Platinum group metals (PGMs) are a group of six precious metals that include platinum, palladium, rhodium, iridium, osmium, and ruthenium. These metals are known for their rarity, high melting points, and resistance to corrosion, making them valuable in various industrial applications, including catalytic converters in vehicles and electronics. PGMs are primarily mined in regions like South Africa and Russia, where significant deposits are found. Their unique properties also make them essential in jewelry and medical devices. Due to their limited supply and high demand, PGMs often have high market values.
