold to speak of in a silicon chip, but the packaging is a different story.. Gold plated contacts are used wherever good conductivity is required — and the high current consumption of modern cpu''s makes them ubiquitous.. But the gold plating is very thin.
Only one gold extraction method cannot be used to recover gold from all parts of computer. Nitric process or CN process can be used to remove gold from gold plated/polished pins and connectors.
