High-Efficiency Dithiophosphate 25 for Lead Copper Silver Ores
Dithiophosphate 25 is a combined mineral processing agent that integrates both collecting and foaming functions. It appears as a dark brown, oily liquid, with its main active component—xylenol dithiophosphoric acid—comprising 60% to 70% of the content. The density at 20°C is 1.17-1.20 g/cm³. This reagent offers notable chemical stability and shows varying collecting performance under different pH conditions.

Characteristics & Applications
- Shows potent collecting capability for sulfide minerals of lead, copper, and silver, and is also efficient in processing activated zinc sulfide ores. Its molecules adhere to mineral surfaces via hydrophobic groups, significantly boosting surface hydrophobicity and encouraging the attachment of target minerals to bubbles.
- Collecting action is highly pH-dependent: under alkaline conditions, it has a weak effect on pyrite, supporting preferential flotation. In neutral or acidic environments, it serves as a strong, non-selective collector for most sulfide minerals.
- Natural foaming ability decreases the requirement for extra frothing agents. Helps create a foam layer with appropriate bubble size and stability, enhancing separation effectiveness.
Key Advantages
- Effective collection of lead, copper, silver, and activated zinc sulfide ores, with wide applicability across ore types
- Strong selectivity in alkaline settings, aiding pyrite suppression and target mineral separation in complex ores
- Suitable for specific oxide ore flotation conditions, broadening its application scope
