Sodium Diethyldithiophosphate
Product Description
Sodium Diethyldithiophosphate is a highly efficient and selective flotation collector for sulfide ores. It appears as a yellow-brown liquid with its main active ingredient—sodium diethyldithiophosphate—content stable between 46% and 49%. The pH value ranges from 10.0 to 13.0. The reagent boasts excellent water solubility and chemical stability, allowing rapid mixing with pulp at room temperature and immediate collector action. As an important flotation reagent, it is widely used in the processing of non-ferrous metal sulfide ores, particularly demonstrating outstanding selective collection performance in the flotation separation of copper, lead, and zinc sulfides.

Characteristics & Applications
- Superior selective collection: Sodium Diethyldithiophosphate exhibits excellent selective collection for copper, lead, and zinc sulfide minerals. The dithiophosphate groups in its molecular structure form stable chemical bonds with metal ions on mineral surfaces, significantly enhancing mineral hydrophobicity and improving particle-bubble attachment efficiency.
- Inhibitory effect: The reagent shows obvious inhibitory effect on iron sulfide minerals such as pyrite and pyrrhotite. Under appropriate pH conditions, it selectively inhibits iron sulfide flotation, facilitating effective separation between target minerals and iron minerals.
- pH adaptability: The reagent adapts well to changes in pulp pH, maintaining stable collecting performance across a broad alkaline range. It is particularly suitable for treating complex polymetallic sulfide ores and demonstrates consistent flotation performance under various mining conditions.
Key Advantages
- High-efficiency collection of major non-ferrous metal sulfides such as copper, lead, and zinc, with excellent selectivity
- Marked inhibitory effect on iron sulfide minerals like pyrite, contributing to higher concentrate grade and quality
- Excellent water solubility and dispersibility, facilitating onsite use and dosage control
