It has two official names used by its people. In the Kazakh language, the name is Oskemen. In Russian, the name is Ust-Kamenogorsk. This Russian name comes from words for mouth, stone, and mountain. Both names are shown on the official seal of the city.

The city has a very long history that began in 1720. It started as a fort and a trading post called Ust-Kamennaya. A military leader named Ivan Mihailovich Likharev led an expedition there. He was searching for gold near Zaysan Lake. The fortress appeared on maps of the Russian Empire at the southern end of the Irtysh line. Later, in 1868, the city became the capital of the Semipalatinsk Oblast. It was also the place where Georgy Malenkov lived during his exile. He even managed a local power plant during that time.

Today, Oskemen is a major center for mining and making metals. Many large companies work there to process materials like zinc, copper, and lead. One big company is Kazzinc, which was formed in 1997. It was made by joining three other metal companies together. The city also has the Ulba Metallurgical Plant. This plant makes special items for electronics and engineering.

It also houses a very important uranium bank. This bank holds 90 metric tons of material. This is enough to power a large city for three years. The project cost $150 million to fund.

Life in the city can be tough due to the heavy industry. The air often contains many different substances from the metal factories. This can make the air quality quite poor in some areas. The rivers near the mining sites also face pollution from industrial waste. Because of this, some water intakes in the western part of the city are closed. The weather is also very extreme for the people living there. It can get as cold as −49 °C in the winter. In the summer, it can reach a high of 43 °C.

Even with hard work and tough weather, people enjoy many activities. Oskemen is a very famous place for ice hockey. Many players who reached the NHL grew up in this city. You can watch teams play at the Boris Alexandrov Sports Palace. There are also football teams and many museums to visit.

The city has many different groups of people living together. You can find both Russian Orthodox churches and mosques. There are 32 different religious groups in the city. This makes the culture very rich and varied.

Oskemen is the largest city located in eastern Kazakhstan. It serves as the administrative center for the East Kazakhstan Region. The city sits at a vital geographic junction where the Irtysh and Ulba rivers meet.

It holds two official names used by its residents. In the Kazakh language, the city is called Oskemen. In Russian, the name is Ust-Kamenogorsk. This Russian name is derived from words meaning "mouth," "stone," and "mountain." Both names are displayed on the official seal of the city.

The history of the city began in 1720. It was originally founded as a fort and a trading post named Ust-Kamennaya. This establishment followed an order from the Russian Emperor Peter the Great. He sent a military expedition led by Major Ivan Mihailovich Likharev to search for Yarkenda gold. Likharev's group traveled up the Irtysh River toward Zaysan Lake. The fortress was placed at the junction of the Ulba and Irtysh rivers. By 1868, the city became the capital of the Semipalatinsk Oblast. Later, it became the site of Georgy Malenkov's 30-year internal exile. During this time, he managed a local hydroelectric plant.

Oskemen is a major industrial center for mining and metallurgy. The city's post-war history is closely linked to the Soviet nuclear project. Because of this, the city was once closed to outsiders. Today, it processes many non-ferrous metals. These include uranium, beryllium, tantalum, copper, lead, silver, and zinc. The Ulba Metallurgical Plant is a leader in producing high-tech products. These products serve the fields of electronics, metallurgy, and atomic engineering. The plant also hosts a critical international facility. This is the Low Enriched Uranium (LEU) bank. This bank is a physical stock of 90 metric tons of LEU hexafluoride. This amount contains enough uranium to power a large city for three years. The facility was funded by IAEA member states for $150 million. These funds are expected to cover costs for 20 years.

Large companies drive the local economy through integrated production. Kazzinc is a major producer of zinc. It was established in 1997 through a merger of three metal companies. These were the Ust-Kamenogorsk Lead and Zinc Combinate, the Leninogorsk Polymetallic Combinate, and the Zyryanovsk Lead Combinate. Kazzinc aims to be one of the five lowest-cost zinc producers in the world. The city also features a specialized Titanium-Magnesium plant. Around the region, there are five hydropower plants and many thermoelectric power stations. One notable feature is the Oskemen Lock at Ablaketka. This is the highest lock in the world. It allows river traffic to pass a hydroelectric dam on the Irtysh river with a drop of more than 40m.

Industrial activity has created significant environmental challenges for the city. The atmosphere contains by-products from heavy metal production. These include nitrogen dioxide, sulfur dioxide, arsenic, and beryllium. There are approximately 170 polluting components found in the city. Air pollution is prevalent due to low urban ventilation. The city is often recognized as one of the most polluted in Kazakhstan. Radioactive anomalies also exist due to the production of uranium, thorium, and radon. The soil in industrial areas contains solid wastes that are unfit for planting. Furthermore, the rivers in this region face high levels of surface water pollution. Contaminants like lead, selenium, and cadmium spread for many kilometers. Consequently, some drinking water intakes in the western part of the city are closed.

The city is home to a diverse population of 378,161 people. As of 2025, Kazakhs make up 51.51% of the residents. Russians represent 43.51% of the population. Other groups include Germans, Tatars, Ukrainians, and Azerbaijanis. Religion is also varied, with 32 different religious unions. Orthodox Christianity and Sunni Islam are the main religions. The city contains 21 cultural buildings, including mosques and Orthodox Christian churches.
