Hey everyone-
.......Yup another NOOB!
I have successfully performed aqua regia and ran into some issues in the melting process. It turns out I did not flux my crucible well, and the gold never made it out of the crucible in my drop in melting furnace. So when I melted a silver copper alloy down a few days later, it ended up mixing with the gold stuck in the crucible, and now i have gold silver and copper all mixed together in a a pile of shot i made with it and a small 1oz round I made with majority of the mixture. I heated the furnace to about 975 Celsius and then poured the mixture in an ingot, the excess was poured as shot...I also have some while coating on the metals, I'm guessing I used too much flux...?
So my question is where to go from here.. I would like to separate the three metals out and pour each individually into bars or rounds. If I was to guess my next step would be to put the metals back into AR mixture and first remove the gold with SMB..and melt the mud down after some washes in a NEW crucible. (BTW any insight in the best fluxing techniques would be appreciated...) After the gold is out, I was thinking to add copper pipe to AR (minus gold) and let the silver fall to the bottom, wash and melt in crucible just for silver. AND last the copper, I really have no clue what is going on with this.. I believe the copper burnt off in the gas emitted from AR?? I could be way off, not sure, but I'm excited to find out!! Please see attached photo. I BELIEVE there is 1oz of silver, around 5 grams of gold, and very little copper.....
