I've got 125 lbs. + of Tungsten evaporator filaments used to evaporate our Pd/Ag alloy ( 20/80 % )in vacuum .
The precious metals are infused into the multi strand wire Tungsten filaments .
Several recycler/recovery companies have turned down recovery of this ( " not our specialty " , Ewww Tungsten ! " , " Not enough weight " , etc. " We'll give you 70% of lowest market price . " , " We'll settle at N % of market price at some vague future date .. " and so on ).
I'm looking for a fair price and fast turnaround .
This scrap is used wire filaments . They are multstrand Tungsten wire filaments used to evaporate the Pd/Ag alloy to coat it onto customer parts for our antigalling coatings.
The alloy is evaporated at high temperature and gets infused and fused into the wrapped , twisted Tungsten strands of the coiled wire basket filaments .
Each filament has about 0.05 - 0.15 grams of Pd/Ag alloy on it .
Other than doing it myself are there any trustworthy companies that offer recovery and purchase of the precious metals on this material ?
In addition we can sell the Tungsten scrap
I also have several pounds of grinding from inside the coating chambers that contains about 7.5 % Pd , 58% Ag and 1-2% Au .
It also has Ni , Cr , Cu and Fe in it but not much else .
I would appreciate any valid leads on authentic , honest companies that purchase these materials at a high enough and fast enough payout to make it worthwhile.
Alternatively , is the best method to use Nitric to digest the Pd and Ag from the Tungsten ?
Or use cold AR ?
Or another stripping method ?
What is the Best way to dissolve the ground-off metal powder ?
Ball mill then AR ?
Then how to get Gold out ?
Then for both materials , what is the best way to separate Pd , Ag and Au at high purity for reuse or resale ?
We generate about 20-80 lbs of grinding and 60-100 lbs of coated Tingsten per year .
I appreciate any valid leads .
