Grinding down circuit boards? - Gold Refining Forum

Oct 15, 2009  I honestly don't think there's an economical/safe method, for a "garage" worker, to remove PMs from whole circuit boards. 1 - Incineration is out of the question, as it releases a whole host of very nasty fumes. So unless you have an industrial incinerator/scrubber, it's not a safe option. 2 - Milling the parts to smitherines is highly risk too.
