Industrial uses of Rhodium are mostly as catalysts. Recovery of Rhodium from catalytic devices, in my opinion, is best left to the professionals, for a variety of reasons.
Another common use for Rhodium is plating of jewelry. When refining jewelry, recovery of Rhodium is not the target, regardless of price. Since it follows silver in most wet recovery procedures, it is recovered during refining of silver.
There are many other uses, but these are the most common.
I guess you will have to determine the plating of the contacts.
Example when doing military scrap electronics I was recovering 50 microns in 15 yrs the thickness on contacts was .025 the thickness was nothing in comparison.
Though it still had value.
It would be a great guessing time for the scrap value.
Making 3 inquiries for the product with 3 brokerages I dealt with.
Just like baseball-I'm out.
No interest in processing this type of contact.
Strangely enough
