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 IN ACTION

See how HPSA™ enhances liberation, improves recovery, and integrates seamlessly into an operating plant.

Every circuit is a balance of recovery, cost, and operational risk. HPSA® improves that balance.

DISA’s High-Pressure Slurry Ablation (HPSA) 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 increases 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 is skid-mounted and plug-and-play—installed in weeks, not months—allowing operators to validate performance without major capital rebuilds.

Seamless Circuit Integration

HPSA 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.

REMEDIATION & RECOVERY

RESTORING LEGACY SITES.
RECOVERING STRATEGIC MATERIALS

Abandoned uranium mine (AUM) waste represents both an environmental liability and a strategic opportunity.

DISA’s High-Pressure Slurry Ablation (HPSA) delivers a field-deployable, fully mechanical solution that reduces contamination while recovering uranium already mined and above ground.

Reduce contamination and stabilize legacy waste.

Strengthen American energy security without new ground disturbance.

Recover usable domestic feedstock.

HPSA provides a mechanical pathway to remediate these materials while recovering uranium suitable for reintroduction into the domestic nuclear fuel cycle. Unlike chemical-intensive approaches, HPSA relies on selective mechanical liberation—eliminating leachability while preserving recoverable value.

Environmental remediation and strategic material recovery occur simultaneously.


EPA Treatability Study

In partnership with the U.S. Environmental Protection Agency, DISA conducted a treatability study on uranium-bearing waste material from the Navajo Nation.

Results demonstrated:

— Up to 98% reduction in contamination

— Elimination of leachability in treated materials

— Mechanical liberation of uranium-bearing fractions from waste streams

These results validated HPSA’s ability to materially reduce environmental risk while recovering uranium already mined and above ground.


Federal Licensing & Regulatory Validation

In September 2025, DISA secured a landmark NRC license, establishing a federally approved pathway to remediate legacy uranium waste and recover uranium for domestic use.

The NRC’s Environmental Assessment concluded with a Finding of No Significant Impact (FONSI), clearing the pathway for licensed recovery under federal oversight.

This milestone establishes a formal regulatory framework for projects that:

— Reduce contamination at legacy uranium sites

— Recover uranium suitable for reintroduction into the domestic fuel cycle

Navajo Nation Partnership

Remediation in Partnership. Verification at Scale.

DISA has worked in collaboration with the Navajo Nation and the Navajo Nation EPA to advance a measurable, field-deployable remediation pathway. From EPA-supervised treatability testing to a commercial-scale verification study slated for 2026, this work has been guided by transparency and local decision-making.

Phase II Commercial-Scale Verification (2026)

Building on Phase I results, DISA and the Navajo Nation are commencing a Phase II Commercial-Scale Verification Study at the Old Church Rock Mine site to:

— Demonstrate commercial-scale capability

— Validate continuous real-world operations

— Confirm environmental performance at scale

— Eliminate leachability and reduce waste volume

— Restore land for safe use


THE SCOPE OF THE CHALLENGE

Thousands of legacy uranium sites remain across the Western United States. HPSA is designed to deploy at scale—bringing a repeatable mechanical solution to waste sites across federal, tribal, and state lands.

Thousands of AUM sites, including 4,200 Defense Related Uranium Mine (DRUM) sites, remain littered across the American West.
TAILINGS

RECOVER VALUE. IMPROVE STABILITY. REDUCE WASTE.

Tailings often contain recoverable value due to incomplete liberation in legacy circuits. HPSA provides a modular, mechanical pathway to unlock that value—without overgrinding or major infrastructure changes.

HPSA for Tailings

— Selective mechanical liberation to unlock residual mineral value

— Improved grade and recovery without excessive fines generation

— Lower energy and wear than conventional regrind systems

— Direct integration into existing tailings streams

— Skid-mounted, modular deployment with minimal site modification

Evaluate reprocessing potential quickly, with limited capital exposure and measurable performance validation.

In partnership with Regeneration and ElementUSA, HPSA 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.

We do not guess. We measure.
