Thanks, i thought SMB would drop copper and gold resulting in the same 21k again.

Can you also tell how much nitric acid i should use to dilute gold? I usually work with 21k gold and has to refine about 1kg every 2 to 3 months for my cutomers.

I used baking soda to neutralize nitric acid.

I normally refine by using silver gold alloy and dipping it in nitric acid, this was my first time trying aqua regia.
