- Аннотация: From 1991 to 2021, Russia produced nearly 6,500 t (209 million ounces) of gold, about 7.5% of the total world production from a territory equivalent to 11% of the landmass. Russian gold production increased faster than that of the rest of the world (2.3 times vs 1.65 times).Russian gold was extracted from more than 100 hardrock deposits and numerous placers in eastern Siberia, Far East and the Urals. The hardrock sources included epithermal, orogenic, Carlin-like(?) and intrusion-related types, with gold as the principal metal. By-product gold was extracted from Cu-Fe skarn, Cu-Zn VMS, magmatic Ni-Cu-PGE sulphide, and recently developed porphyry Cu deposit types.In 1991, placers contributed 79.2% of 143.1 t of Russian gold. In 2021, their share had decreased to 24% from the total of 331.1 t Au, approximately 30% less than in 1991. The most dramatic change was in gold production from hardrock deposits, with a 7.3 times increase from 34.3 t (in 1991) to 250.9 t (in 2021).
