Platinum-group metals (PGMs) are prized for their resistance to corrosion, durability and excellent catalytic properties. These characteristics make PGMs useful in everything from jewelry making to industrial and electronics applications, according to the US Geological Survey (USGS). Today, the automotive industry is the world's largest consumer of these metals, which are used in catalytic converters for vehicle exhaust systems. Automotive production is expected to climb in coming years, particularly in developing markets, and that is expected to ensure healthy demand for PGMs into the future. While the lion's share of the world's PGMs are produced in South Africa and Russia, there are a few other countries that chip into platinum and palladium production as well. Here are the top five platinum- and palladium-producing nations for 2014, as per data from the USGS. 1. South Africa Platinum production: 110,000 kilograms Palladium production: 60,000 kilograms South Africa is the world's leader in platinum production and holds the largest-known reserves of PGMs globally. With 63 million kilograms of PGMs in reserve, South Africa is equipped to remain a top PGMs producer, and currently extracts 78 percent of planet's platinum, according to the Chamber of Mines of South Africa. Last year, a protracted strike cut South African PGMs production by 33,600 kilograms. As a result, the three major platinum producers in the country — Anglo American Platinum (JSE:AMS), Impala Platinum Holdings (JSE:IMP) and Lonmin (LSE:LMI) — lost over $2 billion in revenue, according to The Wall Street Journal. 2. RussiaPlatinum production: 25,000 kilograms Palladium production: 81,000 kilograms Despite being the world's second-biggest platinum producer, Russia's annual production trails South Africa's by a large margin. However, Russia produces the majority of the world's palladium, and that has a significant impact on the global market.
