High-Efficiency Flotation Agent Amino-Dithiophosphate for Mining
Product Description
Amino-Dithiophosphate is a highly efficient flotation collector specifically formulated for sulfide ores, with exceptional performance in separating complex polymetallic sulfide ores. This white solid powder contains a minimum of 95.0% active ingredient—Dianilinodithiophosphoric acid—and features low impurity levels with water-insoluble matter content of ≤0.5%. The reagent delivers superior collecting performance and unique selectivity in acidic to weakly acidic environments, making it ideal for separation flotation of lead-zinc sulfide ores from pyrite, chalcopyrite, and other minerals.

Characteristics & Applications
- Selective Collection: In acidic media (pH 3-6), Amino-Dithiophosphate demonstrates strong selective collection for lead and zinc sulfide minerals, enabling efficient separation in lead-zinc-sulfur and copper-sulfur systems. The synergistic action of dithiophosphate and aniline groups in its molecular structure forms stable hydrophobic films on mineral surfaces, significantly enhancing flotation recovery of target minerals.
- Pyrite Suppression: The reagent exhibits weak collecting action toward pyrite, effectively suppressing pyrite flotation under acidic conditions. This reduces interference with lead-zinc concentrate quality and facilitates production of higher-grade concentrates.
- Foam Modulation: Possesses excellent foam-modulating properties, generating a stable and non-excessive foam layer that helps maintain hydrodynamic balance in the flotation process, prevents launder overflow, and improves separation efficiency.
- Temperature Stability: The reagent is insensitive to changes in pulp temperature, maintaining stable flotation performance across different seasons and regions, making it particularly suitable for continuous industrial production.
