Base metals

[Sjeepboy]

I am wondering if muratic acid alone will dissolve the base metals out of old electronics? If there is another chemical I need to add that won't dissolve out the gold, what is it and what ratios should I use?

Okay on the double post, still trying to get the hang of things on this forum.

I have done a search and not having much luck, I hope that someone can give me a clue. I am definitely on a learning curve and have messed up several batches. So I am trying to go back to the start and fix my whole process.
