Filtration problems and small gold particles in solution
10. This time, I saw little shiny gold at the bottom of the beaker. 11. I discarded the gelatinous solution by decantation and dissolved the gold in aqua regia. The total sample was 600g. The first run was 400g and yielded 1g of gold. The second run was a 200g sample, yielding 0.5g of gold.
