We refined some gold which contained more copper. After refining was complete, the decant solution was treated with sodium Meta Bi Sulfite and zinc.
But even after that some ppm gold and silver is showing in it. We have treated it 4-5 times, like for gold we added SMBS and Zinc and for silver we added NaCl and HCl.
I want to know why is this happening and what is the solution for this?
Au showing in it 4-5 ppm and Ag 25-30 ppm.
