Leninabad Mining and Chemical Combine

The Leninabad Mining and Chemical Combine was a uranium processing plant in the Soviet Union. It was founded in 1945 in Leninabad, Tajikistan, as a hydro-metallurgical uranium enterprise to exploit uranium deposits across Central Asia. It was the first plant in the Soviet Union to produce yellowcake (a concentrated form of uranium).

The plant provided material for the Soviet Union's defense and power industries, and contributed to the production of its first nuclear bomb test. By 1953, it annually processed up to 1,000,000 tons of uranium ore. Operations stopped in 1992 when uranium mining ceased in Tajikistan. The plant left an environmental impact by dispersing radioactive waste into the surrounding areas, which has posed health hazards to nearby communities. Its successor, IA Vostokredmet, focuses on underground metal heap leaching.
