Platinum
Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. It has six naturally occurring isotopes. It is one of the rarer elements in Earth's crust, with an average abundance of approximately 5 μg/kg. It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa, which accounts for 80% of the world production. Because of its scarcity in Earth's crust, only a few hundred tonnes are produced annually, and given its important uses, it is highly valuable and is a major precious metal commodity.
Economy of South Africa
In 2008, South Africa's estimated share of world platinum production amounted to 77%; kyanite and other materials, 55%; chromium, 45%; palladium, 39%; vermiculite, 39%; vanadium, 38%; zirconium, 30%; manganese, 21%; rutile, 20%; ilmenite, 19%; gold, 11%; fluorspar, 6%; aluminium, 2%; antimony, 2%; iron ore, 2%; nickel, 2%; and phosphate rock, 1%. South Africa also accounted for nearly 5% of the world's polished diamond production by value. The country's estimated share of world reserves of platinum group metals amounted to 89%; hafnium, 46%; zirconium, 27%; vanadium, 23%; manganese, 19%; rutile, 18%; fluorspar, 18%; gold, 13%; phosphate rock, 10%; ilmenite, 9%; and nickel, 5%. It is also the world's third largest coal exporter.
