ONE TECHNOLOGY. MULTIPLE PATHWAYS TO VALUE.
DISA Tech™ delivers scalable solutions that enhance recovery, streamline operations, and transform legacy materials into productive assets—across mining, remediation, and beyond.
MINERAL PROCESSING
MINERAL PROCESSING
Advanced mechanical liberation that improves recovery, reduces cost, and integrates seamlessly into existing operations.
Unlock higher recovery—without increasing grind intensity.
Integrate advanced liberation into your existing circuit—no rebuild required.
Improve throughput, energy efficiency and payable metal output with a fully mechanical process.
HPSA TECHNOLOGY IN ACTION
See how HPSA™ technology enhances liberation, improves recovery, and integrates seamlessly into an operating plant.
Every circuit is a balance of recovery, cost, and operational risk. HPSA technology improves that balance.
The HPSA platform enhances selective liberation at coarser grind sizes—reducing overgrinding, lowering energy use, and improving downstream recovery. By targeting mineral boundaries instead of indiscriminately shrinking particles, HPSA units increase concentrate grade while minimizing excess fines and reagent demand.
Measurable Impact
Increased recovery and payable metal output
Reduced energy intensity and wear costs
Greater flexibility with variable feed
Modular integration with minimal disruption
HPSA units are skid-mounted and plug-and-play—installed in weeks, not months—allowing operators to validate performance without major capital rebuilds.
Seamless Circuit Integration
HPSA units can be deployed:
Ahead of flotation to enhance liberation
As a lower-energy regrind alternative
In tailings retreatment applications
For complex or challenging ore bodies
Our team works directly with site engineers to evaluate placement, model uplift and quantify impact before deployment.

TAILINGS
RECOVER VALUE. IMPROVE STABILITY. REDUCE WASTE.
Tailings often contain recoverable value due to incomplete liberation in legacy circuits. HPSA technology provides a modular, mechanical pathway to unlock that value—without overgrinding or major infrastructure changes.
HPSA Technology for Tailings
— Selective mechanical liberation to unlock residual mineral value
— Improved grade and recovery without excessive fines generation
— Coarser, more stable tailings enable innovative disposal methods and faster water recovery
— Lower energy and wear than conventional regrind systems
— Direct integration into existing tailings streams
— Skid-mounted, modular deployment with minimal site modification
In partnership with Regeneration and ElementUSA, HPSA technology is applied to reprocess tailings and unlock residual value.
TESTING & VALIDATION
FROM BENCH SCALE TO COMMERCIAL DEPLOYMENT
Every site is different. Every ore body behaves differently. Every remediation project carries unique constraints. DISA maintains comprehensive in-house testing and analytical capabilities to evaluate material characteristics, optimize HPSA deployment, and quantify performance improvements before field integration.
