If you are trying to recover the gold from your bombing solution (Alkaline Cyanide & Hydrogen Peroxide). There are a number of electrolytic gold recovery units available. The resins are normally used after the electrolytic stripping to remove the last traces of gold. If your problem was due to incomplete stripping of your resin you may want to check with your resin supplier for proper methods. If you are burning your resin and trying to digest the carbon residue in aqua regia, it may take a number of digestion cycles to extract all the gold. I was in your factory about 8 years ago and at that time you were electro-stripping the pieces, the bombing process seems to be a step backwards.
