The REACT System — Real-Time Conditioning for Rare Earth Processing
The REACT System (Real-Time Elemental Assay & Conditioning Technology) is Ozzy Services’ proprietary innovation for stabilizing and optimizing rare earth process slurries.
It bridges the gap between leaching and precipitation, delivering clean, on-spec feed that improves yield, reduces chemical waste, and provides real-time data for operators and agencies alike.
In short: REACT gives U.S. plants the precision of China’s roasting-based systems—without the heat, emissions, or cost.
How REACT Works
REACT acts as a smart, modular skid that continuously filters, measures, and reconditions slurry before it moves to recovery.
It monitors key parameters—pH, turbidity, REE concentration, and thorium levels—and automatically routes off-spec material back for correction.
Core Workflow:
Leach liquor intake: Slurry enters a buffer tank with pH microdosing and agitation.
Hydrocyclone cluster: Removes coarse or problematic fines down to 5–15 µm.
Reconditioning tank: Short-residence buffer for chemical or flocculant adjustment.
Sidestream analytics: Inline XRF, UV-Vis, and gamma detection for thorium compliance.
Smart routing network: AI-driven logic decides “go” or “no-go,” looping material until it meets spec.
Think of it as custody-transfer-grade QA for mineral processing—a live feedback loop that makes every gallon count.
AI-Driven Precision
REACT’s dual sensor legs and AI controller validate every measurement in real time.
The system applies solubility product constants (Ksp) to predict precipitation risk and optimize reagent dosing on the fly.
If the sensor legs disagree, REACT self-cleans, isolates the fault, and continues operation without downtime.
Result: Consistent feed quality, 10–30 % lower reagent use, and stable precipitation performance—all verified by live data.
Two Applications, One Foundation
REACT for Rare Earth Elements
Designed for leach streams from deposits like Bear Lodge (WY) and Mountain Pass (CA).
Includes inline XRF and thorium detection for DOE/DoD-grade compliance.
Up to 95 % recovery without roasting
25 % waste reduction
Fully modular—1 to 100 tpd capacity
REACT for Coal & Industrial Slurries
Engineered for coal ash, tailings, red mud, and other fine industrial waste streams.
Uses a recycle and floculant system to analize and stabilize feeds as low as mg/L in REE content.
Converts waste to recoverable feedstock
Produces time-series data for pilot grant reporting
Reduces chemical use and turbidity discharge
Both systems share the same backbone: hydrocyclones, reconditioning loops, analytics, and intelligent routing—all on a transportable skid.

“We designed REACT to bring refinery-level discipline to REE processing — measurable, repeatable, and mobile.”
Why It Matters
Enables U.S.-based REE recovery at global yield levels
Cuts chemical and energy use by up to 30 %
Generates real-time process data for compliance and optimization
Portable, skid-mounted, and scalable
ROI in under two years for pilot deployments
The REACT System turns variability into predictability — and waste into value.
