The rarest metal: Rhodium Rhodium is a rare and precious metal that belongs to the platinum group metals (PGMs), along with platinum, palladium, osmium, iridium, and ruthenium. Due to its scarcity, it is one of the most valuable metals in the world, often exceeding the price of gold. Rhodium is extensively used in the automotive industry to manufacture catalytic converters that reduce harmful emissions. Over the last few years, even with a steady supply, Rhodium demand has risen significantly, exceeding supply due to stricter emission regulations and advancements in the automobile industry. The significance of PGMs in South Africa South Africa is rich in various natural resources, such as metals and minerals. For example, almost all of the total global reserves of PGMs are in South Africa. In 2023, PGMs generated the highest revenue share in the South African mining sector compared to other commodities, amounting to 370 billion rands.
