May 27, 2026 - The Company has put into operation a sulfuric acid production plant in the Zhambyl Region of the Republic of Kazakhstan. The facility ranks among the largest of its kind in the country with an annual design capacity of 800,000 tonnes. The plant’s products will be used both for the EuroChem’s chemical complex under construction and to meet the needs of the domestic market in Kazakhstan.  The launch of the plant is Phase II of EuroChem’s large-scale investment project in Kazakhstan. In Phase I, the Company launched a phosphate ore mining and processing complex with an annual capacity of 840,000 tonnes. The final Phase III will be the launch in 2027 of a chemical complex for the production of mineral fertilizers and industrial products. Total investments exceed $1 billion, while total annual output upon completion of all Phases will be more than 1 million tonnes.  The project is being implemented under the Unified Industrialization Map of Kazakhstan.

"The project is fully aligned with the strategic goals set by the President of the Republic of Kazakhstan to develop the manufacturing industry, diversify the economy and ensure the country’s economic self-sufficiency. The launch of high-tech production facilities serves as a prime example of strengthened industrial cooperation and strategic partnership between our nations. I am confident that once the project reaches it’s full capacity, it will make a substantial contribution to the economic development of Kazakhstan", (Yersaiyn Nagaspayev Minister of Industry and Construction of the Republic of Kazakhstan)

 

Following the completion of all Phases, the Zhambyl Region will have one of the few full-cycle chemical production facilities in the world, where raw material extraction, processing and production of finished goods are integrated into a single production chain.  The complex’s products will be in demand not only in Kazakhstan but also across other countries in Central Asia, China and European markets. 

 

"The project implements state-of-the-art high-tech solutions that guarantee quality and safety. EuroChem intends to continue investing in the development of its production facilities and strengthening its partnership with the agro-industrial complex of Kazakhstan" (Igor Georgiadi CEO of EuroChem Karatau)

 

The project is significantly important for the social and economic development of the region. Total tax revenues to the budget of Kazakhstan have already reached approximately 70 billion tenge during the implementation of the project. Upon completion of all Phases, over 1,200 jobs will be created within the Company, with at least an equal number in related service and logistics organizations. Since 2012, EuroChem has invested approximately $29 million in the development of social infrastructure of the Zhambyl Region, including renovations of residential buildings, schools, healthcare facilities and urban infrastructure.


May 26, 2026 - A ceremony was held at the EuroChem-Karatau production site in the Sarysu district of the Zhambyl region to mark the launch of a sulfuric acid plant with a capacity of 800,000 tons per year. This event marked the completion of the first stage of the second phase of one of Kazakhstan's largest industrial projects, with a total investment of up to $1 billion. The project is being implemented with the assistance of KAZAKH INVEST NC JSC.  The ceremony was attended by Yerbol Karashukeyev, Akim of the Zhambyl Region; Yersaiyn Nagaspayev, Minister of Industry and Construction of the Republic of Kazakhstan; Nurgazy Anuarbek, Managing Director of KAZAKH INVEST NC; Igor Akhmerov, General Director of EuroChem PMU LLC; Igor Georgiadi, General Director of EuroChem-Karatau LLC; and representatives of government agencies, the business community, and international organizations.  The project's history spans nearly two decades. Initiated in 2008, it has evolved from the initial geological surveys to a fully-fledged chemical production facility. Development of the Karatau phosphorite deposit began in 2012, and the mining plant—the first stage of the project — was commissioned in 2016. The intergovernmental agreement on the implementation of the second stage was ratified by the President of the Republic of Kazakhstan in January 2022, after which construction of the chemical plant immediately began. Today's launch of the sulfuric acid production facility is the first stage of this large-scale project. The general EPC contractor was CNCEC, a leading Chinese engineering company specializing in chemical projects.  A distinctive feature of the project is the use of environmentally friendly technologies. Unlike traditional phosphorus production, which produces phosphogypsum, EuroChem's technology involves the production of calcium chloride and synthetic gypsum — products in demand in construction, the agro-industrial complex, and other sectors of the economy  Construction and installation work for the second stage of the plant is underway at all production facilities and is 72% complete. Commissioning is scheduled for the first quarter of 2027. Once fully operational, the plant will produce up to 1 million tons of products annually, including dicalcium phosphate (200,000 tons), potassium sulfate (260,000 tons), calcium chloride (130,000 tons), and synthetic gypsum (320,000 tons).  The project's implementation is having a significant impact on the socioeconomic development of the Zhambyl region. EuroChem currently employs over 1,000 people, with service and outsourcing companies providing approximately 300 additional jobs. Up to 2,000 people are currently involved in the active construction phase. Once the complex is fully operational, at least 1,200 new permanent jobs will be created.  By the end of 2025, phosphate production volume will reach 890,000 tons, valued at 17 billion tenge, and in the first four months of 2026, approximately 345,000 tons of the product will be produced, valued at 8 billion tenge. 

