High-Pressure Slurry Ablation — chemical-free liberation that helps you optimise the operation you already run, recovering more value from every tonne. Brought to your region by Optimise Minerals.
HPSA changes how comminution energy is applied — targeting liberation rather than indiscriminate size reduction. The result is measured where it counts: in the valuable mineral you recover and sell.
Cleaner liberation at coarser grind sizes means more of the target mineral reports to concentrate instead of being lost to tailings.
More metal per tonne of oreModular skids integrate into existing circuits in weeks, lifting the volume of saleable product across the same plant and overheads.
More output, same footprintWhen recovery and concentrate quality rise together, the cost to produce each tonne of valuable mineral falls — the number that drives project economics.
Lower cost per tonne of productHPSA directs opposing high-velocity slurry jets to create particle-to-particle collisions that fracture ore along its natural grain boundaries and hardness differentials — releasing target minerals early, at coarser grind sizes, with reduced fines.
Across more than 150 ore campaigns, HPSA consistently improves grade and recovery at coarser grind sizes. The figures below are drawn from DISA's published copper-sulfide results.
Performance is ore-specific and confirmed through laboratory characterisation and pilot testing on your material. Improved flotation kinetics accompany the grade and recovery gains shown above. Further commodity results are detailed on the Applications page.
Proven on sulfides, oxides, industrial minerals and tailings retreatment — upstream, midstream or downstream, adding liberation where it matters most.
Optimise Minerals is the appointed sales agent for DISA Technologies' HPSA across Europe, the Middle East, Africa and Central Asia. We bring the technology to your operation — from first technical conversation through testing, integration planning and commissioning support.
HPSA has commercial installations in North America, with independent third-party verification. A European laboratory partnership for regional testing is in progress.
Every deployment starts with your material. Tell us about your circuit and the value you're chasing, and we'll map a testing and integration pathway.
