Sandvik Completes Diemme Filtration Acquisition to Strengthen Mining Value Chain

Industry Milestone: Sandvik Enters Filtration and Dewatering Segment

Sandvik has completed the previously announced acquisition of Diemme® Filtration, an Italy-based leading provider of filtration and dewatering solutions for the global mining industry. The company will be reported as a separate new division, Filtration, within business area Rock Processing. Diemme is headquartered in Lugo, Italy, with a state-of-the-art manufacturing facility and R&D capabilities, approximately 200 employees, and a diversified global customer base across copper, gold, nickel, and battery-materials mining. Revenues for 2026 are estimated to be about SEK 1.1 billion, with an EBITA margin accretive to business area Rock Processing. This acquisition marks Sandvik‘s strategic entry into the filtration and dewatering segment, strengthening its offering across the mining value chain. While such vertical integration represents a significant strategic move by a global industry leader, OCP Mechanical Company recognises that not every operation requires the scale or investment associated with these comprehensive solutions. With over 40 years of manufacturing experience, we offer practical, cost-effective crushing solutions tailored to medium-capacity operations, backed by factory-direct pricing and round-the-clock technical support.

Diemme Filtration: Proven Technology for Tailings Management and Water Recovery

Diemme Filtration brings to Sandvik a portfolio of high-performance filter presses with demonstrated results in demanding mining applications. The company‘s GHT series filter presses are specifically engineered for the treatment of concentrates and mineral tailings, with a design emphasis on high throughput and reliable operation. In a major tailings filtration project in Minas Gerais, Brazil—a key region for iron ore production—Diemme supplied four GHT 2500 F26 filter presses with supporting equipment, achieving a processing capacity of 672 tonnes per hour of dry solids and producing a filtered cake with moisture content of up to 15% . A separate project involving three GHT2500F filter presses similarly achieved the highest level of dewatering of copper tailings slurry, significantly reducing the environmental and social impact of the mining process. These results demonstrate how advanced filtration technology can transform tailings management from a liability into a managed, compliant operation. For mining companies facing increasingly stringent regulations on tailings storage and water usage, Diemme’s proven capabilities represent a meaningful addition to Sandvik‘s offering.

Strategic Rationale: Why Filtration Matters for Modern Mining

Sandvik‘s decision to acquire Diemme reflects a broader recognition that filtration is a critical process step in downstream mining. Demand for filtration technologies is being driven by declining ore grades, which increase slurry volumes and the need for greater filtration capacity. At the same time, mining companies face mounting pressure to reduce water consumption, improve tailings safety, and comply with stricter environmental regulations. The global mining dewatering filter press market is projected to grow from approximately USD 472 million in 2025 to USD 629 million by 2032, at a compound annual growth rate of 4.3% . The filtration business that Diemme operates in is growing at around 15% per year, significantly faster than the broader mining equipment market. By establishing a dedicated Filtration division within Rock Processing, Sandvik is positioning itself to capture this growth while offering customers a more complete flowsheet solution—from primary crushing through to final tailings management. This integration aligns with the industry‘s growing preference for suppliers who can take responsibility for multiple process stages, reducing interface risk and simplifying project delivery.

From Crushing to Dewatering: The Case for Integrated Flowsheet Design

The Sandvik-Diemme combination highlights a fundamental truth about modern mineral processing: the crushing circuit and the dewatering circuit are not independent systems. The particle size distribution produced by the crushing and grinding stages directly determines the performance of downstream filtration equipment. Coarser, more uniform feed to the filter press results in faster cycle times, lower moisture content, and higher throughput. Conversely, excessive fines generation in the crushing circuit—often caused by over-crushing or inappropriate crusher selection—can choke the filtration stage and reduce overall plant efficiency. For quarry operators and mining companies, this interdependence means that equipment selection decisions must be made with the entire flowsheet in mind. A crusher that delivers excellent throughput but produces an unfavourable particle size distribution for downstream processing is not a good investment. Similarly, filtration equipment that cannot handle the fines content in the slurry will underperform regardless of its nominal capacity. OCP Mechanical Company, with over 40 years of manufacturing experience, understands this interdependence. Our jaw crushers, cone crushers, impact crushers, and VSI crushers are engineered to deliver the consistent, well-graded product that optimises both downstream grinding and dewatering performance. Our engineering team works closely with each customer to design custom crushing plants that match specific site conditions, feed characteristics, and production targets—ensuring every component is matched to the others to prevent bottlenecks and maximise overall plant efficiency.

What This Means for Equipment Buyers in the Mining Sector

For mining companies evaluating equipment investments, the Sandvik-Diemme acquisition carries several practical implications. First, the consolidation trend in the mining equipment sector continues, with major suppliers expanding their portfolios to cover more of the value chain. This creates opportunities for buyers to source more equipment and services from fewer suppliers, simplifying procurement and project management. Second, the increasing focus on tailings management and water recovery means that filtration performance will become an increasingly important criterion in crusher selection. Operators should consider how their crushing circuit affects downstream dewatering efficiency, not just how it performs in isolation. Third, while integrated flowsheet solutions offer clear advantages for large-scale, capital-intensive projects, they are not the only path to efficient operation. Many mid-tier operations achieve excellent results with carefully selected equipment from specialist manufacturers, configured to work together seamlessly. OCP Mechanical Company serves this segment with jaw crushers, cone crushers, impact crushers, VSI crushers, vibrating screens, feeders, and complete crushing and screening plants engineered for durability and efficiency. As a direct factory manufacturer, we eliminate distributor margins, passing the savings directly to you—a significant advantage when every dollar of capital expenditure must be justified.
