ALUMINIUM SMELTER
URALS ALUMINIUM SMELTER
 The Urals Aluminium Smelter,
situated in Kamensk-Uralsky, is an alumina and aluminium complex, using
bauxites supplied from the North Urals (SUBR JSC) and Middle Timan (Timan
Bauxite JSC) mines. Commissioned in 1939, its main products are currently
alumina, primary aluminium, silumin and alloys. In 2008, the complex produced
133,600 tonnes of primary aluminium and 730,300 tonnes of alumina. The smelter
uses power generated by regional co-generation plants. The facility employs
2,900 people.

|
Kamensk-Uralsky is a town in the
Sverdlovsk region of the Russian Federation, on the south-eastern slope of the
Central Urals where the Kamenka River flows into the Iset River and
approximately 100 kilometres to the south-east of Ekaterinburg. It is a railway
hub and a regional centre with a population of 189,200. The town was founded in
1682. Its main industries are ferrous and non-ferrous metallurgy.
The territory of the Sverdlovsk region occupies 194,800 square metres. It lies
on the eastern slopes of the Central and North Urals and adjoining part of the
West Siberian Plain. Its population is 4.6 million people. The administrative
centre is Yekaterinburg.

Technology
The smelter’s aluminium production utilises electrolytic cells with self-baking
anodes and horizontal studs with an amperage of approximately 70 kA under the
Soederberg technology as well as electrolytic cells with prebaked anodes (160
kA). Currently, the smelter is undergoing a large-scale modernization
programme, which includes the reconstruction of existing production facilities
as well as the building of new ones. Modern electrolytic cells with prebaked
anodes (160 kA) are also being installed. This technology is used to produce
two thirds of the aluminium at the smelter.
A trial industrial complex with electrolytic cells using 300-350 kA technology
is also operating at the smelter.
In addition, a number of areas have been rebuilt in the past few years to use
modern Bayer processing equipment for alumina production.
Certificates
The Urals Aluminium Smelter is certified under the ISO 9001 quality management
standard and the ISO 14001 environmental management standard.
Development
In 2003, the Urals Aluminium Smelter finished the second stage of the
modernisation of its reduction technology which included the commissioning of
two potrooms containing electrolytic pots with prebaked anodes at an amperage
of 160 kA as well as dry gas scrubbers. As a result, production capacity was
increased by 35,000 tonnes per annum.
In 2005, a trial area containing electrolytic cells with prebaked anodes
(300kA) was opened. Prior to this significant work was carried out to improve
alumina production, including the commissioning of a filter and precipitation
module in 2001 and the introduction of a Cyclone calcination kiln in 2004 that
provides 80% of the alumina for the reduction process.
Environment
The Urals Alumina Refinery has three bauxite residue areas located approximately
6 km from the refinery, two of which are active. Other industrial wastes from
the plant are either taken to a licensed waste area for disposal, are recycled
back to the process (reduction plant sludges), or are sold to local recycling
companies.
In 1994, the smelter started to use two-stage gas treatment units for the first
half of its potrooms containing electrolytic pots with pre-baked anodes at an
amperage of 160 kA. In 2002, dry gas scrubbing was introduced in the second
half of the potrooms containing electrolytic pots with pre-baked anodes.
