Согдийская область
Tajikistan has rich deposits of gold, silver, and antimony. The largest silver deposits are in Sughd Province, where Tajikistan's largest gold mining operation also is located. Russia's Norilsk nickel company has explored a large new silver deposit at Bolshoy Kanimansur. More than 400 mineral deposits of some 70 different minerals have been discovered in Tajikistan, including strontium, tungsten, molybdenum, bismuth, salt, lead, zinc, fluorspar, and mercury. These minerals have been found suitable for mining. Uranium, an important mineral in the Soviet era, remains in some quantity but is no longer extracted. The Tajikistan Aluminium Company (TALCO), an aluminium smelter, is the country's only large-scale production enterprise in the mining sector. Tajikistan hosts the annual Mining World Tajikistan, an international exhibition on mining in Dushanbe.
