Awesome video. Great tip on cutting the silver buttons from the side's releasing them. I've never actually tried this. If I make a video, I'll mention try and remember to mention you.
I'll tell you a secret. Make a solution of copper sulfate and distilled water and , power supply unit at 2 volts. And refine the copper off of them first. You'll be left with clean silver buttons. Then when you refine the silver you won't have as much base metal to use up all your acid.
@@EstonianScrapper works like a charm bro. I electroplate parts for GM. Taught myself a lot of this stuff before hand so I didn't have to go to school for it.
Notice how those bars that the contacts came off of are very similar in color? They also contain silver. The copper wires may also have a slight yellow color to it also. More silver.
I did an experiment with 31.1 grams of very similar contacts from automotive relays. I got about 19.1 grams of cement silver and about another gram in chloride (didn't measure it) which by my math, is like %61 or so.......
I think its worth it. But if you count time maybe not. But you get some good copper and brass doing this too. I cut off the part with the silver contact and put the rest in the copper or brass pile. If you get older electronic breakers is no doubt worth it. But you need to have a good amount before can do any profitable extraction.
Yes.. many of those silver contacts are from a nowadays equipment and to get any profit out of them, you need a truckloads of those contacts, however, if you run across about 40 years old circuit breakers.. there is a nice amount of pure silver available.
@@mulhollanddrivehobo6910 if you count your time then not, silver is cheap and getting it off from contacts is not easy.. i do collect them just because i like any kind of silver contacts..
