High-Pressure Slurry Ablation Case Studies
Real-world examples showing how HPSA delivers measurable improvements in grade, recovery, energy efficiency, and tailings reprocessing across multiple commodities.
Proven Performance Across Commodities
HPSA has been trialled across a wide range of ores, tailings, and operating conditions, consistently demonstrating higher liberation at lower energy input. These case studies show real project outcomes, including improvements in feed quality, downstream circuit performance, and the recovery of value from waste streams.
Each example highlights the measurable gains HPSA can deliver in both greenfield and brownfield processing environments.
Where HPSA Delivers Value
Applications across mineral processing, remediation, and tailings recovery.
Mineral Processing & Plant Operations
HPSA provides an efficient liberation step for a wide range of ores. It breaks composite particles along natural grain boundaries, improving recovery and reducing the load on energy-intensive grinding circuits. It is suitable for both new plants and retrofit applications.
Remediation & Waste Treatment
HPSA mechanically separates contaminants from soil, waste rock, and legacy materials without chemicals. This supports environmental remediation, heavy-metal removal, and the reclassification or reuse of processed material.
Tailings, Filter Sand & Reprocessing
HPSA upgrades tailings, filter sand, and other low-grade or discarded materials by generating cleaner feed and concentrating valuable fractions. This enables recovery of residual metals, better downstream performance, or reuse of cleaned outputs.

Independent Reports
Testing & Sample Evaluation Services
HPSA testing can be performed on your specific material through a structured laboratory program. Samples are characterised, conditioned in the HPSA unit, and analysed to quantify liberation improvements, particle size reductions, and energy efficiency compared to conventional approaches.
The resulting data package provides clear guidance on performance expectations, circuit integration options, and the viability of scaling HPSA for site-specific applications.
