DY366 Scandium extractant

DY366 Scandium Extractant
The DY366 Scandium extractant is an advanced organophosphorus chelating reagent, specifically for the high-selectivity of Scandium from complex acidic multi-metal systems. DY366 forms exceptionally stable, targeted complexes with scandium ions, to unlock high-purity value from complex secondary waste streams and ore residuals.
Unlike traditional, non-specific extractants that suffer from heavy co-extraction of coexisting iron, aluminum, or titanium, DY366 features an optimized molecular structure that prioritizes scandium binding. This dramatically shortens processing circuits, lowers mineral acid consumption during stripping, and increases the overall recovery margins of Scandium Oxide.

Targeted Industrial Applications of DY366 Scandium extractant:
Optimize the recycling and recovery of scandium-containing resources in the following sectors:
1. Laterite Nickel Ore Smelting
In High-Pressure Acid Leach operations for laterite nickel-cobalt ores, scandium concentrates heavily within the iron-aluminum slag and downstream waste liquors.
DY366 selectively isolates scandium from high concentrations of nickel, cobalt, and iron.
2. Red Mud (Bauxite Residue) Valorization
Bauxite processing for aluminum production leaves alkaline red mud rich in rare elements.
Following specialized acid leaching steps, DY366 can capture liberated scandium from complex aluminum-iron matrices.
3. Titanium Dioxide Waste Acids & Tungsten Slags
DY366 can process titanium sulfate waste liquors and tungsten refinery sludge, in strongly acidic industrial liquid effluents.

Performance Advantages of DY366 Scandium extractant:
Exceptional Selectivity Matrix: Accurately targets and isolates in complex multi-metal liquors, minimizing chemical cross-contamination and reducing the number of scrubbing stages required.
Rapid Phase Disengagement: Excellent hydrodynamic properties limit organic phase trapping, resulting in extraction phase separation times of and reverse extraction times of . This translates directly to high volume throughput in continuous mixer-settlers.
Excellent Hydrolytic and Thermal Stability: Highly resistant to chemical degradation under aggressive acidic conditions, allowing the organic phase to be continuously recycled and regenerated without losing loading kinetics.
Eco-Friendly Engineering: By maximizing single-pass extraction yields and easing back-extraction loops with optimized stripping agents, DY366 cuts wastewater load and processing energy requirements.

Packaging, Storage, and Logistics: Supplied globally in 25kg plastic drums, 200kg steel-plastic composite barrels, or heavy-duty 900kg/1000kg IBC containers.
Product must be stored in a cool, dry, well-ventilated warehouse separate from strong oxidizers and open heat sources.
