A customer bought an estate from an old refiner. The guy pretty much took everything and just tossed in into solution. Computer boards, intact watches, gold, GF, GP. All if it just went in. What I received looks like he started to filter out the gold and never finished. There was a bag of filters (pictures posted). Out of HNO3 so made poor man's AR. Dropped gold did stannous test was clear, after about 15min it became faint orange (pic below) now it's been about 45min and it's darker orange. That's pos for pbm correct? I still have some of the material to process. Pictures of the material i already processed still has some silver/white metal flakes that didn't go into AR thinking maybe 50% didn't. If it is, how do I get the pbm out of AR and is there different steps i should do before putting the rest of the material in AR? I Have hokes and plan on going through again but I learn better from others knowledge mixed with book reading
