Is anybody recycling drilling dust? Ours contains no gold and nobody I contacted locally wants it because it is too dusty. It probably would not be cost effective to send it a long distance. The result is that we send it to an industrial landfill.
I would be interested what others are doing with this material.

What we've found in trial evaluation with some recyclers is that
our dusts are about 10% copper, and that the most cost effective means
of transporting and recycling them is in "super sack" type containers.
(This is also true for dried sludge.) With this type of packaging, you
can avoid the dust exposure issue both on our end and the recycler's
end.We envision that without RCRA dictates on the WWT sludge, that we
can commingle these two copper rich commodities and minimize shipment
costs by shipping full truckloads (or railcar loads) of the commingled
materials.
Without RCRA regulation limitations, PWB manufacturers could also
form recycling consortiums to further minimize not only transportation
costs, but also on-site storage space of these materials. Lee Wilmot

Brad,
Besides the demonstration of an expedited delisting of our F006
sludge, another integral part of our Project XL project is to see if
we can cost effectively recycle copper bearing dusts, whether they be
from drilling, edging or sawing. We will determine if the cost saved
by managing a delisted WWT sludge is enough to start recycling the
copper dusts. We've committed to recycling $ for $ all the dust that
we can cost justify.
