Sandvik acquires Diemme® Filtration to expand mining solutions, strengthen filtration capabilities, boost aftermarket growth, and enhance sustainable mineral processing.
Sandvik has announced the signing of an agreement to acquire Diemme® Filtration, an Italy-based company recognized globally for its advanced filtration and dewatering technologies serving the mining sector. The acquisition represents a significant strategic step for Sandvik as it broadens its presence within the mineral processing value chain. Following the completion of the transaction, Diemme® Filtration will operate as a newly established division named Filtration within Sandvik’s Rock Processing business area.
The move marks Sandvik’s entry into the filtration and dewatering market, a segment considered essential to modern mining operations. By incorporating Diemme® Filtration’s expertise and product portfolio, Sandvik aims to strengthen its downstream mining capabilities and provide customers with a more comprehensive suite of solutions. The filtration and dewatering market currently represents a total addressable opportunity exceeding SEK 20 billion, highlighting its strategic importance and growth potential.
Diemme® Filtration is particularly known for its strong position in the high-performance filter press segment. The company’s technologies play a crucial role in solid-liquid separation processes, helping mining operators improve operational efficiency, enhance water recovery rates, and optimize tailings management practices. As sustainability and resource efficiency become increasingly important priorities for mining companies worldwide, these solutions are expected to generate substantial value for customers.
In addition to supplying customized filtration systems engineered to meet specific customer requirements, Diemme® Filtration has built a substantial aftermarket business that offers considerable future growth opportunities. The company also provides proprietary digital solutions, including remote monitoring and predictive maintenance software, enabling customers to maximize equipment performance while reducing downtime. These digital capabilities align closely with Sandvik Rock Processing’s existing technology portfolio and strengthen its broader digitalization strategy.
Commenting on the acquisition, Sandvik President and CEO Stefan Widing emphasized that the transaction is fully aligned with the company’s strategy of expanding into attractive niche markets within downstream mining. He noted that Diemme® Filtration brings a profitable and rapidly growing mineral-processing business to Sandvik’s portfolio while also strengthening relationships with key mining customers and enhancing recurring aftermarket revenue opportunities.
The filtration market is expected to experience strong growth in the coming years, driven by several structural industry trends. Declining ore grades across many mining regions are resulting in increased slurry volumes, thereby raising demand for advanced filtration capacity. At the same time, stricter environmental regulations regarding water usage and tailings disposal are encouraging mining companies to adopt technologies that support water conservation and the production of denser tailings. These trends are expected to contribute to low double-digit annual growth rates within the filtration segment.
Richard Harris, President of Sandvik Rock Processing, stated that Diemme® Filtration’s product offering complements the company’s existing portfolio exceptionally well. He highlighted that filtration technology is becoming increasingly important in future mining process flowsheets and supports Sandvik’s objective of delivering eco-efficient rock processing solutions. Furthermore, Sandvik expects to leverage its extensive global service network to increase aftermarket penetration and create additional value for customers.
Headquartered in Lugo, Italy, Diemme® Filtration operates a modern manufacturing facility supported by advanced research and development capabilities. The company employs approximately 200 people and serves a diversified international customer base spanning copper, gold, nickel, and battery-material mining sectors. For 2026, Diemme® Filtration is expected to generate revenues of approximately SEK 1.1 billion, with an EBITA margin that is anticipated to enhance the profitability profile of Sandvik’s Rock Processing division.
Financially, the acquisition is projected to deliver returns consistent with Sandvik’s cost of capital within three years of completion and exceed those levels thereafter. Although the purchase price has not been disclosed, Sandvik expects the transaction to have a positive impact on earnings per share, excluding purchase price allocation effects. The acquisition is scheduled to be finalized during the third quarter of 2026, subject to customary closing conditions.
Market Impact: The acquisition of Diemme® Filtration by Sandvik is expected to have a positive long-term impact on the mining equipment and mineral processing sectors, particularly in filtration, dewatering, and tailings management technologies. By integrating Diemme® Filtration’s advanced filter press solutions into its portfolio, Sandvik strengthens its ability to offer end-to-end mineral processing systems, improving operational efficiency, water recovery, and environmental compliance for mining companies. This could accelerate investments in downstream mining infrastructure, especially across copper, nickel, gold, and battery-material projects.
From a commodities perspective, the transaction is unlikely to have an immediate direct impact on chemical prices tracked by ChemAnalyst. However, over the medium to long term, enhanced filtration and dewatering capabilities may improve productivity and recovery rates in mines producing critical minerals used in chemical and battery supply chains. Increased availability of copper, nickel, lithium-bearing materials, and other battery metals could support stable raw material supplies for downstream chemical manufacturers.
For chemical commodities linked to battery materials and mining inputs, the development may exert a mildly bearish influence on prices over time by improving production efficiencies and reducing operational bottlenecks. Additionally, better water management and tailings processing could lower production costs at mining sites, potentially easing cost pressures across related value chains. Overall, the impact on chemical commodity prices is expected to be indirect, gradual, and supportive of long-term supply stability rather than causing any immediate market disruption.
