Weir’s sustainable mining flowsheets: HPGR design implications for engineers

August 3, 2026|

Reviewed by Joe Ashwell

First reported on International Mining – News

30 Second Briefing

Weir is pushing “sustainability by design” in comminution and classification, using high‑pressure grinding rolls (HPGRs) and re‑engineered flowsheets to cut energy use and water demand while maintaining throughput. Regional Engineering Director EMEA Christian Stehle points to dry or low‑water circuits, advanced process control and digital twins to optimise mill and crusher performance in real time. For geotechnical and plant engineers, the shift towards HPGR‑centric, coarse‑particle and dry‑stack compatible circuits directly affects tailings design, water balances and plant layout.

Technical Brief

  • Weir is aligning new equipment designs with miners’ ESG reporting frameworks, embedding energy and water KPIs.

Our Take

Weir’s sustainability messaging here aligns with recent coverage of its GEHO pumps for Lloyds Metals’ iron ore slurry pipeline in India, signalling a push to frame high-pressure transport and dewatering equipment as enablers of lower-footprint bulk materials handling rather than just reliability upgrades.

Across our database, Weir appears more often in project-specific items like the Brightstar Resources Goldfields gold plant crushing circuit than in broad ESG features, suggesting this piece is part of a deliberate effort to reposition the company from a component supplier to a technology partner on ‘sustainable mining’ outcomes.

Copper to the World Innovation Hour finalists: throughput and energy notes for mine teams

Six organisations have been shortlisted for the Copper to the World Innovation Hour, where they will pitch live in September to address copper-sector bottlenecks linked to the energy transition, electrification and digital infrastructure. The finalists are developing technologies aimed at improving copper discovery, extraction and processing performance, with a focus on higher throughput, lower unit energy use and reduced environmental footprint across existing operations. For mine planners and metallurgists, the event signals where near-term innovation funding and pilot deployments in copper mining and concentrator circuits are likely to concentrate.
