Product Description

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.
