I've purchased and read several different reports including information listed on this site about using Muratic (HCl Acid) + Nitric and or H2O2 (Hydrogen Peroxide) for removing gold off pins and CPU's.
I am trying about 5 different batches of this stuff in an attempt to find a good recipe. One batch that has me baffled is using the following mix:
1 part HCL (33% Muratic)
4 part distilled Water
1 Tablespoon of Sodium Nitrate (for Nitric Acid)
1 part H2O2 (3% peroxide)
In this solution I have several CPU's. After 2 days the pins are just gone but there appears to be no gold in the solution which has now turned a greenish color. So I wonder if this solution has dissolved the gold?
I'm guessing some of the more experienced gold refiners will know. Will a solution of HCL, Nitric and H202 dissolve gold into solution?
And is there any mix of chemicals I should be using to remove gold from pins and CPU's instead of this mix considering I don't want to use something like Aqua Regina due to fumes.
