SELECTIVE LIBERATION,
DELIVERED.

EXPLORE
Our Patented Technology

HPSA™ technology is a patented, modular mineral liberation platform that uses high-velocity slurry collisions to selectively separate target minerals from host material. Operating without grinding media or chemical reagents, HPSA units improve recovery, reduce energy intensity, and unlock value across active mineral processing circuits.

MINERAL PROCESSING

BUILT FOR COMPLEX ORES AND MODERN CIRCUITS.

HPSA units integrate at multiple points across the mineral processing flowsheet—from upstream liberation to midstream regrind and downstream tailings retreatment. Engineered for flexibility, the platform adapts to a wide range of ore types, particle sizes, and process conditions.

HPSA technology has been tested across 150+ ore campaigns, demonstrating versatility across a broad range of mineral systems and processing conditions.

HOW IT WORKS

ENGINEERED FOR SELECTIVE LIBERATION

The HPSA platform replaces indiscriminate grinding with controlled, mechanical particle-to-particle collisions—liberating target minerals efficiently while preserving circuit performance.

From Feed to Liberation


Feed Preparation

Ore slurry is conditioned to a controlled solids concentration and flow rate, preparing material for selective breakage within the HPSA chamber.

High-Pressure Collision

Opposing slurry jets generate particle-to-particle collisions inside the collision chamber. Mechanical energy fractures material along grain boundaries and hardness contrasts.

Selective Liberation

Liberated minerals report to their appropriate downstream processes—flotation, leaching, magnetic, gravity, or sizing—at coarser grind sizes with reduced fines generation.

01: Feed Preparation
02: High-Pressure Collision
03: Selective Liberation

100% Mechanical Process

HPSA units operate without grinding media or chemical reagents, using controlled high-pressure slurry collisions to drive mineral liberation.

Coarser Grind Liberation

Liberates target minerals at larger particle sizes, reducing overgrinding and minimizing the generation of fines and slimes.

Hardness-Driven Selective Breakage

Fractures material along Mohs hardness differentials and natural grain boundaries, enabling preferential liberation of valuable minerals from gangue.

Cleaner Size Distribution

Produces a more controlled particle size profile, improving downstream liberation efficiency and concentrate quality.

Flowsheet Compatible

Integrates seamlessly with flotation, leaching, sizing, magnetic liberation, and gravity circuits—either replacing or supplementing legacy grinding stages.

THE RESULTS

MEASURABLE IMPACT

Energy
& Wear Efficiency

Operates at 3–10 kWh per ton with wear costs below $2 per ton—reducing energy intensity and consumable exposure relative to conventional grinding systems.

Recovery
& Revenue Performance

Selective liberation at coarser grind sizes improves downstream recovery and concentrate grade—directly increasing payable metal output while reducing reagent demand and excess processing stages.

Rapid
Integration

Skid-mounted, modular units are engineered for installation in weeks rather than months, minimizing circuit disruption and accelerating time to value.
