In the Jewelry, Dental, Pawn and Medical industries that
manufacture or repair precious metal products, having a sink trap
is a must. I have been surprised how many companies
neglect installing this simple contraption under their shop sinks to
capture micro fine gold, silver, platinum and palladium.
I had an opportunity to do a quick test with one of my dental
labs who recently moved. He reinstalled his old trap in the new location
and put in a new liner. We waited exactly a year before seeing what was
captured in the trap. This particular trap was set up where they cleaned off
their dental castings so the trap also served as a helpful device to keep
investment from going down the drain and clogging pipes.
There are a few different types of traps available with different
capacities and function. The one pictured here for this blog is what
was installed at the dental lab and is a common plaster trap that
will capture the casting investment and precious metal. The lab brought in the
liner and we processed finding over $750 worth of precious metal material
captured in the sludge. The trap was initially a $130 investment a few years
back and the replacement liners run approximately $30 each so it paid for
Whether you are a big manufacturer of just a one man outfit
there are some very effective sink traps you can get from most
jewelry tool suppliers. Companies like Stuller Settings, Rio Grande
and OttoFrei carry a nice selection of precious metal traps. I have also seen
some custom made and bigger scale traps for the large manufacturer.
Email me (firstname.lastname@example.org) if you are in need of a larger design and I will
send you information. A trap will also capture stones so I recommend having
one in the sink where your steam cleaner and ultrasonic are located. To save on
refining fees you may want to dry out the captured material before
you send it in to your refinery. The money saved by having a trap is well worth the time
spent installing, do not put off getting one any longer!
