Amino-Dithiophosphate Collector for Acidic Flotation and Pyrite Suppression
Amino-dithiophosphate is a high-performance flotation collector specifically designed for sulfide ores, demonstrating exceptional efficacy in separating complex polymetallic sulfide deposits. This white powdered solid contains diphenyl dithiophosphate as its primary active component (≥95.0% concentration) with low impurity content (water-insoluble substances ≤0.5%).

Characteristics & Applications
- Demonstrates effective and selective collection for lead and zinc sulfide minerals in acidic conditions (pH 3-6), enabling efficient separation in lead-zinc-sulfur and copper-sulfur ore systems. The synergistic effect of dithiophosphate and aniline functional groups promotes stable hydrophobic layer formation on mineral surfaces.
- Minimal collection effect on pyrite, effectively suppressing its flotation in acidic pulp. This reduces adverse effects on lead-zinc concentrate quality and supports production of higher-grade concentrates.
- Excellent foam regulation properties create consistent, controllable foam layers that maintain hydrodynamic stability during flotation, minimizing overflow issues and improving separation performance.
- Maintains consistent performance despite slurry temperature variations, providing reliable flotation results under seasonal and regional climate changes - particularly suitable for continuous industrial operations.
Key Advantages
- Superior selective collection performance for lead-zinc sulfide minerals in acidic pulp systems with strong process adaptability
- Effective suppression of impurity minerals like pyrite, enabling higher product grades
- Consistent foaming behavior for smoother operation and control across various flotation equipment
- High chemical stability for easy storage and application, reducing overall production costs
- Particularly effective in differential flotation of complex polymetallic sulfide ores, improving overall metal recovery rates
