Rhodium, Ore

MOQ: 100  Metric Tonnes
Sample Available
Supplier From Calgary, alberta, Canada
 
Rhodium ore refers to naturally occurring rock that contains trace amounts of rhodium (Rh), a rare and valuable precious metal belonging to the platinum group metals (PGMs). Rhodium is typically not found in concentrated ore deposits on its own. Instead, it occurs as a by-product in the mining and refining of other PGMs, particularly platinum and palladium, and sometimes in nickel and copper ores.

Composition:
Primary Element: Rhodium (Rh)

Associated Elements: Platinum (Pt), Palladium (Pd), Ruthenium (Ru), Iridium (Ir), Nickel (Ni), Copper (Cu), and Gold (Au)

Typical Host Minerals: Sulfide minerals such as pentlandite, chalcopyrite, and pyrrhotite

Geological Sources: Rhodium is primarily extracted from sulfide ore bodies found in regions like South Africaâ??s Bushveld Complex, Russia's Norilsk region, and parts of Canada.

Uses of Rhodium:
Catalytic Converters

Rhodium is most widely used in automotive catalytic converters to reduce harmful nitrogen oxide emissions from vehicle exhaust systems.

Jewelry and Finishing

Due to its brilliant reflective properties and resistance to tarnish, rhodium is used to plate white gold and silver jewelry, giving a bright, durable finish.

Electronics

Rhodium is used in electrical contacts and connectors where high corrosion resistance and conductivity are essential.

Chemical Industry

Employed as a catalyst in hydrogenation and oxidation reactions, especially in the production of acetic acid and nitric acid.

Investment and Bullion

Given its rarity and high value, rhodium is also traded as an investment commodity, similar to gold and platinum.
