The first great platinum province

For over a century (1824-1925) the platinum-bearing belt of the Urals was the world's biggest producer of that metal. During this time about 400 tons of platinum were extracted, and thousands of platinum nuggets weighing 100 g to 1000 g were found; dozens ranging from 1 kg to 5 kg, and a rare few pieces that were close to 10 kg. Most of the platinum has been extracted from the extensive alluvial deposits discovered in 1823; the most easily accessible high-grade placer deposits have largely been exhausted and mining has now dwindled to a handful of small-scale dredging operations which produce only modest volumes of platinum. Primary mineralization is associated with dunite and chromitite within concentrically zoned complexes of Uralian-Alaskan type.

Recent additions to the Data Metallogenica database include new data galleries of maps and photographs from the general Ural Platinum Belt, as well as for several of the primary lode deposits such as Baronskoe-Kluevsky and Nizhni Tagil.
