Bob, apart from the use of silver as a connector coating, I don't know where the silver comes from. Some military specification co-axial cable had silver plated wire shielding. I did a lot of recovery from PCBs a few years ago and on average the PCBs contained 2 Kg silver per tonne (ie, 2,000 ppm). These boards were 10-20 years old. They also contained quite a bit of palladium, traces of platinum and rhodium. I suspect that a lot of electronic bits and pieces (and semi-conductors) contain platinoids, but the use is a proprietary secret. In 1990 rhodium skyrocketed to US$7,500 an ounce - somebody was caught short and had to buy up all available rhodium - I presumed it was a semi-conductor maker.
