##### Where it comes from

Chart: Map of where it comes from

Rhodium is a small fraction of the platinum-group metals in Bushveld and Great Dyke reefs and Norilsk nickel ores. It is extracted only as part of mining for platinum.

##### Three things to know

1. The whole world mined only about 22.8 tons of rhodium in 2024, less than one-hundredth of gold.
2. Rhodium has no mines of its own; it is separated from platinum ores late in refining.
3. The US imported 14,000 kg of rhodium in 2025 but exported only 340 kg.

3. 3 **Matte**Smelted with nickel and copper
4. 4 **Long refining**Rhodium separated late in the sequence
5. 5 **Converters**Three-way catalysts in petrol cars
