Platinum is a silvery-white metal, lustrous, malleable and very ductile. In nature it is present in granules and is almost always associated other metals, it can be found mainly in igneous rocks and in alluvial deposits. Platinum is produced by extraction from reservoirs containing it, or through the refining of other metals such as gold, nickel and copper. This metal, in addition to being oxidized, is rarely attacked by acid and is therefore used for the preparation of highly resistant alloys, missiles, laboratory instruments and dental prostheses. In jewelry, platinum is used in the form of alloys, but is often replaced by palladium, which has a lower cost.
Native Platinum and its alloys have been known for a long time natural. The metal was known and used by pre-Columbian people South America and the first mention in European documents is 1557.
The English called the metal platinum, little silver, when they met for the first time in Colombia. The platinum was then considered an impurity junk silver and was often thrown away.
Platinum is often found in the native state or alloyed with iridium. It is often accompanied by other metals similar to it and is found mainly in alluvial deposits of the rivers of Colombia, Ontario and in some of the Ural mountains of western United States.
Industrially, platinum is a byproduct of the processing of nickel ores. Although the content of platinum is an average of two parts per million, large quantities of ore processed makes the extraction of platinum convenient. Description