November 27, 2024
- EuroChem Karatau, a subsidiary of the Russian EuroChem, plans to launch a fertilizer manufacturing facility in the Zhambyl region in February 2027.  According to a statement published by the company, the approximate timeline for the project is 24 months. Construction is expected to start in the first quarter (March) of 2025 and finish in the first quarter (February) of 2027.  Once completed, the plant will operate until 2052-2053, when its equipment will have to be replaced. The fertilizer manufacturing plant will consist of a sulfuric acid plant (SAP Plant) with a capacity of 800,000 tons per year, a potassium sulfate production facility (SOP Plant) with a capacity of 260,000 tons per year, a calcium hydrogen phosphate plant (DCP Plant) with a capacity of 200,000 tons per year, and a calcium chloride facility (CaCl2 Plant) with a capacity of 130,000 tons per year.  The plant is expected to be launched in two stages. The first stage, which is the SOP Plant, should be commissioned at the end of 2025, while the second phase — fertilizer production — will be launched in 2027.About half of the 800,000 tons of sulfuric acid will be supplied to Kazatomprom, as the company uses sulfuric acid for solvent extraction of uranium. The fertilizer plant will use Kazakhstan-produced gas for its production process. According to the CEO of EuroChem Karatau Igor Georgiadi, the production facility will need 130 million cubic meters of gas annually if it operates at full capacity.The future plant will be built 14 kilometers southwest of Zhanatas, the center of the Sarysu district of the Zhambyl region. Once commissioned, it will produce 33 tons of potassium sulfate, 16.25 tons of calcium chloride and 25 tons of calcium hydrogen phosphate per hour. Moreover, the plant will also produce 249.2 tons of 15% calcium chloride brine (CaCl2) per hour and 45.1 tons of gypsum (CaSO4) per hour as byproducts.For the production of potassium sulfate, the company will build 28 specially designed furnaces using phosphate ore from the Kok-John (Araltobe and Kesiktobe sections) and Gimmelfarb fields, controlled by EuroChem Fertilizers (part of EuroChem), as raw materials. EuroChem Karatau produces ground rock phosphate on its own, while potassium chloride (218,400 tons), limestone (230,000 tons) and block sulfur (275,000 tons) will be sourced from third-party producers.  To facilitate production, EuroChem Karatau is going to reconstruct several railways at the Rudnichnaya railway station in the Zhambyl region, 18 kilometers southwest of Zhanatas.EuroChem is one of the largest global producers of fertilizers, with production capacities in three key groups of fertilizers: phosphoreal, potassium and nitrogen-based chemical fertilizers. Over the past ten years, the company has invested more than $11 billion in the development of its production facilities. Key assets of EuroChem are located in Russia.  The company was established in 2001 by Russian businessman Andrey Melnichenko. He used to be the key beneficiary of the company until he was added to the European sanctions list in March 2022. According to Forbes, Melnichenko and his family are ranked 108th in the global ranking of the richest people (and seventh in the Russian ranking) with a fortune of $17.7 billion.
