Amino-Dithiophosphate
Amino-Dithiophosphate is a highly efficient flotation collector for sulfide ores, particularly suited to the separation of complex polymetallic sulfide ores. It appears as a white solid powder with an active ingredient—Dianilinodithiophosphoric acid—content of no less than 95.0%. It features low impurity levels and water-insoluble matter content of ≤0.5%. The reagent demonstrates exceptional collecting performance and unique selectivity in acidic to weakly acidic environments.

Characteristics & Applications
- In acidic media (pH 3-6), Amino-Dithiophosphate exhibits strong selective collection for lead and zinc sulfide minerals, enabling efficient separation in lead-zinc-sulfur and copper-sulfur systems. The dithiophosphate and aniline groups in its molecular structure work synergistically to form stable hydrophobic films on mineral surfaces, greatly enhancing the flotation recovery of target minerals.
- The reagent has weak collecting action toward pyrite, effectively suppressing pyrite flotation under acidic conditions. This reduces its interference with lead-zinc concentrate quality and facilitates the production of higher-grade concentrates.
- It possesses good 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.
- 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.
Key Advantages
- Excellent selective collection for lead-zinc sulfide ores in acidic pulp environments, with strong adaptability.
- Effective suppression of impurity minerals such as pyrite, contributing to higher concentrate grades.
- Stable foam properties for easy operation and control, adaptable to various flotation equipment requirements.
- Chemically stable, facilitating convenient storage and use, which helps reduce production costs.
- Particularly suitable for the separation flotation of complex polymetallic sulfide ores, effectively increasing metal recovery rates.
