Thankyou Frank G, Michael M and Peter R for your comments,
Something I forgot to mention, our factory is in Bali, Indonesia. I
doubt if it would be worth shipping the dust to the US where the
established refiners are situated, and then shipping the refined
metal back through our less than accommodating Customs. Currently we
refine our trees, buttons and floor rejects at Logam Mulia the
largest refiner in Indonesia) but when we sent them our polish dust,
they refused to process it as is. Thus my conundrum! Any other ideas?
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?
