01 / COMPANY
Baltic resources.
International scale.
Kaliningrad Potash Company LLC has been developing the Poddubnoye potassium-magnesium salt deposit project in Russia’s Kaliningrad Region since 2016. The company is developing an integrated mining and processing complex, from extraction to advanced processing of natural salts.
The project envisages Russia’s first production of sulfate of potash (SOP) from natural raw materials. Potassium magnesium sulfate and magnesium sulfate are also planned. The complex will combine the region’s mineral resources with Kaliningrad’s year-round maritime logistics.
02 / PODDUBNOYE DEPOSIT
A substantial resource.
A long-term outlook.
Located south of Kaliningrad, the deposit is the foundation of the future industrial complex.
Project at the pre-construction stageResource base3.1 billion tonnes
The State Commission on Mineral Reserves (GKZ) has recorded 3.1 billion tonnes of crude salt reserves in categories C₁ + C₂ on the Russian State Balance of Mineral Reserves.
Expansion potentialUp to 1.5 million t/year of SOP
Potential to expand the base design capacity of 1.03 million tonnes per year.
LogisticsAccess to the Baltic Sea
Proximity to port, rail and power infrastructure in the Kaliningrad Region.

Project objectiveTHE PROJECT’S MAIN PRODUCTSOP
K₂SO₄
Sulfate of Potash
Potassium sulfate
03 / PRODUCT
Potassium and sulfur.
In one fertilizer.
Sulfate of potash is a chloride-free potassium fertilizer for effective plant nutrition.
01
For chloride-sensitive crops
Suitable for fruit, vegetables, berries and other crops sensitive to chloride.
02
For modern crop nutrition
The project targets water-soluble SOP, including for fertigation — the application of fertilizer through irrigation water.
03
For international markets
Planned output is primarily intended for export and long-term customer partnerships.
PLANNED PRODUCT PORTFOLIO
1.58 million tonnes
of saleable products per year.
Planned total capacity of the complex. Sulfate of potash is the main product, complemented by potassium magnesium sulfate and magnesium sulfate.
Sulfate of potash · SOP
Approximately 1.03 million tonnes per year in the base design, with potential to expand SOP production to 1.5 million tonnes per year.
Potassium magnesium sulfate and magnesium sulfate
Planned saleable products from the advanced processing of potassium-magnesium raw materials.
PROJECT SIGNIFICANCE
A new centre of industrial growth
in the Kaliningrad Region.
Mineral resource independence
Developing domestic processing of natural salts and import substitution in chloride-free potassium fertilizers.
Value-added exports
Producing value-added products for international markets, supported by Baltic maritime logistics.
Regional development
Creating jobs, developing industrial and transport infrastructure, and increasing tax revenues.
