Rhodium is the rarest of all non-radioactive metals. It occurs uncombined in nature, along with other platinum metals, in river sands in North and South America. It is also found in the copper-nickel sulfide ores of Ontario, Canada. Rhodium is obtained commercially as a by-product of copper and nickel refining.
What things contain rhodium?
These alloys appear in items such as furnace coils, aircraft engines, electrodes for aircraft spark plugs, and laboratory crucibles. The most common use for rhodium, though, is in vehicles’ catalytic converters, either as a standalone element or in tandem with palladium or platinum.
How is rhodium extracted?
Rhodium is extracted as a byproduct of platinum and nickel mining. Rhodium hydroxide is then precipitated out using sodium hydroxide, while hydrochloric acid is added to produce H3RhCl6. This compound is treated with ammonium chloride and sodium nitrite to form a precipitate of rhodium.

Rhodium is a platinum-group metal. In 2021, the supply of rhodium in South Africa is expected to reach around 624,000 ounces, making South Africa the world’s largest rhodium producer.
