Nitric process can be used for removing gold from different kinds of gold plated connectors and pins, if the gold polish is thick and base metals are present.

Base metals (copper etc.) get dissolved in it, which can be recovered in the end. First gold should be recovered because the worth of gold is higher than copper present in the solution. No need to worry about copper and brass dissolved in the solution because we will easily recover all that after recovering gold. Kindly contact us to know the complete process.
