Tellurides possibly. North Carolina Eastern slate belt area, foothills,

[dingo1989]

So I've roasted these au/again ECT? probably twice and I've done the acid boil, first just using hydrochloric. And I've did an rinse with ammonia next I'm going to do a sulfuric acid boil. And then I'm going to roast it on high heat one last time and then the final rinse before I'm going to smelt it for my first time. I think I messed up last time because first of all I didn't have the right collector metal and I didn't smelt it long enough. Does 2 hours sound about right cuz I think I only did like 45 minutes or something. I'm still new to this but I'm doing everything I'm doing it all and all my cards are on the table I've had way too much time in this and it's killed my arms and all my ligaments are ripped in my shoulders it's just been tough but only from the love of it it's not about a dollar but now it's going to have to be part of it so any help would be appreciated here's some of the rock pictures that I've got associated with the area like I said this is in the foothills of North Carolina 28681 area code thank you very much have a nice day

My only comment , I’d be very very careful putting rocks/ ore in acids unless you know what you have as in what the rocks makeup is, arsenic is very common among other toxic elements that acids can and will release.
