Primary Applications & Zielmetalle
Through precisely controlling the pH gradient and organic concentration, DY377 is suitable for directional multi metal extraction processes:
1. High-Efficiency Nickel and Cobalt Separation
In laterite nickel processing circuits and lithium-ion battery black mass recycling loops, DY377 acts as an excellent separator. It selectively segregates cobalt and nickel ions from highly concentrated sulfate or chloride systems, presenting an excellent alternative or complement to traditional phosphinic acid reagents.
2. Transition Metal Recovery & Wastewater Purification
DY377 displays robust extraction affinity for an array of transition elements, making it ideal for processing smelting byproducts and treating industrial effluents:
Cadmium, Manganese, and Molybdenum extraction. Titanium, Lead, Kupfer, and Antimony separation.
3. Precious Metals Enrichment
The diglycidyl bisamide structure offers exceptional coordination stability with noble metal complexes. Refineries deploy DY377 to selectively trap and enrich trace concentrations of Gold, Platin, and Silver from complex anode slimes and electronic waste scrap leaching streams.
Key Performance Advantages of DY377
Low Operating Density & Viskosität: With a specific gravity of and a low dynamic viscosity, DY377 mixes cleanly with standard diluents, minimizing emulsion issues and optimizing mass transfer rates.
Rapid Phase Disengagement: Achieves clear boundary separation within short cycle times. This prevents organic carryover loss and maximizes output volumes in continuous counter-current mixer-settler loops.
Flexible Reverse-Extraction (Abisolieren): Loaded metal matrices can be easily back-extracted or reduced through optimized mineral acid profiles or reducing agent applications, returning a highly concentrated, pure aqueous stream ready for electrowinning or precipitation.
Enhanced Operational Safety: A high closed-cup flash point ensures a highly stable, fire-safe workspace in commercial solvent extraction plants.
