Refining of Precious Metal


Dear Sir :

I want to get some information on refining of gold, Silver and all kinds of precious metals. Also I want to know the method for making PSC, PGC, Palladium Salt and so on.

I think you will find that those who have "real" information on how to refine precious metals are very stingy with it. Unless you are willing to pay a consultant you may not hear very much that is useful.

However, there was a book published by Hoke some years ago that I have seen advertised, I think in Metal Finishing Magazine, that is supposed to be good on the basics. I have never read it so I can't provide a good review.

If you are serious about your pursuit of this knowledge, e-mail me. I worked in a PM refinery some years ago and have accumulated some additional literature myself. Unfortunately I am one of the stingy ones who is not about to give away years of experience for free, especially not over the internet.
