McLanahan efficiency upgrades: dewatering design notes for brownfield mines
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
McLanahan is promoting compact process solutions such as its recessed-plate filter presses and QUICKCHANGE filter cloth system to lift plant efficiency and reduce tailings water loss in existing mines. The QUICKCHANGE design allows individual cloths to be swapped without removing the plate pack, cutting press downtime, manual handling and confined-space exposure during maintenance. For brownfield operations constrained by legacy footprints and power limits, the company is positioning modular dewatering and screening units as bolt-on upgrades rather than full plant rebuilds.
Technical Brief
- QUICKCHANGE’s plate-mounted cloths eliminate full plate-pack extraction, reducing time spent in pinch-point zones.
- Individual cloth replacement reduces manual lifting of heavy plate stacks, directly lowering musculoskeletal injury exposure.
- Maintenance tasks move from confined press interiors to open access areas, simplifying lock-out/tag-out implementation.
- Shorter intervention windows reduce cumulative exposure to high-pressure hydraulics and residual slurry spray.
- Standardised cloth attachment hardware supports repeatable change-out procedures and clearer task-specific training.
- Retrofit-friendly press modules allow safety upgrades on legacy plants without major structural or electrical rework.
- Reduced need for mobile lifting equipment around presses cuts interaction risks between personnel and moving plant.
- Similar modular retrofits could help older mining sites align with contemporary isolation and access standards.
Our Take
Within our 415 Mining stories, Australia-linked pieces with Product and Safety tags often focus on plant optimisation and operator protection, so McLanahan’s positioning here likely targets brownfield upgrades rather than greenfield mega-projects.
Across the 843 tag-matched pieces, suppliers that frame equipment around both efficiency and sustainability tend to gain traction in tendering for Australian mines facing tighter water, tailings and energy performance expectations.
In the subset of keyword-matched pieces referencing AI or artificial intelligence, most mining product coverage involves smarter monitoring and control layers on conventional kit, suggesting McLanahan’s Australian offering may need clear digital or data hooks to stay competitive in this space.
