Mining Significance
Rhodium is a scarce platinum-group metal recovered almost entirely as a coproduct during mining and refining of PGE ores. It occurs at very low concentrations in PGM-bearing magmatic deposits and is separated only after multiple concentration and refining stages. Its rarity, difficult separation chemistry, and dependence on broader PGM production make recovery efficiency and refinery capability especially important.
