desovle gold to make pure 999.5 fine gold with shore mx3 kit

Im this video im using shore mx3 concentrate aqua regia kit. I use this kit because it cheaper and easier to get than nitric acid. It does take a little but longer to dissolve the gold but it does get similar results with less fumes and nitric acid. I always get pure 999.5 + gold. If you dont follow the procedure correctly it is possible to have contamination in your gold please subscribe!
