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.
Time for more coffee.
