PGE deposits refer to concentrations of platinum group elements, which include platinum, palladium, rhodium, iridium, osmium, and ruthenium. These metals are valuable for their unique properties, such as resistance to corrosion and high melting points, making them essential in various industrial applications, including catalytic converters in vehicles and electronics. These deposits are typically found in specific geological formations, often associated with ultramafic and mafic rocks. The most significant sources of PGE deposits are located in regions like the Bushveld Complex in South Africa and the Norilsk-Talnakh area in Russia, where geological processes have concentrated these metals over millions of years.
