Crystallisation & mineral processing

Control where crystals nucleate. Keep heat-transfer surfaces clean. Cut cycle time and lift recovery on leach and brine circuits. Same vortex platform already commercial at industrial scale. We are now at lab scale for WA minerals.

The challenge

Where mineral processing loses money

Fouling, slow leach kinetics and expensive brine recovery drain throughput and margin, often on the same circuit.

Poor nucleation control

Without control over where and when crystals form, crystallisers run long cycle times with little command of crystal size. That means low productivity, high capex and high energy use.

Encrustation & fouling

Scale and crust build on heat-transfer and crystalliser surfaces, cutting efficiency by 30-50% and forcing repairs, shortened equipment life and downtime-heavy cleaning.

Slow kinetics & costly water recovery

Leaching is throttled by mass transfer at the mineral surface, and evaporation dominates the cost of zero-liquid-discharge. Both push energy and reagent use ever higher.

Process crystallisation

Why vortex cavitation for crystallisation

The same hydrodynamic mechanism behind VORTA’s commercial crystallisation offering: nucleation and growth intensified in the bulk, with collapse kept off the walls.

Before

Uncontrolled wall nucleation

Crystals form on the impeller, shaft and heat-transfer surfaces. Cleaning cycles, lost efficiency and shortened equipment life follow.

After

Bulk nucleation with cavitation

Nucleation shifts to the bulk and collapse stays off the walls, so surfaces stay clean and heat transfer holds up run after run.

Process crystallisation

Key advantages

Higher purity, shorter cycles, tighter crystal size, and a path from lab loops to plant throughput.

Higher crystal purity

Controlled bulk nucleation limits impurity inclusion, so the product leaving the crystalliser meets tighter purity targets.

Shorter cycle time

Accelerated nucleation and mass transfer compress residence time in batch and continuous crystallisers, lifting throughput without extra tank volume.

Uniform crystal size

Consistent shear gives a tighter crystal size distribution, which matters for filtration, downstream handling and product spec in chemicals and minerals.

Enhanced mass transfer

Intense turbulence strips boundary layers at the crystal surface, so solute reaches the growing face faster than in conventionally agitated systems.

Linear scalability

The same reactor geometry scales linearly from lab loops to plant throughput on the commercial platform, so lab gains can be pursued at production flow rates.

Lower specific energy

Hydrodynamic cavitation delivers intensification at a fraction of the energy input of mechanical agitators or orifice-based devices.

Crystallisation is already a commercial application on the founders’ platform. See VORTA crystallisation

Beyond the crystalliser

Cavitation across the mineral circuit

The same inline vortex reactor also addresses leaching, flotation, encrustation and the energy cost of brine and ZLD recovery.

No encrustation or fouling

Because nucleation is driven in the bulk and collapse stays off the walls, heat-transfer and crystalliser surfaces stay clean. Less downtime for descaling, longer equipment life and better asset utilisation.

Leach intensification

Shockwaves and micro-jets continuously refresh the mineral surface and overcome solid-liquid diffusion limits, giving faster kinetics, higher recovery, and often less reagent per tonne.

Nanobubble mass transfer

Our new nanobubble capability floods the slurry with ultra-fine, long-lived bubbles, multiplying gas-liquid interfacial area to accelerate leaching, flotation and gas-driven reactions that are otherwise transport-limited.

Brine & ZLD water recovery

By keeping evaporative-crystalliser surfaces clean and intensifying separation, Vivarta protects heat-transfer efficiency and lowers the energy cost of recovering water from high-salinity streams.
