I am wondering if anyone recycles, or knows how to recover, silver
or gold from polish dust to reclaim lost metal? Our local refiner
doesn’t want to process the raw dust. Is there some process that can
be done to refine the raw dust so our refiner will process it? I have
maybe 30-40 investment drums full of raw polish dust. Anyone?
Hello Marcus: I use Hoover and Strong
http://www.hooverandstrong.com/. They have never turned away my
sweeps or buffer cabnet dust. If you work in primarily silver @ $4.65
an ounce, it might cost more to ship 30-40 drums than you will get
back. Just a thought. Michael R. Mathews Sr.
United Precious Metals 1-800-999-fine(3463). They will refine it.
They will come and pick it up when they have someone in the area and
they will pay you for the gold, and silver recovered or return
metals. Dave Zimmer ext 137 is my contact there and I have always had
good service and excellent customer relations with these people over
a 10-12 year relationship. Frank Goss

find a more competent refiner. Virtually any decent firm of any
real size and capability will take polishing dusts, and give you a
proper return on it. Note that the returns are less than for higher
grade metallic waste, like bench filings, etc, but it’s still quite
decent. My boss sends ours to Glines and Rhodes. Others I’ve dealt
with include David H. Fell, and United precious metals. There’s
plenty more refiners besides those. Glines and Rhodes even supplies
the shipping containers and arranges for shipment pickups.
As to doing yourself, refining low grade wastes is no where near as
easy as refining the high grade stuff, and even that isn’t totally
simple. I’d suggest just letting your fingers do the walking. Doing
it yourself would likely cost you more, and yeild lower returns than
sending it to a firm experienced in such waste. It sounds like
you’ve got quite a bit, so the potential loss from doing it yourself
might be quite significant…
