Here we are going after the gold on gold filled jewelry .
The jewelry was taken apart cleaned , dissolved in nitric acid , tested with stannous chloride , filtered then ferrous sulphate was used to drop the gold .
Ferrous sulphate drops the gold very nice .
Note : some of the 14K 1/20 jewelry was fake I should have tested it lesson learned .
This was added to the Pinless CPUS recovered gold and from cleaning up my AP bucket .
total yield of gold was 2.58 grams not bad !!!
Please don’t do this without the proper PPE , knowledge and a good plan . I assume no responsibility for any of your actions .
Thanks for watching
