Hello all, new guy here, just started a job soldering all day here in colorado and have always been interested in getting gold out of this stuff. I always heard it is not profitable unless you get it for free and I can get a lot for free. I trim pins and break boards ends too that have little gold buttons on them and are underlain in copper. I am very new to this but here are some pics of what I got today if that helps and I would love some advice on if this stuff is worth it to process? Thanks! Pics were too big to upload but here is an imgur link imgur.com/a/ckufJ6V
