The Tumurtein iron ore mine is connected to Ulaanbaatar via both railway and road networks, passing through Darkhan. Darkhan and Ulaanbaatar are 230 km apart and linked by both rail and paved roads. The distance to Darkhan-Uul province is 130 km, while the Ulaanbaatar-Sukhbaatar highway runs 80-85 km from the mine.
Located in Bayantsagaan 2nd bag, Khuder soum, Selenge province, the Tumurtein mine operates under special license MV-013319, covering an area of 1,200 hectares.
The mine consists of two main ore bodies—Eastern and Western sections, which belong to the same ore zone and are located 2.0-2.5 km apart. The geological characteristics of the Tumurtein mine were first mapped by Yu.P. Yershov (1962) and B. Jamba (1968-1969). Further assessments were conducted in 1969 through airborne magnetic surveys and prospecting. Between 1979 and 1984, general exploration, resource evaluation, and preliminary studies were carried out, followed by detailed exploration between 1990 and 1992, confirming the mine’s reserves.
Mining operations officially began on September 23, 2010, when the open-pit mine was inaugurated.
The Tumurtein mine consists of: An open-pit mine, a dry magnetic beneficiation plant, a maintenance center, a worker’s settlement, a substation and infrastructure facilities. With a production capacity of 2 million tons of iron ore per year and an equal processing capacity of 2 million tons, the mine operates using modern, high-efficiency equipment. A workforce of approximately 490 employees runs operations on a 14/14 shift schedule. On July 1, 2014, Tumurtein began processing iron ore using a dry magnetic separation method.
The beneficiation plant utilizes TRIO-brand equipment from the United States, with a processing capacity of 750 tons per hour.
