Dear members :
I was refining gold foils from old memory ship and other plated gold stuff , i used Aqua Regia to dissolve the material.
So like usual i neutrelize the acid ,precipitate the gold with copperas , then i washed the material and i end up with this...."photo bellow"
The problem is when i melt the final material with borax i get gold with iron and little of copper...??!!!!
Could anybody tell me why?and what should i do?
Thank you guys.
