30 Second Briefing
Sandvik has agreed to acquire Italy-based Diemme Filtration, adding high-performance mining filter presses and dewatering systems as a new Filtration division within its Rock Processing business area. Diemme’s portfolio includes large automated filter presses for tailings and concentrate dewatering, targeting dry-stack tailings and reduced process water consumption in large concentrators. The move gives Sandvik an in-house solution for integrating crushing, screening and filtration flowsheets, with potential implications for tailings storage design and water balance in brownfield and greenfield plants.
Technical Brief
- Diemme Filtration brings established global reference base in mining concentrate and tailings dewatering plants.
- Diemme’s installed base offers Sandvik immediate aftermarket access for spares, cloths, plates and service contracts.
- Brownfield concentrators gain a single OEM interface for debottlenecking around crushing–screening–dewatering constraints.
- For greenfield projects, OEM-level filtration input at DFS stage can materially influence TSF footprint and CAPEX split.
Our Take
Recent coverage of Sandvik’s long-life Leopard DI650i rigs and large underground fleets at Bellevue Gold shows strong penetration in high‑productivity, tech‑heavy operations; adding Diemme Filtration gives Sandvik a stronger pitch to the same clients looking to tighten water balance and tailings footprint at new projects.
Because Diemme Filtration is Italy‑based, this M&A move also deepens Sandvik’s European manufacturing and technology base at a time when OEMs supplying dewatering and tailings solutions are under pressure from EU‑level ESG and circular‑water regulations.
