Trade Platinum Group Metals
Platinum is a chemical element with the code Pt and Atomic No. 78. It is dense, flexible, ductile, extremely inactive, precious, silver-white metal transition. Its name is derived from the Spanish phrase Platinum, meaning "small silver". Platinum is a member of the platinum group of items and a group of 10 of the periodic table of items. It has six naturally occurring isotopes. It is a rare element in the earth's crust, with an average abundance of about 5 μg/kg. Occurs in some nickel and copper ores along with some domestic deposits, mostly in South Africa, which account for 80% of global production. Because of its scarcity in the earth's crust, only a few hundred tons are produced annually and, because of its important uses, it is highly valued and is a precious mineral commodity. Platinum is one of the least reactive metals. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Thus, non-biodegradable platinum is often found as the original platinum. Because it occurs naturally in the alluvial sands of various rivers, it was first used by native sands in South America before Columbus to produce artifacts. It was referred to in European writings as early as the 16th century, but it was not until Antonio de Ulloa published a report on a new metal of Colombian origin in 1748 that scientists began investigating.
