Remarks |
18.5 MW steam turbo-generator Extraction of uranium using the ISR mining method requires substantial amounts of sulfuric acid. If sulfuric acid is unavailable, it could impact the Group’s production schedule, while higher prices for sulfuric acid could adversely impact the Group’s profits. The Group’s weighted average cost of sulfuric acid increased slightly to KZT 22,203 per tonne in 2020 (from KZT 21,304 per tonne in 2019). On average in 2020, the price of sulfuric acid represented about 13% of the Group’s uranium production costs. |

January 12,
2024 - The world's largest uranium producer, Kazakhstan's
Kazatomprom, said on Friday it may cut its 2024 production plan due to
difficulties with the availability of sulfuric acid needed for uranium
production. The company had previously predicted that uranium
production in the country would be 25 000 t to 25 500 metric tons this
year and 30 500 to 31 500 t in 2025, compared with 20 500 t to 21 500 t in
2023. In a statement, the company said: "Despite the ongoing active
search for alternative sources of sulfuric acid supply, current forecasts
indicate that the company may find it difficult to achieve 90% production
levels compared to subsoil use contract levels". Kazatomprom, which
floated shares on the London Stock Exchange in 2019 and is 75% state owned,
mines uranium in Kazakhstan both independently and through joint ventures. March 18, 2015 - SKZ-U LLP (subsidiary of NAC Kazatomprom JSC) Sulfate plant in Zhanakorgan region of Kyzylordinskaya oblast produced the first million ton of the acid. This is a significant event for the plant with the team which has endeavored its best efforts and has used its qualification to achieve the tasks assigned.The plant was built in December, 2011, under the program “Forced Industrial-Innovative Development of Kazakhstan for 2010-2014». As a feedstock for its products the plant uses Kazakhstan block sulfur supplying Kazatomprom’s enterprises with sulphuric acid which is the basic reagent in the process of uranium production by means of In-situ leaching technique at the mines of Khorassan-1, Khorassan-2, Severnyi and South Karamurun deposits.For manufacturing of sulphuric acid «SKZ-U» LLP uses state-of-the-art, effective and environmentally-friendly technologies – transition of feed into the end product reaches approximately 99,9 %.Besides the plant has used energy-saving production methods. As a result the enterprise can supply itself and regional networks with electric energy up to 18 MW.The design capacity of the plant is 500 000 t of sulphuric acid per year or 1500 t per day. The plant total cost is about USD216 million. «SKZ-U» employs more than 300 people.
July 19, 2012 - A unique enterprise of the KazAtomProm National Company has been launched in the Zhanakorgan district in the Kyzylorda region. It produces sulfuric acid. The plant, the construction of which took three years, began turning out products last week. A special feature of the complex is that it does not produce emissions to the environment. Our capacity is not more than 40%. We will bring it to the design capacity until the end of this month. We produce 1,500 tons of acid daily. Products are dispatched to our customers. The production is based on double conversion technologies. A computerized system controls all the technological processes. Francesco Sama, a starting-up and adjustment specialist from Italy, noted that the plant is environmentally friendly judging by its exhaust pipe, so there are practically no emissions and on the outside it seems that the plant is not working. Currently the plant employs 284 people. Berik Askarov is one of them. Now that the plant appeared in his native village, he was among other local residents who learned a trade under the “2020 Employment” program and is now working for the new plant.
Uraniumone – Management’s Discussion and
Analysis – Year ending December 31, 2010 The Corporation’s SKZ-U
joint venture with Kazatomprom and its other joint venture partners continue
to advance the development of a sulphuric acid plant near Kharasan at
Zhanakorgan. The Corporation’s ownership percentage in SKZ-U is 19%. The
total construction cost of the plant is expected to be approximately $217
million, of which approximately 45% has been funded by the joint venture
partners to date, with the balance funded by the partners through debt
financing. Mechanical completion of the plant is scheduled by the end of
2011 and production of sulphuric acid is expected to commence in 2012. The
Corporation has funded $18 million of its debt obligation to date towards
the construction of the sulphuric acid plant. The balance of approximately
$13 million will be funded in 2011.
Desmet Ballestra and Soyuzcomplect have completed the designs for the
engineering work for the plant. Equipment orders have been placed and
materials and equipment are arriving on site. The turbine has been
manufactured and is ready to be shipped from Europe. In 2010, the general
contractor continued work on the foundation for the cooling towers, storage
and the laboratory building. The foundations for the converter, acid
storage, water and diesel storage are complete. The power generation complex
contractor has completed the foundation for the power generation turbine.
Construction of infrastructure facilities such as the access road, enclosed
warehouse storage, rail spur, temporary camps, power and water supply are
complete. The construction of a water pond is also complete with the piping
to be installed during the plant construction stage.
Capital expenditure incurred during 2010 was $50 million, compared to the
budget of $60 million. The difference was due to delays in the finalization
of the construction contract, delaying the start of construction for the
project. Capital expenditure incurred by SKZ-U in 2011 is expected to be
approximately $111 million on a 100% basis.
SAP-U / SKZ-U SAP-U LLP is
realizing a program for construction of a sulfuric acid plant in the
Zhanakorgan region of the Kyzylorda Oblast with a capacity of 500,000 tonnes
per year or 1,500 tonnes per day.
The start of operation is scheduled for the 4th quarter 2011.
On August 31, 2009, a ceremony of laying a capsule into foundation of the
new sulfuric acid plant took place. The same day infrastructure facilities
of the future plant were put into operation as following: - an access road (IV
category), 9 km long; Founding members of SKZ-U LLP are Mining Company LLP (NAC Kazatomprom’s subsidiary, 49%), SAP-Japan Corporation (Japan - 32%) and Uranium One (Canada – 19%). Primary consumers of SKZ-U LLP will be Khorassan-1 and Khorassan-2 with total production of 5,000 t U per year. The shipment of finished product (93% H2SO4) to be made through the pipeline to the terminal station of Zhanakorgan-transit LLP. All technological processes at the plant will be regulated by a computer controlled system. Production technology Sulfuric acid
production is based on double conversion/double absorption technology under
MECS license. The raw material
for acid production is sulfur, in lumps, obtained from Tengizshevroil LLP
and thus, the project will contribute to the improvement of the Caspian
region environment by sulfur utilization. Unit capacity: One SAP
ancillary product will be electric power generated to the amount of 19.9
megawatt. In its turn this
electric power will be used for the needs of the production facility and
supplied to the general regional electric power grid.
Local units for domestic and industrial sewage treatment, the storm sewer
system and boiler feed water circulation are designed on the territory of
the plant. Thus, from the
output, the plant specialists will have briquette waste and purified water
suitable for irrigation. The
main SAP-U LLP principle is not to do harm to the environment. The LLP is certified for conformity with International
Quality Assurance Standards, environmental protection and labour safety: ISO
9001:2004, ISO 14000:2004 and OHSAS 18000.
It is expected that more than 200 working places will be created at the
Plant, 90% of which will be for local citizens.
Temporary employment for the period of construction (3 years) will be
provided for close to 500 people.
The SAP staff technical training program is planned to be started in 2010.
