This was my 3rd experiment with plated gold electronic waste. This batch was soft flexible plating so first I burned off the plastics, rinsed then processed 52g of material with 150 ml of AR. All was going well until after filtering & testing. I DeNOx with sulfamic acid and diluted. Upon adding SMB (strong sulfur smell)it failed to drop. I decided to cement it out with copper. I let it stay in for. 36 hours and filtered the cement. While filtering the last I accidentally picked up a beaker that had some used stock pot liquid in it and added it by accident. Instant color change to a two density layer fluid, one Red & the other Greenish Blue. I put the failed drop in a separate container to determine what element I have and handle appropriately. Thanks in advance
