They could easily be sold for much more than the value
of the metal
recovery. ?eBay has them going for $8 to $50 or more each. ?Also amateur
gold scrappers have a nasty habit of making a mess with their chemical
waste.
I do not think you understood the first time I said this.
Most guys buying chips and boards today use refineries, and have
stopped doing the refining at home. There are still a fair number of
independents doing the chemistry in their basement, but most have
figured out that using the commercial refineries is better in many
ways.
The refineries are actually quite clean, considering the toxic nature
of the business.
