I am stuck in a process and need some insight.
I am processing a material that is 8k gold and the rest silver. It is from a mine, but I made sure there were no contaminates like lead or mercury. I analyzed the sample myself and it is pure gold and silver.
I made the material into shot form and took 125 grams of it and boiled it in 275 ml of nitric and 275 ml of distilled water. After about an hour boil I let it set overnight. I have attached pictures of what happens.
I am wondering why my material is covered in salt? I drained the acid to be processed to remove the silver. I boiled in distilled water twice the original material. Most of the salt remains.
What am I doing wrong?
I gave up on the salt and processed the remainder of the material with AR. Much gold dissolves but only makes it up to about 92% purity. A gray porous material remains, much like that of scrap jewelry that gets the typical silver protective layer. When I melted this material, its about 47% gold and 53% silver.
I am very new to this, though I had the AR process down. Inquarting isn't quite working out for me.
Any thoughts?
Oh BTW, I have a Fischer XAN120 XRF for my assay. So yes I got a very good idea of what I am looking at.
