[QUOTE="AtomRat, post: 219501, member: 3111"] It looks like a high content of sulfides or chalcopyrite. Host rock looks interesting like a serpentine or granite? You can use the same chemical process to extract the au but you need to be careful of the reactions and fumes emitted from the rocks you are getting the color from. For example.. you've gotta watch out for arsenopyrite as it will fume arsenic.. other have a high amount of chlorine and other nasties. You need to look up your rocks and what's going to happen in the process or if you need to alter anything. Your still on a mission to make chloroauric solutions. If your dealing just with sulfides, they need to be roasted..again emitting nasties. Extracting the au and then testing the solutions with stannous chloride to test if there's gold in the solution etc just like refining ewaste process. I havnt tryed the smelting and 'dore' method yet in a crucible with borax [/QUOTE]
