What is platinum? It is a rare, silvery-white precious metal (symbol Pt, atomic number 78) prized for its density, resistance to corrosion, and stability at extreme temperatures. Platinum belongs to the platinum-group metals (PGMs) — a family of six elements including palladium, rhodium, ruthenium, iridium, and osmium — and its supply, demand, and price behaviour are closely tied to that wider group.
What Is Platinum? Properties and Characteristics
Platinum has a melting point of 1,768°C and a density of roughly 21.45 g/cm³ — nearly twice that of lead. It does not oxidise or tarnish in air even at high heat, and it resists attack from most acids, dissolving only in aqua regia. These properties make it chemically inert enough for laboratory and medical use, yet malleable enough to be drawn into fine wire or hammered into sheet. Platinum is also one of the rarer elements in the Earth’s crust, occurring at only a few parts per billion.
What Is Platinum Used For?
The single largest consumer of platinum is the automotive industry, where it is used in catalytic converters to convert exhaust pollutants into less harmful emissions. Historically, palladium has substituted for platinum in gasoline-engine converters when relative pricing favoured it, and can account for up to half of the PGM loading in some diesel applications — a substitution dynamic that links platinum and palladium pricing closely together.
Beyond automotive use, platinum is a premier choice in fine jewelry because it is naturally white, hypoallergenic, and more durable than gold. Industrially, it is a key catalyst in petroleum refining and chemical production, and platinum compounds such as cisplatin are used in chemotherapy. The fastest-growing demand driver is the hydrogen economy: platinum is the primary catalyst in proton exchange membrane (PEM) electrolysers and fuel cells, positioning it as a strategic material for the broader energy transition.
Where Is Platinum Produced?
Platinum mining is highly concentrated geographically. South Africa is by far the world’s leading producer, hosting the vast majority of global PGM resources and reserves within the Bushveld Complex — mined principally from the Merensky Reef, Platreef, and UG2 Reef. Russia is the second-largest producer, with smaller volumes from Zimbabwe, Canada, and the United States. Because platinum typically occurs alongside nickel and copper ores rather than as a standalone deposit, it is usually recovered as a co-product of base-metal mining — meaning platinum supply cannot expand independently of the economics driving those base-metal operations.
Platinum Price and Market
Platinum trades as a precious-metal commodity under the ISO code XPT, alongside gold and silver, and is treated by many investors as a relative safe-haven asset. Current spot rates, historical trends, and currency and weight conversions are tracked on CMN’s platinum price page, updated monthly.
Platinum Supply Chain Risks
Supply risk is the defining feature of the platinum market. South African production has faced repeated disruption from electricity grid instability, labour disputes, rising costs associated with deep-level mining, and rail and logistics bottlenecks — all of which weigh on output even when demand is strong. The 2025 demerger of Anglo American Platinum into the independently listed Valterra Platinum illustrates how corporate restructuring within this concentrated producer base can itself become a market-moving event. Co-product dependency compounds the risk: because platinum output is tied to nickel and copper mine economics, supply cannot simply scale up to meet a demand surge from the hydrogen sector. Recycling offers a partial offset — platinum has one of the more mature recycling ecosystems of any critical mineral, with spent automotive catalysts a significant secondary source — but it remains supplementary rather than a substitute for primary mine supply.

What is platinum and what is it used for?
Platinum is a rare, dense, corrosion-resistant precious metal used mainly in automotive catalytic converters, jewelry, industrial catalysis, and increasingly in hydrogen fuel cells and electrolysers.
Why is platinum considered a critical mineral?
Platinum supply is highly concentrated in South Africa and mined almost entirely as a co-product of nickel and copper, making it vulnerable to disruption and unable to scale supply independently to meet demand.
Who produces the most platinum?
South Africa is the dominant global producer, hosting most of the world’s platinum resources in the Bushveld Complex, followed by Russia, with smaller output from Zimbabwe and Canada.
What is the current platinum price?
Platinum prices change daily. Current spot rates and historical trends are tracked on CMN’s dedicated platinum price page.
What are the main supply chain risks for platinum?
Electricity grid instability, labour disputes, and rising deep-level mining costs in South Africa, combined with platinum’s dependence on nickel and copper mine economics as a co-product.
Can other metals substitute for platinum?
Palladium can substitute for platinum in many gasoline and diesel catalytic converter applications, which links the pricing of the two metals closely together.
