Erdenet (; Mongolian: Эрдэнэт [ért(ɘ)nɘtʰ], 'precious, valuable') is the second-largest city in Mongolia and the provincial capital of Orkhon. Located in northern Mongolia, it lies in a valley between the Selenge and Orkhon rivers about 240 km (149 mi) (as the crow flies) northwest of the national capital Ulaanbaatar and Darkhan. The road length between Ulaanbaatar and Erdenet is about 370 km (230 mi). As of the 2026 census, the city had a population of 112,520.
Erdenet’s identity is inseparable from the copper‑gold complex that gave the city its name. While most visitors glance at the towering slag heaps, locals see a daily pulse: shift changes dictate the rhythm of street cafés, and the whistle from the smelter marks lunch hour. This industrial heritage shapes everything from the modestness of housing estates to the prevalence of hearty, protein‑rich soups served in workers’ canteens. For the traveller, timing a stroll to coincide with the evening lull offers a quieter window to explore the city’s modest museums and riverside promenades, when the factory lights dim and the streets are lit by the soft glow of street lamps rather than the harsh glare of industrial floodlights.
Just beyond Erdenet’s municipal limits the Orkhon valley opens onto grasslands that still host seasonal ger camps. These are not tourist‑centric sites but working pastures where herders move livestock in response to the short summer rains. A respectful knock on a ger gives access to a tea ceremony where milk tea is poured from a brass kettle, and stories of the valley’s ancient trade routes are shared. The best chance to witness this exchange is in late June or early July, when herders return from high‑altitude pastures and the valley’s wildflowers are in bloom, providing a vivid contrast to the city's steel‑grey silhouette.
Most travelers reach Erdenet by road from the capital, yet the city’s railway line—built in the Soviet era—offers a quieter, more scenic alternative. The train hugs the Orkhon River, passing through pine‑clad hills and small villages where children wave from the platforms. On board, the rhythm of the rails mirrors the country’s own pacing, giving you time to read up on local customs or practice a few Mongolian greetings. Disembarking at the modest station, you’ll find a cluster of market stalls offering smoked meat and locally woven textiles, a reminder that the railway remains a lifeline for trade and cultural exchange, far beyond its original industrial purpose.

Located in northern Mongolia, it lies in a valley between the Selenge and Orkhon rivers about 240 km (149 mi) (as the crow flies) northwest of the national capital Ulaanbaatar and Darkhan. The road length between Ulaanbaatar and Erdenet is about 370 km (230 mi). As of the 2026 census, the city had a population of 112,520.
[edit] Erdenet, one of the youngest settlements in Mongolia, was founded in 1974 in an area where large deposits of copper had been discovered in the 1950s. A single-track railway line with a length of 120 km (75 mi) linking Erdenet to the Trans-Mongolian Railway was inaugurated in 1977. In the middle of the 1980s, more than 50% of the inhabitants were Russians working as engineers or miners. After the fall of Soviet Communism in 1990, however, most Russians left Erdenet. Today, about 10% of the population is Russian. Erdenet Mining Corporation[edit] Main article: Erdenet Mining Corporation The Erdenet Mining Corporation is a joint Mongolian-Russian venture, and accounts for a majority of Mongolia's hard currency income. Erdenet mines 22.23 million tons of ore per year, producing 126,700 tons of copper and 1,954 tons of molybdenum. The mine accounts for 13.5% of Mongolia's GDP and 7% of tax revenue. About 8,000 people are employed in the mine.
[edit] Erdenet is linked to Ulaanbaatar, the capital of Mongolia, and to the towns of Darkhan and Bulgan by a paved road and is easily accessible by bus several times each day. The distance to the capital where the nearest airport is situated amounts to 370 km (230 mi) and travel by car takes about eight hours.
[edit] Erdenet is home to several cultural and economic landmarks. The Erdenet Carpet Factory, established in 1981 about 2 km (1 mi) east of the city center, processes approximately 2,000 tons of wool annually and employs around 1,100 workers. Cultural institutions include the Mining Museum, located in the Palace of Culture on the central square, and the Museum of Orkhon Province, founded in 1983. The Friendship Monument, erected in 1984, stands on a hill in northeastern Erdenet. Amarbayasgalant Monastery, a major Buddhist site located about 60 km (37 mi) northeast of Erdenet, was founded between 1727 and 1737, partially destroyed in 1937, and restored after 1975 with support from UNESCO.
