Ural Cement Plant

The plant was initially known as Emanzhelinsk Cement Plant. Soon after construction, it was decided to expand the plant to a third and fourth production line. The plant's clinker burning capacity was 806 000 ton per year, and its cement production capacity was 900 000 ton per year.  A plan to expand the plant to a fifth and sixth production line with 4.5 x 170 kilns (design capacity of 806 000 ton) was developed on February 15, 1961. Primary processing equipment was supplied by Thalmann GDR plants, and the plant was provided with on-site railway lines and railway sidings adjacent to Klubnika Station of the South Ural Railway. 

On June 19, 1963, Emanzhelinsk Cement Plant was combined with a slate plant and renamed Emanzhelinsk Cement and Slate Works.  However, in 1967, the plants were split off, and the slate plant became a separate operation. As a result, the plant was renamed Korkino Cement Plant on August 4, 1967.

Korkino Cement Plant was incorporated on December 14, 1992, and converted into Open-Type Joint Stock Company Uralcement  (OTJS Uralcement). The new corporation was the successor of Korkino Cement Plant.

On December 30, 1994, Closed-Type Joint Stock Company Uralcement (CTJS Uralcement) was formed as a result of a merger of OTJS Uralcement and Cement Construction and Investment Company. Its form of incorporation changed from CTJS to Closed Joint Stock Company (ZAO) in 1996 due to amendments in RF legislation, and as of June 3, 1996, it was known as ZAO Uralcement.

In 2003 company again changed its form of incorporation from ZAO to Open Joint Stock Company (OAO), and on July 15, 2003, it took the name of OAO Uralcement.

In 2007, the General Meeting of Shareholders of Open Joint Stock Company Uralcement made the decision to: "Restructure OAO Uralcement by amalgamation with OAO Voskresenskcement and approve the unnumbered deed of amalgamation of OAO Uralcement and OAO Voskresenskcement of June 18, 2007, and the deed of transfer and acceptance of March 31, 2007." 

As a result of the restructuring, OAO Uralcement ceased operations on September 4, 2007, and became a branch of OAO Voskresenskcement, and later Lafarge Cement Russia (Uralcement Branch).  

The Sheinskoe limestone and clay quarry provides raw materials for the Korkino Cement Plant. The quarry is 1 km from the plant site. Limestone and clay quarries occupy 379.86 ha of the plant's total site area. Granulated blast-furnace slag from Chelyabinsk is used as an additive. Gypsum is brought in from the Erachevskoe deposit (Uralgips).  Pyrite cinders are brought in from Chelyabinsk Metallurgical Plant in Chelyabinsk, and Karabash; and refractory materials, from Magnezit Plant in Satka and Kyshtym Refractory Plant in Kyshtym.  Grinding media come from Katav-Ivanovsk. Gas from the Tyumen field via the Bukhara - Ural gas pipeline is used as process fuel.

The plant began operating on gas on November 20, 1964. Prior to this, plant No. 1 operated on coal; and plant No. 2, on fuel oil. Power is supplied to the plant from the 110/6 kV Pervomaisky substation owned by OAO Interregional Distribution Grid Company Urala - Chelyabenergo Central Power System. Groundwater reserves produced by artesian wells serve as the water supply source.

A lot of emphasis is placed on producing high-quality products, and thus the Quality Control Department and Laboratories are an important part of OAO Uralcement.  The Industrial Sanitation Laboratory is concerned with current environmental issues.

Health, safety and the environment are the core priorities of Lafarge Group. In order to improve environmental conditions at the plant and neighboring areas in the city of Korkino, Lafarge is implementing investment programs in the city; in particular, there are plans for full-scale replacement of the precipitators of seven clinker grinding units, silos and two crucial rotary kilns - 205 and 206. After more than 50 years of operation, the old filters have outlived their usefulness. New electrostatic precipitators were purchased from the well-known international supplier FLShmidt Airtech (Denmark) in order to implement this major 300-million-ruble investment program. The first electrostatic precipitator (205) at the Uralcement plant started up in December 2009. Despite the economic crisis, the work was carried out according to the initial plan. Replacement of the second electrostatic precipitator (206) began in February 2010. Pilot operation began on April 18, 2011, with final startup in October 2011.  

After electrostatic precipitator 206 was installed, the volume of dust emissions into the atmosphere decreased to 2.5 g/s (about 20 times less than before replacement).
