We have a large filter with about 6 bags and are wondering if
anyone else found it profitable to refine the bag. With the cost of
refining...about $100. and the cost of new filter bags...about
$500...we are delaying the work. Please let me know your
experience with this issue.
My polisher is smaller, but I hate having to buy new filter bags
just because I want the gold out of them. Instead, I put a good HEPA
filter (actually, I double them up, so it’s two of them) in a shop
vac, and carefully vacuum the filter bags as clean as I can. While
there will be some waste that remains, this seems to get most of it,
and then I don’t have to replace the bags. Remaining gold will get
refined eventually, perhaps the next time I clean it all out. I’d
replace the bags only if, after such a cleaning, the suction power is
not up to what it should be, indicating that the pores in the bags
have become too clogged. If that’s the case, then it’s a no-brainer.
Refine em and replace em. But don’t send them seperately, send them
along with all the polishing dust the filters collected too. That way
you’re not paying extra just to refine the bags themselves.
My 2 cents…
