I have asked before about the separation of filings from silicon
carbide and other abrasives and got all the nasty chemical amswers.
I was wondering if there is a physical rather than chemical way to
separate the silver out of the filings mix. Such as panning or
washing? I notice that adding dish soap to a bowl of filings breaks
the surface tension and helps to let the things which float in the
water to fall, often the floating things hold onto silver. SI is
lighter than AG on the atomic chart but I don’t know about the
carbide part of the mix. It seems to me that panning would go a long
way to separation or sluicing somehow. What do you think?
