CASE STUDY: Jet-Pump Fluidizer Technology

Across mining operations, one challenge is both universal and notoriously costly: the ongoing build-up of compacted slimes and solids in process-water dams.

Over time, these dams accumulate dense layers of sediment on the floor, material that becomes so compacted that conventional pumps can’t move it. As the sludge layer grows, water-holding capacity decreases, dam efficiency drops, and operations are forced into expensive interventions like manual excavation, mechanical dredging, or complete shutdowns to restore flow.

Add to that the safety risks, downtime, and logistics of cleaning dams the old way, and it’s clear why operations are urgently seeking better, continuous, and more cost-effective reclaim systems.

This is exactly the problem the Aranzu Fluidizer was engineered to solve.

THE PROBLEM:
Compacted Slimes That Pumps Can’t Move.

Mine water circuits rely on steady reclaim and predictable flow. But sedimentation ponds, storage dams, and process-water basins all suffer from the same issue:

  • Solids settle and compact forming dense, immobile layers
    These materials often resist suction, even with high-capacity pumps.
  • Pumps choke, cavitate, or run dry
    When solids aren’t mobilised, reclaim efficiency collapses.
  • Buildup reduces dam capacity and system performance
    Meaning more frequent dam interventions and higher associated costs.
  • Traditional dredging is expensive, disruptive, and risky

Mechanical equipment, divers, or manual clearing poses additional safety challenges.

Operations need a way to continuously mobilise solids, not only when the dam becomes a problem.

THE ARANZU SOLUTION:
Jet-Pump Fluidizer Technology

The Aranzu Fluidizer is a venturi-based jet pump that uses pressurised motive water to break up compacted solids at the dam floor and pull them into slurry suction lines.
It turns settled mud back into pumpable slurry — automatically and continuously.

By injecting high-velocity water through a precision-engineered nozzle, the unit creates intense local turbulence. This:

  • breaks up compacted layers,
  • lifts solids from the dam floor, and
  • keeps them suspended long enough for pumps to transfer them out of the system.

The system can be installed as:

  • a single point for focused agitation, or
  • a multi-point array for broad coverage in large dams — all linked to an isolation manifold for easy control.

Whether fixed in place or moved as needed, the Aranzu Fluidizer integrates seamlessly with existing pump systems.

WHY IT WORKS SO WELL:

  1. Jet-Induced Suction = Reliable Solids Mobilisation
    The venturi effect creates a powerful suction zone that continuously pulls mobilised solids towards the pump inlet.
  2. Turbulence Breaks Down Even Hard-Compacted Slimes
    The spray-bar or nozzle assembly generates enough agitation to disrupt settled layers — solving the core problem pumps alone cannot.
  3. Modular, Scalable Design
    Units can be deployed wherever solids accumulate, including irregular dam layouts or underground basins.
  4. Built to Withstand Harsh Mining Conditions
    All hoses, fittings, and wetted surfaces are made from abrasion- and corrosion-resistant materials chosen for each site’s chemistry and slurry profile.
  5. Works With Existing Infrastructure
    The system integrates easily with current reclaim pipelines, pump configurations, and water circuits.

THE BENEFITS:
Cleaner Dams, Fewer Shutdowns, Lower Costs

Aranzu’s fluidization technology delivers measurable operational advantages:

  • Continuous or on-demand de-sludging
    No more waiting until the dam becomes a crisis.
  • Reduced downtime and lower maintenance costs
    Keeping solids mobilised protects pumps, valves, and screens from overloading or blockage.
  • Improved dam capacity and reclaim efficiency
    More of your water becomes usable again without costly dredging campaigns.
  • Safer, simpler operations
    No need for divers, heavy mechanical dredgers, or invasive excavation.
  • Tailored to your site’s slurry conditions
    Every Aranzu Fluidizer system is engineered for the dam geometry, water chemistry, density, and duty cycle.
  • Future-ready integration
    Compatible with manual or automated controls, manifolds, and smart monitoring if required.

CONCLUSION:
A Modern Way to Manage an Old Mining Problem

Compacted slimes will always settle in process-water dams, but with the Aranzu Fluidizer, they no longer have to disrupt operations, reduce capacity, or force costly interventions.

By turning settled solids back into pumpable slurry through controlled jet-induced mixing, Aranzu delivers a high-efficiency, low-maintenance, and scalable solution that keeps dams clean and reclaim lines running smoothly.
