Maybe, yes, no. This one is almost a FAQ...

See Howard Manko, Solders and Soldering, 3rd ed., 1992 McGraw-Hill ISBN
0-07-039970-0. Howard covers the subject quite well. If you were to solder
boards continually with gold plating, it would eventually build up in the
wave solder pot to the point you would notice the granularity in the joints.

Also see http://jefry.ipc.org/archives/technet.html and search the topic gold.

>Doesn't alot of the gold just end up being dross?

I believe most of the gold would stay in solution in your pot.
