Just a guesstimate, but the ideal time to start up a refining operation would have been somewhere around thirty years ago ?

My sense of things is that chemical refining of PCB's is gradually giving way to a dry process that is more environmentally friendly.

I believe a chemical process is still required at some point. My understanding is that pins and fingers are gold plated. The gold would need to be dissolved off of the base metal to be recovered.
