Hi, I'm very new to this & the forum. Really hope someone would like to help or advise.
I have just finished dissolving a scrap pin melt in nitric acid. I have been left with a top blue liquid, mid dark blue/drown liquid followed by cloudy blue/black liquid & black particles or powder. Is this right & normal? Nothing I have read says anything about this or what I should do next. Where is the gold or did my melt not contain any? Thank you.
