Been A while since I’ve been on here and in that time I started getting to know catalytic converters and processing them.
I first started out but just throwing everything in big container and trying to refine it without doing any kind of cleaning. I knew better and don’t know why I did it. But since then I started to do a HCl soak to rid of any contaminants.
I know that hydrochloric acid by itself will not dissolve gold,platinum or palladium or at least will not dissolve any amount worth worrying about, without it being mixed with another agent. So this is where I I’m confused.
I just tested a solution that has catalytic converter internans soaking in it with Stannous and got odd confusing results. Now in this solution should only be iron a little copper and maybe aluminum bc I only poured HCl on it. Not even water mixed with it and no heat at all except for what was generated by the reaction. My test pictures below. It starts as a lime green solution on q-tip then as soon as the Stannous is dropped on it,it immediately darkens then a orangish colors starts coming out and then goes the a orange stripe then orange green and then blue green.
Now everything I’ve read tells me that I have platinum and palladium in solution and the only thing I added was muriatic acid,nothing else. I wouldn’t think iron or even copper would do this bc I’ve tested acid peroxide for gold it never gave me results like this. I know I need keep reading and I’m fairly new to this but this one is a stumper. Thanks
