Metso Delivers First DRI Smelting Furnace to Eti Bakir

Eti Bakir has awarded Metso a €55 million contract to supply core process technology for the expansion of its Mazidagi integrated fertilizer and metal production site in Türkiye. This project represents the first commercial-scale delivery of Metso’s Direct Reduced Iron (DRI) Smelting Furnace technology. Designed to recover additional value from industrial byproducts, the integrated solution will process leach residue from the site, converting it into molten hot metal alongside marketable iron and slag products to support Eti Bakir's vision of a zero-waste industrial complex.

The scope of delivery encompasses basic and equipment engineering, as well as supply and advisory services. Metso will provide an SL/RN Xtra rotary kiln pellet direct reduction process paired with a 30 MVA Metso Outotec^® DRI Smelting Furnace and a hot feeding system. This investment builds upon a long-standing partnership between the two companies; Metso has previously supplied beneficiation, calcination, off-gas cleaning, sulfuric acid, and metal recovery leaching plants for the Mazidagi complex in Mardin Province.

Additional Context
This section provides technological and market background not explicitly detailed in the original release.

The metals and mining industry faces increasing pressure to minimize hazardous tailings and maximize resource efficiency through circular economy principles. Leach residues, typically treated as waste from hydrometallurgical extraction processes, still contain significant amounts of unrecovered base metals and iron. Metso’s DRI Smelting Furnace represents a critical technological bridge in the effort to decarbonize metallurgical processing. Unlike traditional blast furnaces that require high-grade iron ore and coking coal, the DRI electrical smelting process is highly flexible, enabling the use of lower-grade feedstocks—such as blast furnace-grade iron ores and complex industrial residues—while drastically reducing carbon dioxide emissions,. The SL/RN Xtra rotary kiln efficiently reduces the pelletized waste into direct reduced iron before it is continuously fed—while still hot—into the 30 MVA electric smelting furnace, optimizing overall energy efficiency and ensuring the economical production of high-quality hot metal.
