SELECTING THE BEST QUALITY REFRACTORIES, WHICH HELP INCREASE THE LIFE OF HEAT-CONTAINING INDUSTRIAL VESSELS LINING, IS AN IMPORTANT FACTOR IN IMPROVING PERFORMANCE OF A HIGH-TEMPERATURE PRODUCTION FACILITY. WE KNOW HOW TO ACHIEVE CONSISTENT RESULTS IN THIS AREA, AND OFFER YOU NEW OPPORTUNITIES PROVIDED BY A UNIQUE MAGNESITE DEPOSIT IN SIBERIA.

In 2011, Magnezit Group obtained a license to develop the Talsk magnesite deposit in Razdolinsk (Krasnoyarsk Territory), which is the largest high-quality magnesite deposit on the continent. Together with the neighboring Kirgiteisk deposit, which the company has been developing since 2006, the Talsk magnesite deposit makes up the Group's source of unique magnesite ore in Siberia, with more than 110 million metric tons in known reserves of especially pure crystalline magnesite.
Found in the heart of the Siberian taiga, our magnesite deposits outperform all other known deposits on the continent in terms of qualitative characteristics. The eastern Siberian magnesite is pure and has consistent chemical composition, with MgO loss free content of 98% and above, and a minimum of impurities - silicon, calcium, iron and aluminum oxides.
Since early 2013, magnesite ore has been produced in Razdolinsk on a commercial scale and has become part of the production cycle at the Lower Angara and the Satka production sites, securing a source of unique, high-quality ore for the company for more than 100 years to come.
TODAY’S HIGH-TEMPERATURE PRODUCTION FACILITIES NEED REFRACTORY SOLUTIONS CAPABLE OF WITHSTANDING EVER-MORE-DEMANDING PROCESS MODES. THE QUALITY OF SUCH SOLUTIONS DEPENDS ON THE MAGNESITE ORE THEY ARE BASED ON, AS WELL AS ON THE PROCESSING TECHNOLOGIES. WE MINE UNIQUE MAGNESITE AT OUR OWN LARGE DEPOSIT IN SIBERIA. TO PRESERVE ALL OF THE ORE’S USEFUL PROPERTIES, WE ESTABLISHED A LEADING-EDGE PROCESSING FACILITY.
Over the past few years, Magnezit Group has extensively upgraded its two leading production sites – the Satka site in Chelyabinsk Region and the Lower Angara site in Krasnoyarsk Territory.
In Satka, we have built a state-of-the-art complex for production of dead-burned magnesia clinkers. Created from scratch, it houses the most advanced equipment used in the production process: a multiple-hearth furnace, grinding and briquetting equipment, and two shaft kilns for burning magnesia powder.
The plant’s multiple-hearth furnace has been specifically designed for Magnezit Group by the German company Polysius AG (now ThyssenKrupp Industrial Solutions). At the start-up stage, our experienced engineers set its heat treatment parameters so that they better match the properties of our in-house produced magnesite to ensure the highest quality of magnesia products. An important feature of the furnace is the speed and ease of resetting it for making materials with specific parameters. This enables us to flexibly manage our product range to adapt to customer needs.
The complex’s production cycle also includes a grinding and briquetting shop and two Polysius AG shaft kilns. The largest of them – shaft kiln No. 2 – has set a world record for productivity: used worldwide, such equipment has never before exceeded 50,000 metric tons p.a. in capacity.
After the launch of two Polysius AG shaft kilns at the Lower Angara site in Razdolinsk, the aggregate annual capacity of Magnezit’s equipment of this type reached 230,000 metric tons of magnesia.
All the equipment that has been put in operation complies with the most up-to-date international standards, including those in energy efficiency and environmental safety.
THE UNIQUE SIBERIAN MAGNESITE DEPOSITS AND STATE-OF-THE-ART PROCESSING TECHNOLOGY MAKE IT POSSIBLE TO IMPROVE THE ENTIRE RANGE OF OUR PRODUCTS AND MANUFACTURE NEW HIGH-QUALITY MATERIALS, WHICH WE HAVE CALLED RUSSIAN MAGNEZIT™. WE USE THEM TO MAKE REFRACTORIES WITH THE MOST ADVANCED PERFORMANCE CHARACTERISTICS. THE NEW LEVEL OF PRODUCT QUALITY IS SUPPLEMENTED WITH A WELL-DEVELOPED GLOBAL LOGISTICS, ENGINEERING AND SERVICE NETWORK.

about Russian Magnezit™ and products based on it
by contacting our managers at the following events:
Russian Magnezit™ is a new flagship line of materials for manufacturing high performance refractory products used in heat-containing industrial vessels.
Russian Magnezit™ is fused and dead-burned magnesia with an MgO content of 97% and above, a CaO/SiO2 ratio of at least 2, and a high degree of crystal size consistency.
Today, we use Russian Magnezit™ to make a wide range of refractories. The unique performance characteristics of these raw materials made it possible for us to greatly improve the quality of our refractory products.
