Rhodium is a silver-white hard metal often found in platinum ores. It is the most expensive precious metal. In its natural solid state Rhodium is far too hard to work, but it is used as an alloy in the smelting of platinum and palladium.
Rhodium is a fission product in the decay of the isotope uranium -235, but only about 1% by weight, and most nuclear fuels only contain about 3% uranium-235, meaning only 1% of 3% of nuclear waste consists of this metal. Despite rhodium's great value, the cost of separating it out is generally greater.
