Hi,
I melted al my buttons from last year and poored shots from them, dissolved them in AR en dropped the gold with SMB. Washed the the gold 3 times boiling water, 3 times hot Amoniak (10%), 3 times boiling water, 3 times hot HCL, 3 times boiling water, 3 times cold HCL and 3 times boiling water.
According the XRF there is 98,65% Au and 1,327% Ag.
Gold was from different gold plated pins, gold plated jewelry, Gols filled and carat gold.
Where did i go wrong that there is still that much Silver?
Thanks
