Here's a bucket of crushed powder that I produced by running circuit boards through a ball mill and sieving it. The leftover small pieces of board that don't crush, but were worn 'clean', get leached in a separate bucket. You can clearly see metallics in the bucket. As well, you can see little 'plates' of scum.
In electronic appliances, printed circuit boards (PCB) represent an important component, containing high grade of valuable metals, besides organic resins and some ceramic materials. Copper is the major metal in PBC's composition (normally higher than 20% w/w) but many other secondary and minor metal elements, including precious metals, are found in PCB's.
