I tried my first incineration yesterday and What remains I haven’t the slightest clue what it could all be. The material is from wholes circuit boards (compacitors and iron removed) that have been in a 5 gallon bucket soaking in an AP solution for probably 3 years. Old boards were removed and new put in. It wasn’t just the same boards so I had a little bit of material in the bottom of bucket.I added fresh acid and hydrogen peroxide 3%, periodically buy still a small amount of remaining copper with a bunch of what I would call gunk in the bottom. After filtering and rinsing with water I dried the material in a pot and took a small sample that brought out back and set on top of my crawfish cooker and cranked it up. I set it up to make sure it got plenty of oxygen to hopefully oxide and burn off the stuff you don’t want. I guess it’s its safe to say I burnt off some of the stuff you don’t want to burn off but little if any was blow out buy the terbulance. I could be wrong though. I took a glass rod and crushed everything up and reheated and repeated.Now I’m guessing at what I am looking at the leftovers. I would very much appreciate it if you experienced guys could take a look at the picture and if you feel comfortable give me an educated guess of what it could be? This AP process was started before I had any knowledge of the effects of tin in a solution with gold. I jumped in head first without knowing the basics and that’s my fault and bc of this site I’ve learned a lot,but,I’m stumped on this one. I don’t mind reading so if you can only point me in a direction I’ll most certainly appreciate that too. Thanks
