Historical Reading List: Platinum from the Ural Mountains in Russia
April 8, 2019
Platinum is one of the most valuable of the precious metals because of its rarity and important jewelry and industrial uses. It appears to have first been recognized by the ancient inhabitants of South America who, prior to the arrival of European explorers, produced artifacts using a white gold-platinum alloy that was found as grains and nuggets in alluvial sediments along streams and rivers in the Andes Mountains.
The first known reference to platinum can be found in the writings of Italian humanist and scholar Julius Caesar Scaliger, who apparently saw the new metal while visiting Central America in 1557. He referred to a previously unknown metal (called by the Spaniards platina or "little silver") that the natives had learned to work with, but the Spanish had not. The name was given to the material because it got in the way during the alluvial mining of silver and gold. Since both the natives and the Europeans knew of no use for the platina, they thought of it as a nuisance and would discard it.
The first more complete description of the new metal was given by the Spanish military officer, scientist and explorer Don Antonio de Ulloa. While serving in South America on a scientific mission from 1735 to 1746, de Ulloa collected samples of platinum in New Granada (Colombia). Returning to Europe, he later wrote a report about the metal, describing both how it was mined and used. Although specimens of the metal appear to have been brought from Colombia to Europe after 1735, De Ulloa is often given credit for “discovering” platinum on the basis of this 1748 report.
Reports of the new element spread quickly through Europe. Scientists were fascinated by its physical properties, and within a few years when samples of the metal could be obtained, it became the object of numerous investigations. It was not only beautiful to look at, but resistant to corrosion, and with common heating techniques available at the time, it could not be melted.
The Ural Mountains, which extend a distance of about 2,500 km (1,600 mi) from the Kara Sea southward to the Kazakh Steppe, have long been considered by geographers as the “boundary” between Europe and Asia. For the past three centuries, these mountains have been an important source of gold, platinum, diamonds and other minerals. In 1819, platinum was first found alloyed with gold in placer deposits at “Verkisetsk” to the south of Ekaterinburg in the Ural Mountains (and a short time later, it was found as a pure metal). Within a few years, rich and extensive placer deposits in the region made large quantities of the metal available for the first time. These deposits occurred in association with outcrops of basic igneous rocks which were exposed near the summit and along the western slope of the Ural Mountains. It is now recognized that the deposits are related to several large igneous ultramafic-mafic complexes that extend over a distance of about 900 kilometers, with the region now known among geologists as the “Ural platinum-bearing belt” (the historically productive area in the Central Urals is contained within a length of about 130 km). The placer deposits are the result of weathering and erosion of the mountains over a long period of geologic time. Streams crossing these eroded igneous complexes carried away and concentrate platinum grains and nuggets in rich alluvial deposits. Records indicate that approximately 450 tonnes of platinum were produced in the Ural Mountains between 1824 and 1970. A very large platinum nugget, weighing approximately 9600 grams, was found in 1843 near the village of Nizhny-Tagil located 130 kilometers north of Ekaterinburg. In the early 1900s, this region of Russia produced approximately 95% of the world’s platinum supply.
Platinum is closely associated with five other rare metals (an often alloyed with) in nature – ruthenium, rhodium, palladium, osmium, and iridium. Collectively, this group is often termed the platinum-group metals.
How To Use This Reading List
This reading list was compiled to give you an opportunity to learn more about the history of platinum from the Ural Mountains in Russia. A number of the articles were published in the 1800s and early 1900s – when many classical gem deposits of historical importance were discovered – and gemology and mineralogy became sciences. The list is presented in chronological order to emphasize the development of ideas over time. The list is not comprehensive, but a compilation of the some interesting gemological information that has often been forgotten or overlooked.
Many of the articles exist in the public domain and can be found online at digital libraries such as Hathitrust, Internet Archive, or other digital repositories. More recent publications can often be found in libraries, including the Richard T. Liddicoat Gemological Library. Abstracts of these articles can usually be found on the website of the original journal or magazine, and the article itself is often available for purchase from the publisher.

Nineteenth Century Platinum Coins: An Early Industrial Use of Powder Metallurgy, H-G. Bachmann and H. Renner, Platinum Metals Review, Vol. 28, No. 3, pp. 126-131, (1984). When large quantities of platinum were found in the early 1820s in the Ural Mountains, there was at the time no significant industrial use of the metal, and the Russian government decided to use it for coinage purposes (as three, six and twelve rouble coins). Between 1828 and 1844, some 950,000 ounces of platinum were converted into coins which were to be used in place of gold and silver coins. These platinum coins met with little acceptance by the Russian public, however, and the government eventually called back and withdrew all of them still in circulation. After 1845, demand for platinum decreased in Russia, although small amounts were still used for other applications including jewelry.
