    Sandvik–Diemme Filtration deal: integrated dewatering flowsheets for mine designers

    First reported on International Mining – News

    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.

    PLS Pilgangoora 22-sorter TOMRA contract: process design notes for engineers

    TOMRA Mining has secured a contract from Pilgangoora Operations Pty Ltd, a PLS Group subsidiary, to supply 22 sensor-based ore sorters for the P2000 Expansion Project at the Pilgangoora lithium operation in Western Australia. The installation is part of PLS’ pre-Final Investment Decision early works, signalling commitment to large-scale sorting ahead of full project sanction. For process engineers, the move points to increased reliance on front-end sensor-based separation to upgrade run-of-mine feed and manage lithia grade variability before downstream concentration.

    Macmahon’s 42‑month Telfer Gold Mine extension: planning notes for project teams

    Macmahon Contractors has secured a 42‑month extension to provide contract mining services at Greatland Resources’ Telfer Gold Mine in Western Australia, valued at A$485 million over the term. The deal locks in a multi‑year mining services pipeline at one of the state’s major gold operations, supporting continuity of fleet deployment, workforce planning and site-based maintenance. Contractors and suppliers can expect sustained demand for open-pit and underground support services, consumables and rebuilds tied to Telfer’s existing mine plan.

    Metso–Valmet Flowrox pump deal: slurry circuit implications for mine engineers

    Metso has agreed to acquire Valmet’s Flowrox™ peristaltic hose pump and progressive cavity pump technologies, including associated spare parts and service capabilities, targeting abrasive and chemically aggressive slurry duties in mining and minerals processing. The deal adds positive displacement options alongside Metso’s existing slurry and submersible pump lines, enabling tighter process control in applications such as thickener underflow, filter feed and reagent dosing. For operators, the integration should simplify lifecycle support and parts standardisation across critical slurry handling circuits.
