Sandvik has signed a deal to acquire Italy-based Diemme Filtration, a leading provider of filtration and dewatering solutions for the global mining industry, in a move that expands its footprint deeper into downstream mineral processing.

 

The company will be integrated as a new standalone division, Filtration, within Sandvik’s Rock Processing business area, marking Sandvik’s entry into the filtration and dewatering segment. The acquisition strengthens its position across the mining value chain in a market estimated to exceed SEK 20 billion.

 

Filtration plays a critical role in downstream mining, and Diemme Filtration’s solid-liquid separation technologies are expected to enhance productivity, improve water recovery, and support tailings management—areas increasingly under pressure from both operational and environmental demands.

 

Beyond engineered-to-order systems, Diemme Filtration brings a sizeable aftermarket business with strong growth potential, alongside proprietary software for remote monitoring and predictive maintenance that complements Sandvik’s digital offering.

 

"I am very pleased with this acquisition, which is strongly aligned with our strategy to grow in attractive niches in downstream mining. With Diemme Filtration we add a profitable and fast-growing niche within mineral processing to our core offering, that strengthens our position with key mining customer groups and brings an attractive aftermarket business," says Stefan Widing, President and CEO of Sandvik.

 

Demand in filtration is being lifted by structural shifts in mining. Declining ore grades are increasing slurry volumes and driving the need for higher filtration capacity, while stricter water and tailings regulations are accelerating demand for water-efficient solutions and denser tailings management systems.

 

“Diemme Filtration’s offering is highly complementary to Rock Processing and gives us a strong position in a segment that is central to mining customers’ future flowsheets. It directly supports our strategy for eco-efficient rock processing and brings an opportunity to increase aftermarket penetration by leveraging Sandvik’s global service footprint,” says Richard Harris, President of Rock Processing.
