Final answer:
The Bushveld Igneous Complex in South Africa supplies about 70% of the world's platinum. It contains numerous precious metals and contributes significantly to the global economy.
Step-by-step explanation:
The Bushveld Igneous Complex in South Africa is the source of about 70% of the world's platinum supply. This large, layered igneous intrusion contains rich mineral deposits of platinum and other valuable metals like palladium, rhodium, gold, chromium, and vanadium.
Platinum is sought after for its industrial applications, including in catalytic converters in automobiles, lab equipment, electrical contacts and electrodes, and as an investment in bullion coins and jewelry. The platinum mining from the Bushveld Complex significantly contributes to the global economy and South Africa's national wealth. In contrast, the Democratic Republic of Congo leads in cobalt production, another critical mineral used in high-tech industries.
